So I tried the rest of the sample today with steeping parameters that I’ve typically used at work, for the Genmaicha from 1TTEN (170 for 30 seconds for the 1st). Because I brew it at work, the hot water I get comes from our water cooler at a steady 170.
This brought out the same flavors in Satsuki as 1TTEN’s version (toastiness, good but somewhat unremarkable, followed by a most sweet, aromatic, mouth-filling aftertaste), further reinforcing that both of these are great teas and very similar in quality.
