Hello group. My name is gravity, and I am addicted to coffee. Feel free to post "How can I make my lovely coffee moderately palatable?" type posts, but also be prepared to read replies from people who spend way too much time and money achieving the perfect shot.



Coffee comes from the seed of a fruiting bush grown in abundance all over the world on practically every continent, save Antarctica. Though there are over 90 species of coffee, there are only four species of coffee that I have ever tried, and only two of which see large scale production:

Species

Arabica – The earliest cultivated, most widespread, and “best tasting” coffee (in many people’s, including my own, opinion). This variety actually has the least caffeine of the two varieties. Arabica tends to have smaller beans and will be slightly more expensive per pound, which is why you may see some blends brag about being 100% Arabica. This is because many cheap blends contain:

Robusta – The filler coffee. Admittedly, it’s not really that bad, but it gets a bad rap because it is easier to grow, fruits prolifically, and produces bigger beans, all without being particularly remarkable in flavor or aroma. What robusta does bring to the table is a higher caffeine content and a more viscous mouthfeel, the latter of which can translate into better “crema” production in espresso, so you will often see robusta show up in espresso blends.


Origin

Coffee can also be categorized into three groups by style, then further into subcontinental regions and eventually by country.

* Latin American, Carribean, and Hawaiian Coffees tend to be “normal.” That is to say, the flavor and aroma of these coffees are what many people think of when they think of coffee. They are usually pretty balanced in profile but can still be quite robust and have a refined sweetness. The most sought after of all coffees come from this category such as Jamaican Blue Mountain and Hawaiian Kona.

* African Coffees are bright, lively, and rich. Some people call them wine-like, a description most often given to Kenyan coffees. They can also have a spiced or herbal nose as is the case for Ethiopian Yirgacheffes.

* Asian-Pacific Coffees are thick bodied, earthy, and have a rustic sweetness. They are really popular in the modern craft coffee scene as their earthiness takes to dark roasts particularly well. Varieties such as the Sumatran and New Guinean coffees are notable for this.



"Process"

The separation of the coffee fruit or "cherry's" flesh from the seed largely falls into one of two categories or some hybrid of the two:

Dry Process coffees' cherries are harvested, sorted, cleaned, and set in the sun to dry, being turned often and taking up to a month to dry. The seed is then removed with a hulling machine. Dry process coffees tend to be more "rustic" tasting, fruitier, and can be a bit inconsistent to roast.

Wet Process cherries are harvested, and sorted by using water, bad cherries float. They are then hulled by forcing through a screen, and fermented in its own moisture to allow enzymes to break down the mucilage, a gooey outer layer on the seed. The mucilage is then washed off and the coffee is dried in the sun. Wet process coffees are more consistent to roast and are cleaner and more "refined" tasting.

Semidry processing is a mix between the two. It utilizes hulling machines directly after harvest then allows for fermentation of mucilage, followed by minimal water washing, and drying. Semidry processing is relatively new and is only done in a few places, coffees tend to have the consistency and clean taste of wet process coffees, with the liveliness of dry.



__________________________Roast Levels__________________________



Aside from origin, the roast level of the coffee has a huge impact on the coffee’s in-cup flavor.

City, American, New England
Light-medium to medium brown in color, this roast is, generally, the best roast to taste the difference between regions as these differences will be obscured further and eventually completely the longer the coffee is roasted. Coffee roasted to a city roast tends to be grain-like sweet, and bright/acidy.

Full City, Continental, Viennese
Medium to medium-dark brown in color, this is my favorite roast as it still represents the varietal flavor with a nice backbone of roast flavor. Full city roasted coffee is still lively, but some of the acidy edge is rounded off giving way to a light sweetness.

French
Dark to deep dark brown in color, at this roast level only the most robust varietal flavors are left, all of the nuanced tones, the liveliness, and the regional distinction has been roasted away. If I have a batch of green coffee I don’t care for the taste of, I will usually roast it to a French roast. French roasted coffee is mildly pungent, sweet, full bodied, and with nearly imperceptible acidity.

Starbucks
Deep dark brown to black in color, this roast level is about one notch away from charcoal. There is no varietal distinction; all coffees roasted to this level taste more or less the same. Starbucks roasted coffee tastes like burnt rubber.



__________________________Brewing Methods__________________________

Drip machine.

The most widespread method for brewing coffee, I’m sure. This method often relies on poorly designed heaters that begin to drip slightly warm water over coffee grounds. The heaters ramp up and eventually reach a temperature that is too hot. The coffee drips into a glass carafe that is placed on a heating element that is also set to be too hot causing the coffee to have a burnt taste. Some machines have stainless steel vacuum carafes that forego the carafe heater. If you must have a drip machine, get one of these. Resist the urge to use a gold tone metal filter. You defeat one of the biggest strengths of this brew method, the clean, sludge-free cup. Good paper filters have little to no “paper taste,” and if you combine with pre wetting, the “paper taste” should be non existent (with good quality filters). If you can swing it, get a Technivorm.



