You’d think I would have learned by now…
I build a mental model of the blend I want to create. I know the profiles of the beans that I’m building with — this one’s got body out the wazoo, and a soft, tannic finish; that one’s got a spicy aroma and a bit of a wild side…. I can call up a reasonably accurate taste memory of each of the beans in my arsenal — most at a number of roast styles.
I am, however, unable to construct a mental taste model of the resulting blend that jibes with the real world.
Ever wonder why artisan coffee roasters spend so much time cupping, sipping and sampling? I suspect it’s ’cause you just can’t devise a blend in your head… you’ve got to taste, taste, taste.
