Magic Beans (a followup post)

Read this post. Then go have a look at Wikipedia’s Coffee Preparation page.

Notice anything about it?

I mean there’s a big notice at the top so you probably should have. No sources.

This is a huge problem in the “good coffee” industry. Lots of received wisdom, lots of talking heads, lots of blog posts, lots of “how to” advice, lots of expensive equipment “required” to make a better cup of coffee than the one you’re already making, you filthy casual.

(I also have a blog post… brewing… about what drives us to keep seeking out consumer perfection, but that’s a whole other thing for another day maybe. No promises.)

Here are a few choice examples of magical, unsourced coffee making voodoo:

Burr mills use two revolving abrasive elements, such as wheels or conical grinding elements, between which the coffee beans are crushed or “torn” with little frictional heating. The process of squeezing and crushing of the beans releases the coffee’s oils, which are then more easily extracted during the infusion process with hot water, making the coffee taste richer and smoother.

Well, the first bit of that is true. There are revolving abrasive elements. After that we’re back to proclaiming truth from the mount. Little frictional heating? Releases oils? More easily extracted? Richer and smoother? Really? Got any sources for that? Didn’t think so.

Many burr grinders, including almost all domestic versions, are unable to achieve the extremely fine grind required for the preparation of Turkish coffee; traditional Turkish hand grinders are an exception.

Those inferior domestic burr grinders. There’s no way a domestic grinder could make Turkish coffee! Again, note the lack of sources. Just some guy (almost certainly a guy, who owns a fancy, expensive foreign grinder) who says something.

Blade grinders create “coffee dust” that can clog up sieves in espresso machines and French presses, and are best suited for drip coffee makers. They are not recommended for grinding coffee for use with pump espresso machines.

Do a search for “burr grinder dust” on Google as a counterpoint. Find some forum post where someone (new to burr grinders) is wondering what they’re doing wrong. The responses will be “buy a better grinder” until someone honest comes along and says “well, all grinders produce some dust”. At which point the whole thing about consistent grind size is sort of debunked. How can your consistently grinding conical burr grinder be producing dust unless it’s… not really all that consistent after all?

Some coffee aficionados hold the coffee produced [by percolation] in low esteem because of this multiple-pass process. Others prefer gravity percolation and claim it delivers a richer cup of coffee in comparison to drip brewing.

Who are these coffee aficionados? Why is their opinion (which, even the coffee aficionado who wrote this has to admit, goes both ways) relevant to the article? Even if we agree that is is, which coffee aficionados? Where can I read these mysterious differing opinions? Why can’t they agree?

The coffee prepared by this [cold press] method is very low in acidity with a smooth taste, and is often preferred by those with sensitive stomachs. Others, however, feel this method strips coffee of its bold flavor and character. Thus, this method is not common, and there are few appliances designed for it.

Is it? According to whom? Where can I read a ph evidence? Where’s the study of people with weak stomachs? Who are the “others” who think this method removes “character” and “boldness”? Of course there aren’t any because this is just some coffee priest’s incantations, not actual reality.

The amount of coffee used affects both the strength and the flavor of the brew in a typical drip-brewing filtration-based coffee maker. The softer flavors come out of the coffee first and the more bitter flavors only after some time, so a large brew will tend to be both stronger and more bitter. This can be modified by stopping the filtration after a planned time and then adding hot water to the brew instead of waiting for all the water to pass through the grounds.

This doesn’t even really make a whole lot of sense. And much like the rest of the article it’s complete unsourced.

The AeroPress is another recent invention, which is a mechanical, non-electronic device where pressure is simply exerted by the user manually pressing a piston down with their hand, forcing medium-temperature water through coffee grounds in about 30 seconds (into a single cup.) This method produces a smoother beverage than espresso, falling somewhere between the flavor of a moka pot and a French Press.

I’d like to see a source for this. I’d also love for someone to tell me, without being condescending or talking to me like I’m a retard, what exactly they mean when they say “smoothness”. Is this a quantifiable thing? Can we measure some kind of chemical property of the coffee that we can call “smoothness”? Or is this yet another in a long list of religious terms the high priestly caste uses as a code to express their hidden knowledge?

Adventures in Wikipedia

That’s right: hit the Random Article Button enough, and you come up with some pretty bizarre and fascinating articles. I present for your consideration the following:

John Gates, the Communist.

Apparently, there’s this religion called “Hinduism”.

James Alexander Gordon had something to do with ships and such.

Once upon a time, there was a war with these Dutch guys in a faraway place.

Speaking of Dutch, how about that there Friesland?

The third-largest aviation company in the world is Canadian. That’s just wierd.

Aspergers

I was doing some Wikipedian Travels, when I came across this article. Read it. I’ve met people that clearly meet all the criterion for this affliction: in fact I work with one.

Wikipedian Travels, Part 1.

I’m hoping to make this a semi-regular feature on my blog, mostly about my travels through the wonderful and terribly informative world of Wikipedia.org. Considering how I literally use it every day, I think you all might get a kick out of reading what I’ve been reading and find interesting.

First off, The Stanford Prison Experiment. If you ever need something to frighten you, this would be the article. Just the idea that we all have something within us that would cause us to act like the prisoners or guards… well, that’s just freaky. And scriptural. But still freaky.

I’ve always been a little fascinated with military history, and that includes the Royal Navy. You could seriously spend an entire day reading what this page links to.

And of course coffee, that beautiful drink. A substance without which my life would approach meaninglessness. I lie. But I enjoy a cup or two now and again. You may interpret that any way you like.