This is the Rolls Royce of drip coffee makers. They are hand made in the Netherlands, they have spray heads that evenly wet the coffee grounds and that don’t start spraying until the water has reached the correct temperature. They are completely dismantle-able for cleaning and maintenance. Get one.

Drip machine pros: Convenient, clean cup
Cons: Cheap models have no temperature control, there is no steep time control, heating elements can make coffee taste burnt, good models are big and take up a lot of space.

Edit: For those considering getting an automatic drip, consider the Bonavita http://www.clivecoffee.com/product/...l_coffee_maker.

K-Cup, Keurig, Single serve pods, etc.



A relatively new thing to come on to the market. They advertise quality, convenience, and environmentalism and deliver on none of them. Read this:
http://www.dearcoffeeiloveyou.com/love-keurig-nope/

Pros: You'll get a lot of comments at the office about how trendy you are, I guess that's a pro.
Cons: All the cons of a cheap drip machine. Poor quality coffee pods that you over pay for. Lots of plastic waste.


Pour over



A drip coffee method where you are the “machine” part. This allows you to have precise temperature control with an electric kettle and an instant read thermometer.

Examples: Hario V60 02 Clear ($8, needs proprietary filters), Chemex ($30, needs proprietary filters)
Pour over pros: CHEAP, small, cheap, ability to have very accurate temperature control, clean cup, did I mention cheap, yeah it’s cheap.
Cons: Requires you to actively brew the coffee, no full immersion or steep time control, requires a hot water source such as an electric kettle.

Pour overs COMPARED:
Melitta: the classic.

The cheapest, easiest to find, and easiest to find filters for. One small hole at the bottom restricts flow of the coffee just enough to make extraction almost fool proof. Uses standard cone-type filters. There are variations on this type of brewer such as the beehive which has 3 holes. Not really all that different, just drains faster, which can either be a pro or a con depending on your technique.

Hario V60: the sperglord's choice.

Super thin proprietary filters, deep cut spiral ridges, one gigantic friggin hole at the bottom. This is probably the most finnicky of all the filtercones since it drains so fast. Because of this, improperly brewed cups will tend to be under developed, but on the plus side, you have to try really really hard to overextract in one of these. Many argue that you NEED to have a gooseneck kettle to get any kind of consistency from these.

Chemex: the geezer.

This brew method has been around for a long time now. An hourglass shaped carafe with wood around the waist to keep you from burning yourself holds a nestled quadrifold circle or square filter. Super thick proprietary filters give you the cleanest, smoothest cup of all of the pourovers. This comes at the expense of more paper taste in the cup (though this can be avoided by rinsing the filter multiple times).

Kalita Wave: the new kid.

Proprietary filters with a flat bottom and 3 drain holes. This is the newest darling on the scene and it has its fans who claim that it provides a cup like the V60 with less finnickiness. It also has a specialty kettle, though I would probably just get a gooseneck.

Press pot, French press



A full immersion coffee brewing method where coffee is brewed, then the grounds are separated by using a mesh screened “plunger.” The result is a very flavorful and nuanced cup of coffee that still has many of the volatile oils since it has not passed through a paper filter.

Examples: Bodum Brazil 8 cup (no nonsense, black plastic) ($20), Bodum Chambord 4 cup (prettier w/ metal and stuffs) ($35)
Press pot pros: Accurate immersion time and temperature control, no paper filters, modestly priced.
Cons: Requires hot water source, cups brewed with a press pot are almost always murky or sludgy, can cause cholesterol spikes for people with cholesterol problems, carafes are quite fragile.

Clever Coffee Dripper



My personal favorite morning cup maker. This method is basically a pour over with a stopper on the bottom. It effectively blends the strengths of both pour over and press pot, with none of the weaknesses, except the convenience, I guess… The stopper on the bottom is very convenient, though. It activates anytime it is not on a cup, and when you place it on the top of one it releases the coffee. Pretty nifty.

buy them here ($15):
http://www.sweetmarias.com/sweetmar...h-lid-2973.html

CCD Pros: Immersion time and temperature control, clean cup, affordable.
Cons: requires hot water source

Aeropress



Kind of like an overgrown syringe that you place over your cup of coffee. Because you are actively forcing the water through the coffee grounds with pressure, coffee brewed in an Aeropress will have slightly different flavor than these previous ones (I guess they all will, technically, but Aeropress is the first one I’ve mentioned to have applied pressure be one of the variables).

