(Most likely it's just a sub-clinical Obsessive-Compulsive Disorder manifestation...)
Several years ago, a friend observing me taking a long time prepping and making a single small cup of coffee, said "you sure must like coffee" -- irritated the hell out of me but I replied civilly "The journey is the reward." But he did make me think about why I had my nightly ritual of grinding, swearing, tamping with the broken Cremina tamper, cleaning up, pulling a double, thinking "wow, there's some crema there" and tasting, cleaning some more, grabbing the cup of slightly cooled espresso -- a very small cup. Now I have to admit that if the initial taste is wonderful, I taste more before cleaning up.
Still, all I have is this little cup of reasonably good coffee with varying amounts of froth on top -- if I'm lucky. But if I started to think about the payoff ratio, I'd always tell myself "remember, the journey is the reward; every life needs a discipline to make it worthwhile...." Then I finally, after 15.5 years, I "girded up my loins" and, with Steve Robinson's invaluable tutorial, rehabilitated my Cremina.
You know the routine: "damn, looks like I need a better grinder; gotta get a 'real' tamper; those Bodum double-walled glass cups sure look pretty in the espresso porn shots, ..." Done. The trouble is, my average shot now is indeed better than in the old days, but the mythical godshots haven't appeared once, while the old setup would occasionally, accidentally, produce one. And the new setup takes considerably more time than the old.
So I'm thinking again about the payoff ratio. And I'm remembering the 34 years I taught experimental psychology and all those old rat studies. Partial reinforcement, reinforce the little beasties with a rat pellet only occasionally (and unpredictably) when it presses the lever and it will continue pressing that lever much longer when it no longer pays off than if it were fed every time it pressed.
Actually, I did get a hint of a godshot once with the new setup, but I don't know how far I can push the variable partial reinforcement schedule before my lever pulling behavior extinguishes.
Now comes the sneaky point for this thread: maybe I need new roaster connections. I arrived in the Berkeley area in 1966, a few months after Mr. Peet started his small shop where he roasted his beans onsite. Soon I was buying freshly roasted beans there, enjoying that wonderful smell in the shop if he'd recently roasted -- and sometimes on Saturday morning, the smell of roasted peanuts if he were in the mood. I was hooked.
But I'm also stuck, thinking Peet's Coffee is still that little shop when it actually has over 80 stores now, with centralized industrial roasting plants. Most likely the Arabian Moka Java I've always used in the Cremina is not the same as it was in 1991 when Peet's had only a few local stores. Probably the freshness and quality of their beans declined so slowly over the years that it was imperceptible, resulting in my thinking the problem was with the machines and my techniques rather than the coffee.
But even with the best possible roasted beans, I'm pretty sure that "the journey is the reward," along with the partial reinforcement effect, will still be involved -- along with more than a modicum of OCD.
