I have a small tea tray next to me at work (a school), and desk drawers full of small jars and cakes of tea. It seems rather mysterious to many students, some of whom want to try the teas and learn to manage the gaiwan, which perhaps inspires a life-long tea odyssey.
Ratings:
95+ are teas I want to have on hand and buy again. I am willing to pay a higher price than my usual threshold.
90-94 are teas that I highly praise and recommend, and they are welcome additions to my collection. I could buy them again.
80-89 are teas that I am thankful for trying, but I would keep searching for other teas before buying again.
79 or less is indicative of a disappointing tea for me.