These are about $25
Aeropress Pros: Rich coffee, clean cup, Immersion time and temperature control, affordable
Cons: Requires special filters that you usually can’t just go to the store to pick up, requires hot water source.

Moka Pot



Often called a “stove top espresso maker,” moka pots brew small quantities of robust, rich, coffee. It is technically not espresso as the pressures at which a moka pot operates are quite low compared to “real” espresso makers. Nevertheless, moka pots brew great coffee and are perfectly fine for use in milk-based coffee drinks, or “Americanos”.

Small ones run about $25.
Moka Pot Pros: Small, affordable when compared to proper espresso machines
Cons: Requires a stove, many don’t work on induction ranges, doesn’t make “real” espresso.

Espresso Makers

This is a big can of worms that I don't know that much about. Thanks to Bob_McBob for helping me write this section. Espresso makers tend to fall into 1 of 3 categories, then further into subcategories:

Semi Automatic Machines

These are the majority of the market. They have a steam wand and can cost anywhere from 50bux for a cheap POS up to thousands of dollars for a crazy multi head machine with a PID for the water temperature, and on and on and on...

Thermoblock steam toys



“fake” espresso makers are basically like cheap drip machines, they use heat to generate pressure which is often too low and inconsistent, they have poor temperature control, because pressure is generated with temperature the brew temp is too hot, they are made with cheap plastic parts, and have thin walled pressurized portafilters. If you are after espresso and are only willing to spend as much as these are, save your money.

There may be an exception to this rule should ZPM Espresso ever release their project espresso machine which uses a custom thermoblock in conjunction with a PID for both pressure and temperature and with user customizeable shot profiling. They are about a year overdue for release though and though the promises are big, who knows if they'll deliver. Even if they do deliver, with a street price of $350, you're well into the price range of single boiler machines.

Single boiler dual use machines



These have one boiler and a seperate pump that applies 15 bars of pressure to your puck of tamped ground coffee. Because they have one boiler, they require you to heat up the water for brewing then heat it again to use the steam wand.

At the low end you have the Saeco Aroma ($230, but as low as $130 refurbished) and Via Venezia ($300). The nice thing about these is that SCG sells naked and unpressurized portafilters, should you desire to upgrade. The bad thing is they have lovely steam wands called pannarellos.

You can also go as low as a DeLonghi EC155 and take a dremel to the plastic bottom of the portafilter to make it bottomless. People get good results with this, but because it is a lower end machine, the walls on the portafilter are thinner making temperatures fluctuate more and it also has a weird size which can make finding a tamper hard. There is a lot of plastic on this machine, too.

At the top of this range is the beastly Rancilio Silvia ($630) which boasts a robust portafilter, sturdy construction, and a good steam wand. Some people say that this is the cheapest machine you should buy. For just a bit more is the Crossland CC1 which sports a nifty PID that helps alleviate one of the main problems with single boiler machines: temperature control.

Heat exchanger machines


These have one boiler that runs at the higher steam temperature dedicated to making steam. It utilizes a heat exchanger to interface water en route to the brew heads and heat it up to temperature.

Examples in this range are the Nuova Simonelli Oscar ($1000) and the Rocket Cellini ($1500)

Dual boiler machines


These have two boilers so you can brew and use the steam wand at the same time both held at independent and stable temperatures,

They often also have a lot more features like PID, hot water dispensing, industrial brewheads and steam pumps, etc.

Examples in this range are the Rocket R58 ($2700), the Izzo Alex Duetto ($2250) and the Rolls Royce of home machines: La Marzocco GS/3 ($6500)


Portafilters

Pressurized portafilters are fitted with a device that makes up for lackluster grinding and tamping abilities and provides a sort of fake “crema”. Because of this, these are often called “crema enhancers”. Some argue that this is also not “real” espresso, but it’s closer than the moka pot and the thermoblock stuff.

Nonpressurized portafilters lack the device that equalizes pressure in the portafilter, the result is a much more unforgiving pull, but when dialed in, produces “real” espresso. You NEED a good grinder if you want to make the most of this type of portafilter. A special type of nonpressurized portafilter is a naked/bottomless portafilter which just has a bare basket on the bottom. People like these because you can see the extraction happening and use the visual information to troubleshoot the brew variables.


Manual Machines



Manual espresso makers require you to be the pump. The beauty of a manual espresso maker is that, in the hands of a fantastic barista, they will pull the best shots you will ever have. Because they are manual they allow for finesse unlike the semi autos. They are expensive and most people will never use them, hell most people will never have a shot pulled from one by an experienced barista, and that is sad.

Super Automatic Machines



Automatic espresso makers do everything for you. They are very expensive and make pretty mediocre espresso shots.




