It's autumn, and thoughts turn to decay. Specifically, I've been thinking about how delicate green teas are. Seems to me that, as a first approximation, Chinese greens are a whole lot less delicate than Japanese greens in the sense of how rapidly they become dull or bitter once the airtight package has been opened.
I've been thinking about why this might be, and the answer seems so obvious that ... how could it be right? Chinese greens are usually whole-leaf teas, and senchas are almost always chopped. Could that be all there is to it?
