As a coffee ages I need to grind finer and use more. I think this helps to prolong the peak period of enjoyment.
I've tried to plan for coffee always available at peak but my usage and choice of beans is just too variable. And to some extent, it's instructive and fun to experience the change over time. For example, I love to go through the wow of a shot on day 3 and the WOW of a shot on day 4. I'm convinced this experience helps me enjoy the shot even more than if I always drank it at peak. (Even to me this sound a little like that old marketing advice - if you can't fix it, feature it!)
Michael,
I have several thoughts following your questions. First, while it is abundantly clear that coffee peaks and declines it is also true that the decline is generally much more gradual that the climb to the peak. This is also true for wine. Today I had three more single shots from the Eth, Harar Ormonia. Like yesterday's these were also a step off the peak. But the change from yesterday to today was not the same significance as the step off the peak. Given the gradual decline I think one can indeed work on the variables you suggest.
I find that even without trying to slow the decline that I need to grind more finely as the beans age just to get the right tamp/flow. If one pushes these one will indeed get variables to work on. probably somewhat different for each coffee.
I will admit that I have become less willing to compromise on freshness. I "discovered" the centrality of freshness long before I had a decent espresso machine. It was my taste that drove me to ask whenever I bought from the local roaster, "What are the freshest beans today?" It was a long difficult struggle to get them trained to deal with this request. But now I take care of freshness myself by roasting.
My latest game is to roast side-by-side batches. This week it was two Ethiopians (Harar & Ghimbi). I have recently done two different Yemeni. Next week I anticipate two Brazils. In all of this I am done at 7 days and give the remainder away.
I can see your point about the instructiveness of a longer view of each batch. I think I am spoiled on following the peak.
I think the truth here is to pay attention to whatever you are doing and make it instructive. My watching only the peak and your watching the long view are both possible ways to learn.