__________________________Extraction: the Big Picture__________________________



So I've hinted a few times about "properly extracted" coffee. There are 4 main components that determine how extracted your coffee is: Grind, Time, Ratio, Temperature. Photographers can probably understand this quite easily if I were to say that extraction is like exposure. Where in photography you can achieve "correct exposure" by dialing in various ISO, shutter speeds, and apertures, one can achieve proper extraction by dialing in the 4 extraction variables.




Grinders



Quite possibly the most important thing when you are considering a coffee rig. Why? Well coffee is all about extraction but not everything in the bean is desirable on the palate. Many of us are familiar with the over extracted cardboard-like bitter taste of lovely office/diner coffee. Apart from just being lovely preground coffee, often a big contribution to the awfulness is that people use too little coffee to the amount of water they use which results in an overextracted cup. What does this have to do with grinders? Well different particle sizes of ground coffee extract at different rates. Smaller particles will become overextracted before large ones, therefore grind consistency is very important in coffee making. If you are looking at getting an espresso rig, you MUST NOT skimp on your grinder. Avoid blade grinders like the devil, they chop the beans instead of grinding them giving you a VERY inconsistent grind, the high speeds with which the blades rotate cause lots of friction problems which translates into lost volatile oils. Good grinders use nestled burrs that are spaced apart and that rotate at a slow rate. The result is an even, consistent grind. If you are looking for a grinder for pour over or press pot methods, a Baratza Maestro (refurb for $70, check the Baratza site often), Virtuoso (refurb for $143) or Capresso Infinity ($90) is usually a good choice. If you want an espresso capable grinder, buy the absolute best you can afford. Many people like the Baratza Vario ($400) and the Rancilio Rocky ($350).



On the other end of the spectrum are manual grinders. I have one myself for my travel rig (yes I have a travel rig, I am aware I have a serious problem). Manual grinders are great because they are cheap and consistent. They are best mated to drip or press pot methods as coarser grinds are quicker to grind. Grinding for espresso or Turkish coffee with a manual grinder would seriously suck. I have a Hario Mini Mill Slim ($30), the Hario Skerton is also good. Funny story about the skerton, it is actually a typo (I am not making this up, or at least I heard it from the seattlecoffeegear ladies so blame them). Hario is a Japanese company, supposedly the original name is the "Skeleton," but apparently there were some problems in pronunciation... (skerreton)



Ratios and the Importance of Scales

There have been a lot of questions about ratios and most have a mention of how many "scoops" per "cup". This is a really inaccurate way of measuring coffee. Scoops are bad because there are different scoops, some coffee is denser than others, some beans are bigger than others and will fit in a scoop differently, some people are talking about ground coffee which is different still. Cups, you would think, is universal, but in coffee world some people use the 6 oz cup standard. No, the best way to dial in a ratio is to use mass (ok we're really measuring weight but I like grams and grams are a unit of mass). I prefer grams because 1 mL of water is 1 g and the ratios also come out prettier and easier to remember (as is usually the case for metric vs imperial).

There is a great chart of ratios here: http://www.sweetmarias.com/grind.brew.php

But really you only need to remember one number: ~18. The SCAA's guideline is for 177 mL of water, use 10 g of coffee. So if we were to take the ratio we'd get 17.7 or roughly 1:18 coffee:water. How do we use this? Well, place your favorite cup on your scale. Tare it. Fill up your cup to the desired level with water. Take a note of how much water that is and divide by 18. The resulting number is a good starting point for drip coffee methods such as various filter cones and Technivorm/Bonavita. If it's too weak you can tune from there, but this is also dependent on your extraction time and grind fineness so it will take some experimentation. For instance, I know that I take my V60 grind quite small by comparison to others. For French Press, I like about 1:17 for the grind size I use.

So yeah, get a scale, preferably with at least 0.1 g resolution. They're not expensive, and you should be using them elsewhere in the kitchen, anyway. You can use it later in the brewing process (for pourover/french press) by placing the whole brew rig (cup, cone, rinsed filter) onto the scale and zeroing. Then you can add your ground coffee and crosscheck that you have the same mass you started with before the grind (you won't). You can redo your maths (if you care enough ). Then you can use the scale to monitor how much water you're adding to make sure you get to exactly the correct ratio.



Temperature
Ideal brewing temp for coffee is 195-205 F. There's a tiny bit of variation here, but as long as you're within the range you should be fine. You can get ~205F by bringing a kettle of water to a boil then letting it sit for a few minutes.

