Some of my in-laws are crazy for them, you can keep them forever, and they are like currency, as far as I can understand. But the taste is just not really what I like. When I want to avoid caffeine I drink GABA tea, or western beauty... funny, I also have something going with tea pots, many I have owned for the past 30 years, but from time to time I still buy.. I usually buy the locally crafted, here in Taiwan in a town called Yingue, very famous for it's pottery.
My favorite tea cups are Japanese from Kutani.
Ahhh!! Tea..
Another rabbit hole😂, thanks for sharing your story with me, and enjoy your tea drinking and tea pot collecting, those are grear habits.
