ScienceOnline'09: Liveblogging Coffee Cupping at Counter Culture Coffee.

Counter Culture Coffee generously invited us to join us for their regular Friday morning cupping at their Durham, North Carolina headquarters.

Here are the dimensions on which the coffees are evaluated in the cupping:

• Fragrance:

smell of coffee when it's dry (undertones, first thing that comes to mind)

• Aroma:

smell off coffee just off the boil (under 200 ^oF)

• Break:

Crust forming on top from brewing -- from CO₂, unless the beans are stale. After coffee has steeped 4 min, breaking crust of coffee and smelling it.

• Brightness:

acidity that bring their own flavor (cf. acids that distinguish a banana from a lemon)

• Flavor:

how it tastes (slurp vigorously)

• Body:

tactile sensation of coffee (cf. skim milk vs. whole milk)

• Aftertaste:

the flavor that lingers 30 sec after drinking the coffee

We're doing a blind tasting, so our reaction isn't biased by our past history with a particular variety. Also trying to work silently so as not to influence our neighbors' answers .

Tegu (Nyeri, Kenya)

All the coffees we tasted today were wash coffee (take skin off fruit, let it ferment awhile, then wash it).

Coffee never better than when it comes off the tree.
Each step of processing is a chance to mess it up.
A lot still to be learned about how microclimate in which the beans are grown affects flavors.

It's very odd to take so much time trying to discern all the flavor notes of a beverage that many of us use as our morning jump-start. For many of these, I'd find myself saying, "I know that flavor (or smell), but can I name it? Also, it's worth noting that we were tasting little bits of the coffees with spoons, rather than quaffing mugs of it ... which is kind of what I feel like doing right now!