Time

Pourover aim for about 2 and a half minutes
Press pot ~5 min
drip/CCD ~ 6 min
Aeropress/espresso ~ 30 sec



__________________________Sourcing Coffee__________________________



Coffee beans are very sensitive to how recently they were roasted. They “outgas,” letting off CO2 right after they are roasted, this CO2 makes a sort of “protective barrier” keeping the coffee from going stale. Because coffee outgases, it needs to be packed in special bags with one way valves. Once the coffee is completely outgassed, there is nothing protecting its oils from going stale or evaporating off. Optimally you should consume coffee within 2 weeks of its roasting. Coffee that comes vacuum sealed has been allowed to completely outgas, and was therefore already stale before it was vacuum sealed. If not, the act of sealing the coffee before it was done outgassing would give you a poofball of air and coffee. Store fresh roasted coffee in a sealed container, if it is truly fresh (as in roasted that day) keep the lid ajar to allow the excess CO2 to escape.

Because you shouldn’t buy more coffee than you can consume in a 2 week period, it is important to find a local roaster. Local roasters ideally roast twice a week, though once a week is fine, too. Nice thing about local roasters is that you are supporting local business, which is also a good thing. There are also a few really good places to get fresh roasted coffee online, but it can get pricey, especially if you order from places like intelligentsia.

If you feel the need to freeze your coffee you are arguably buying too much at one time. If you absolutely must freeze, try and use vacuum bag devices like foodsavers, and consume all the coffee before 2 months after the roast date, this is admittedly less than ideal.













__________________________Roasting Coffee__________________________

By far, the most affordable way to get high quality roasted coffee is to roast it yourself. This may seem absurd to many of you, but the notion that you can go to the store to buy ready-to-brew coffee is only about 100 years old. Fresh, home roasted coffee fell by the hands of industrialization. Roasting coffee used to be a thing that everyone did once a week. These days coffee is a bland cardboard tasting brown granule that comes from a can. This is unfortunate, as home roasting is really no more of a chore than doing the dishes.

The easiest way to get into home roasting is with either a stovetop whirley pop popcorn popper or a hot air electric popcorn popper. Both of which can be found at a thrift store for chump change. I, personally, use a stove top whirley pop. If you use an electric popper, use it outside, the flying chaff can be quite messy. Nice thing about the whirley pop is that it has a lid so the chaff stays contained. You also need two colanders. A fan and a spray bottle is also useful.

Here is a useful guide!

http://www.sweetmarias.com/roasting-VisualGuideV2.php

Here is a guide on how to use a Stir Crazy to roast coffee (thanks scythide): http://biobug.org/coffee/turbo-crazy/

Method for stovetop poppers

Heat the inside of your popper to 450F. Add coffee and start stirring. When your coffee has reached the desired roast level, take your popper outside and dump the coffee into one of the colanders. Pass the coffee back and forth between the colanders to allow the chaff to escape and to quickly cool the coffee. Doing this with a fan helps clear the chaff and cool the coffee. You can also spritz the hot beans with a couple of sprays of clean water. This is called water quenching. If you do this, note that you are not actually wetting the coffee, you are evaporating water off of the surface of the coffee; the act of evaporation absorbs heat from the beans due to the latent heat of evaporation. You really should only spritz 2 or 3 times. The coffee should not be wet.

How to determine roast levels

Using color to determine the roast of your coffee is quite inconsistent. The best way to determine doneness is to listen to it. Over the course of roasting, your coffee will undergo two periods of snapping and popping called the first and second “cracks.”

As the first crack ramps up it will eventually reach a peak then trail off. If you allow the first crack to happen and stop immediately after it is finished you have roasted a “City roast.” As mentioned, City roast coffees are bright and lively, and retain the strongest origin character of the roast levels. Allowing the coffee to darken slightly past the city roast level is often referred to as City+ or C+. Stopping just shy of the first crack’s end is often referred to as New England roast.


This is an Ethiopian Yirgacheffe roasted to about a C+

Allowing the roast to continue you will eventually reach the start of the second crack. Stopping when you hear the first few pops of the second crack will give you a “Full City” roast. As mentioned, Full City roasts offer good origin character with a bit of roast character. Allowing the second crack to actually develop for a bit longer gives you a Full City+ roast or FC+.


this is a Nicaragua Nueva Segovia, roasted to a FC

Allowing the roast to continue to the point of a rapid second crack gives you a French roast. As mentioned, a French roast is almost completely roast character, only a few coffees can retain origin at French roast stage, Sumatran, for instance. Between FC+ and French is sometimes called Vienna roast. Just past French is sometimes called Italian or Spanish roast.


this is an Indonesia Sulawesi Toraja Sapan roasted to about a Vienna.

Allowing the second crack to finish is a fire hazard, don’t do this.

Stay tuned, more to come!

