Tried this again with 2 teaspoons in my gaiwan (I prefer it a bit stronger), starting at 3mins. Resteeps were 3:30, 4, 4:30, 5, 6, 7, and 8 (so 8 steeps total). On the last steep, my husband had just come home from work and tried it out. He was pretty surprised it was the 8th steep and still flavourful (although at this point I can taste the water more than anything).
I have to say that this one has really grown on me, and the resteeps have a nice spectrum of flavour. Like Jin Die, I think it’s a must to resteep this all you can. I’m looking forward to trying this with the same settings next time, and to write down the notes of all 8 steeps. Today I was just trying to enjoy it, not worrying about writing down the tasting notes. ;)
edit: Forgot to mention that this is a black tea, which is why the extra steeps impressed me.
