What happens if, in a quest for a perfect shot of espresso, you actually find it, or something close? For one thing, perhaps like a fine wine, you can never be sure the next year's vintage will be as good. And your taste and preferences might change. Of course, my quest was mainly a conceit to try a bunch of coffees and blog about them. I didn't expect to actually find something so far superior to the rest. But the third bean I brought back from Intelligentsia in L.A. this July came close. Alas, I just drank the last shot.