Thanks for the help guys! I think I'll start out with a cheap grinder (any suggestions for the cheapest I can get, to start, that'll be worth using? I'm ok with hand operated if need be. Also a french press to make it in because that way I get to keep more of the oils compared to the paper filters used with the clever coffee dripper. As for beans I'm going to probably order some online to start since none of the local popular shops seem to do their own roasting around here.

Forever ago, I picked up a like $15-25 Black & Decker burr grinder. Is this Utter poo poo, Better than a blade-grinder, all/none of the above, etc? At the rate I drink coffee, something better would probably be a sound investment, but I'm not so sure for our friend who doesn't drink coffee that often.

The biggest problem with blade grinders is that because the blades spin so fast, they don't actually grind the coffee, they chop it haphazardly. These spinning blades become a headache for good, consistent coffee making. I highlight consistent because, yes, you can make a good cup with a blade grinder, however press pot coffee will be very sludgy, proper espresso is impossible, moka pot will probably clog more often than not, and achieving proper extraction is a crap shoot. In addition, the blades move so fast that they start to heat the coffee which can destroy volatile oils. Now it's also important to know that coffee isn't purely "extract everything you can out of this bean." If that were the case, blade grinders wouldn't be so bad, however "overextraction" is definitely a thing. There are flavor compounds in a coffee bean that give you that cardboard-like, stale popcorn flavors, to bitterness and so on. It just so happens that these compound are only extracted en masse when certain extrema are hit. A few of these have been mentioned, extremes of temperature and extraction time, however it is important to note that extraction time is dependent on grind size. This is why a lot of coffee people fap on and on about grind consistency. With a blade grinder, you run the whole gamut of grind sizes from medium large chunks to fine powders, and this makes establishing a brew time for consistent extraction impossible.

Anyway, that's the long, the short is, I'm willing to argue that any burr grinder is better than any blade grinder, if only because you bypass the speed of grind issue and the chopping particulate inconsistency issue. Now what you get with a cheap grinder is cheap parts. Sometimes these grinders' burrs will rub when grinding fine, which shortens their life, there will often be a lot of plastic parts, and I mean important plastic parts, not just cases. Sometimes they will sacrifice other things like grind size steps, etc. So yes, your grinder is better than a blade, but not better than, say that Maestro.

I've already taken it apart quite a bit, as instructed. I really don't want to remove the case and get into troubleshooting motors and electrical bits for a few reasons. I've no experience in that sort of thing and am afraid I'll irrevocably damage the machine. It's not really because I'm "too lazy" to do it. I've done absolutely all of the troubleshooting they've asked of me up to this point, but I'm not a goddamn engineer.

As mentioned, you should really just have told them that it is under warranty and that you aren't comfortable taking it apart. Baratza actually has one of the best customer service reputations in the industry. I think you're overreacting.

The problem with Keurigs

They are sold under the premise that you can brew single cups of quality coffee with little mess (pods) anytime.

They have no temperature control or steep time control, they are basically miniaturized drip coffee machines. The coffee has been roasted who knows when and ground around that same time. These go completely against the notion of a quality cup. Therefore the Keurig does not brew a quality cup. A common retort is that they make a filter basket insert for Keurigs, but this just negates the convenience factor of a disposable pod, all the while you overpaid for a lovely drip coffee system. A single cup french press or a cheap rear end pour over costs 1/4 to 1/10 the price of a Keurig and makes significantly better coffee. Or you can just get a MrKrupsinart cheapo drip system for 1/3 to 1/2 the price of a Keurig and put significantly higher quality coffee in it, without the mark up of pod-ization, and brew a better cup.

Can anyone chime in on how effective the Aeropress is? I read the OP but I'm still not sure if it's worth it. My brother's a big coffee fan and currently uses a french press. I'm wondering if there will be a significant increase in quality of his coffee (he already buys fresh roasted beans and has an expensive grinder).

Saying an Aeropress is "better" is a bit misleading. It is very different from press pot and pour over.

As a Capresso Infinity user myself, I recommend the Baratza Maestro refurb. It is cheaper, has a better container (anti-static), more grind size quantizations, and has better burrs. Only reason I got the Capresso was because I had store credit at BB&B and they don't carry Baratza.

Do you not have a deck / patio thing at all? With a Whirley Pop, a heavy gauge extension cord, and a $10 hot plate from Walgreens, you're set to roast outside.

Roasting on a patio with a $10 hot plate in New York in winter would be pretty tough to do. I don't think those things put out enough heat for that sort of thing.

Yeah, moka pot, a frothing means of some sort(you can use a press pot).

I would definitely suggest a grinder if you can afford it.

If you must use syrups, use Monin, they make the best ones IMO.

Just out of curiosity, why do you think lattes with syrups will be better for you than soda? You're just replacing a sugary drink with a slightly less sugary drink with fat.

the problem with both is that they have a single point where the whole mechanism is held together. This causes play in the burrs which gives you some sloppy grinding. There are many hacks that are very easy and cheap that get around this, though.

