I finally got a better brewing for the Tenjo and I can say I'm really enjoying it.
Unlike a lot of fukamushis, this isn't just an 'in your face umami' or 'hi ire' sencha at all. In fact, I found it brews best using near-gyokuro parameters:
5g leaf, 4oz water, using 140 - 145F water, for 1.2 mins.
2nd steep, same temp, but for 30 seconds. And you can go from there.
It is like fresh green beans, perhaps a little vanilla aroma, and very smooth. There is a nice lasting aftertaste as well. And because its fuka, no bitterness, which is not necessarily my favorite thing, but it is easy to drink. It reminds me slightly of a kabusecha, actually.
The Tenryu ultimately beats this one out, but it is still a good offering. I am very thankful to Chip and his hard work on this. This was an excellent TTI. Thanks!
