In the news today, researchers in Australia have decided to take a deconstructionist’s approach towards creating the ideal coffee: Australia Looks To Produce The Ultimate Cup Of Coffee | Gov Monitor. The Rural Industries Research and Development Corporation (RIRDC) performed experiments to determine how picking coffee cherries at different stages in their maturity might affect their taste in a resulting cup.
From the article:
Researchers taste tested a range of roasted coffees which had their cherries harvested at different stages of their growing cycles. Their aim was to determine when is the best time to harvest coffee cherries in order to achieve the tastiest cups of coffee for the growing espresso market and the traditional plunger market.
They rated the coffees according to five criteria; sweetness, balance, body, flavour and aftertaste.
We applaud the intended goals of measurement-driven thinking in their research, even if we’ve previously debunked the confusion between measurement and science for people tinkering with coffee. However, we also cannot help but feel that the RIRDC’s approach is loaded with the self-deceptions of food science deconstructionism. Another example of this deconstructionist approach being nutritionism.
The big problem with deconstructionism is that it presumes the superposition principle. In less geeky terms, this means assuming that nature behaves as if everything you can isolate is completely independent from everything else you can isolate, and that nature follows a simple sum of all the parts. This is a naïve belief because biological systems are highly interdependent. For example, vitamin D is added to most forms of dairy milk because our absorption rates of vitamin D are much poorer if we take it separately — i.e., without milk.
Similarly, what might give coffee a better body might also adversely impact its brightness or flavor (and does, in fact). Is it any wonder why coffee blending is more of an art than a science?
I Write, Therefore I Am A Barista
In the less geeky news department, we have this post from the Seattle Times‘ regular “Coffee City” columnist, Melissa Allison: Business & Technology | Coffeemania — from the mouths of baristas | Seattle Times Newspaper.
In true tyranny of the barista fashion, Ms. Allison offers several short interviews from coffee industry notables, from Tonya Wagner of Victrola Coffee Roasters to David Schomer of Espresso Vivace to author Michaele Weissman. With her lead-in of, “We’re going behind the counter to ask baristas to talk about themselves,” clearly we have several people who either currently aren’t or never have been professional baristas.
Must we always presume that anybody doing anything for quality coffee in the industry must be a barista? Is there any better way to simultaneously lowball the qualifications of a barista while grossly oversimplifying how good coffee arrives in our cups?