What "number" should I put my Baratza (starbucks version) grinder on for an Aeropress?

depends on how it's calibrated. That is actually pretty popular mod to do in order to use a maestro for espresso grinding, you can change the baseline closeness of the burrs by sacrificing the coarse end.

Anyway, what "number" you should put a grinder on for anything is kind of a loaded question. It depends on the coffee, it depends on the calibration of the machine as mentioned, it depends on your personal preference within the "proper" extraction range. I would start around the medium range of whatever you would consider "fine" and work around that. Under extracted? go finer, and vice versa.

Had espresso finally at my favorite local coffee shop. They have all the right things, but it came out really bitter with almost no crema and much too bitter . What are the odds other places in town that make less-good drip coffee would have better espresso?

How spergy/nice are they? If they are very friendly and care enough, you can help them diagnose the problem. Watch them pull a shot, how much coffee they use, see how they tamp the coffee, count how long it takes to pull. Sounds like they're over extracting by not using enough coffee and not tamping hard enough, also the lack of crema is usually a strong indicator of old beans.

Thanks for the info. You're right that it's pretty minor, but the fact that no one took a look at the grinder and said "hey, wait a minute" before boxing it up and shipping it out says a lot about how they do things. There's clearly no check list, so screw ups like this are bound to happen. Not the kind of company I'd want to give a few hundred dollars to.

Regarding being covered in coffee dust, yes, it was covered in larger grinds that were stuck on by static. It wasn't terrible, but it was definitely noticeable. That said, the knowledge that they test the refurbs by grinding coffee is a reasonable excuse for this.

At this point I just want to use the loving thing and start drinking good coffee. I've been testing it out with some not-very-oily beans, and it certainly works. The more coarse grind settings are very uneven, although lacking any very fine powder. Is this typical? I'm getting some pieces that are probably a couple millimeters in length, and some that are just tiny specks. It's looks kind of like what comes out of a blade grinder. Is this typical? I'lll make some French press in the morning and report back.

How coarse are you talking about. You shouldn't be using gravel for press pot.

Not disagreeing with them, but seems a bit silly to say don't use them because of waste, when that could be applied to just about everything we consume, may as well say never buy cereal unless its from a scoop your own shop and you use your own container, or only buy ground beef from a butcher wrapped in paper because of the plastic/styrofoam container.

Waste is but one point, but sure, get fixated on it. It's just that it's wasteful, it's that they claim that they're environmentally sound, when they're not.

aside: and you really should do those two examples you listed as outlandish. They're not. Local grocery has some really good granolas in their bulk food section, way cheaper and healthier than most box cereal. But alas, I rarely eat cereal. Buying from a butcher is a better practice overall because you're supporting small businesses, you get their expertise, you can pick the cuts you want to go into your grind and the tailor the fat/lean.

Help me, goons, for I have tasted this quality coffee you so praise and... it was pretty drat bad.

Here's what I did, hope you guys can help me figure this out

The stuff I received:
- Ethiopia Shakiso beans, roasted on December 12th.
- Hario mini mill
- Kalita Wave steel dripper

I adjusted the mill somewhere in the middle position, ground 15g of beans (mug holds 250ml), boiled some water and heated up the mug. For the actual brewing, I did pretty much what this dude did: http://www.youtube.com/watch?v=EyknoezUCNg

The result? A watery mess with a pronounced bitter aftertaste. No sign of the "bucket of red fruits" or any other quality people talk about when they describe this coffee. I can still taste the bitterness, though, I guess that's something

How dark is the shakiso roasted to? Taken too dark, you could get burnt flavors no matter how you brew it. Also, the minimill can have a bit of problem with grinding coarser grinds without modification. This has been discussed a bit, but basically, the inner burrs are only attached at one point along the shaft and this causes a lot of play as you turn the crank, resulting in many large particles and fines. Modding is easy enough though, and cheap. Inconsistent grind can lead to the finer particles being over extracted, larger ones, under.

I thought bitterness is often a relation to extraction time, usually meaning it was too slow and you'd want a coarser grind. It might just seem bitter because it didn't extract enough so you're not getting the enough of the coffee flavor with it in which case, yeah, go finer.

Edit: That's also a fairly acidic coffee if I remember which might also be why it's coming off bitter. If you're not used to acidic coffees you might want to try something smoother like an Indonesian or Brazilian.

