Had a sampler of this and compared it directly to Shin-ryoku. I don’t always like giving a review after just a sample, because if I messed up the brewing parameters (or more likely, if I haven’t found brewing parameters that I like with that particular tea through experimentation, which I can’t obviously do with a sample), I won’t get a very accurate idea of how I like the tea and how it compares to others.
In order to compare this and Shin-ryoku fairly, I did a blind test, and used the same parameters (3 oz @160 F, 2 grams tea, 90 seconds).
This came out with hints of sweetness, a little (just a little) bitterness, creaminess (yes, like delicious whipped cream without the sugaryness), and a little astringency. I think this would do even better at a lower temperature for the first brewing, so I’m going to try it (when I get a full bag) at 140 or iced-brewing and report back.
