Funny thing, I have the tasting kit lying here since several months but haven't touched it yet.
Anyhow, I just got a very weird sensation from a tea: Its a tickling in the mouth and a slightly burning sensation, but not like from Chili, more "soapy", like if you get deodorant in your mouth. (No, I don't do that on a regular basis, but it happens
The feeling seems to coat my mouth and lasts quite long. I've been wondering whether I was imagining things, so I left the tea and did something else, including lunch, and then tried another infusion. And now its very obvious: The feeling returned and its quite obviously, not very subtle.
Its from a Pu from the year 2002, actually not too cheap, almost 100$ the cake from a reputable vendor. I don't know, maybe its the water filtering cartridge is doing crazy things or theres something in the tab water which I'm using, but that didn't happen before.
I'll do some more testing tomorrow to see if I can verify this.. but until then - did someone else experience this before?