Bitterness can be related to extraction time, but can also be related to too fine of a grind, and too little quantity of coffee used. Any photography people can think of proper extraction kind of like proper exposure. Like exposure there are independent variables that can be adjusted to acquire proper extraction. These are coffee quantity, grind size, water temperature, brew time. If the brewed coffee tastes overextracted this is usually due to too fine of a grind size with too little coffee, too hot water (rarely a problem with pour over), or too long of a brew time. Overextraction, to me, tastes watery, hollow, and has a bitterness that I can best describe as "cardboardy".

The thing about acidity is also something to think about. It can be hard to decipher people's impressions of coffee as there is a such thing as a pleasant bitterness, that Bob_McBob is talking about, and a pleasant acidity (most often found in Africans and especially dry processed Africans, Kenya AA is notoriously acidy, sometimes called wine like) that rockcity is talking about. And there is such thing as bad bitterness (obviously) and sourness which can be construed as acidity.

Thanks for the help, I'll try different grinds/temps/pour methods and see how it goes.

I can't stop thinking about the watery part, though. Any thoughts on that? Maybe it's because I've been drinking espressos all my life, but this coffee had no texture at all, it was like drinking (crappy) flavored water.

Yeah, sounds overextracted. December 12th is also over a week ago, how was it stored?

Gave it another shot. I boiled the water, waited 3-4 minutes before covering the grounds, let it do its thing for 30 seconds then poured over (in a circular motion around the edge). Brew time was around 2 minutes (first time was 3+ minutes). Grind was coarser than previous attempt.

Result... is the same. Flavored water, tastes like death. I feel so goddamn incompetent

I would go with a gently caress-it opposite direction brew next time. Grind finer than the first try, use 1.5x as much coffee, and pour slow, aiming for a 4 minute extraction. The thinking here is maybe the grinds were too coarse to begin with and the water is just passing around them without actually extracting much. This is one reason I really like the CCD, it's a lot more foolproof.

Also, I was given an air popper. Does anyone have any suggestions for good "beginner beans?"
(quote is not edit)

Congrats, too! "Peaberry" type beans are nice because of their shape. They roll easily and roast evenly because of this. Also wet process coffees have a tendency to roast more evenly because of the nature of the process. The size sorting is usually more consistent and there are fewer "quakers." Coffees that can take a large swath of roasts and still taste good are good as well, as your roast control will not be optimal at first.

The Maestro is significantly better. Better burrs, more grind steps, anti static container. It is worth it.

Is there a point at which grinding your coffee right before you use it isn't going to do much to save it? My parents got like 10 pounds of coffee from Costco, and immediately put it all in the freezer. I am not going to be able to convince them to get better coffee, or put in a modicum more effort than it takes to dump grounds into the top of a Mr. Coffee in the morning. Are they going to see any benefit from using fresh-ground-correct-fineness coffee, or is that a waste of effort at this point?

Depends on the coffee at costco. The used to sell these fresh roasted 2 lb bags, single origin (SO). It was pretty decent coffee. I stopped buying roasted coffee though when I started roasting .

I'm kind of unsure of what you're asking though. I think you're asking if the quality of the coffee is so bad and all other brew variables are bad, is optimizing grind worth it? I think it depends on who's drinking it. If you are on a crusade to get your parents into good coffee but they couldn't care less, I think you're destined to fail and I wouldn't even bother. If you think they could be swayed, I wouldn't even bother with baby steps. I'd show up with a modded skerton or mini mill, some fresh roasted coffee, and a CCD and do a good coffee full assault on the senses. Then when they at the enlightening experience of a proper cup of coffee, getting them to get a 100bux grinder is a lot easier.

Edit: even if you get the cheap Costco "Jose's" brand, this coffee is still miles better than preground folgers/maxwell/yuban/whatever. I think proper grind treatment will still be noticeable.

If anything, (to my untrained eye) that looks too coarse.

I think you're starting to get too caught up in the physical aspects of the brew process. How did the coffee taste?

Coffee looks a bit coarse to me, but then again you also have a lot of sludge in there (which would have shown up in the cup had you had brewed press pot), probably from your wobbly hario. Both of these are moot when talking about your slowed drain time because the thing actually slowing your drain down is the filter. 25-40 sec of drain time is perfectly acceptable. Don't freak out. These things are only worth pursuing if you don't like how the coffee tasted. So, how did the coffee taste?

Welp, end of the line for me.

Do you ever taste other things like wine, whisky, rum, or tea? I mean taste, not just drink. These "notes" that descriptions like to brag about are just subtleties in the coffee, the coffee wont actually taste like a cup of toffee or caramel or hot chocolate or gingersnapcookies with wild berries. It tastes like coffee with a hint of fruitiness, or coffee with a caramel-like roastiness, or coffee with a rustic chocolate like earthiness, or coffee with a bright spicy nuance. These notes are just things that the cuppers, when cupping, think the coffee's subtleties remind them of.
