This is not too far from my experience with my first kyusu many moons ago. I used it for just about every tea I was drinking ... all greens, whites, and oolong.Stentor wrote:Yes, I think so. Once I had smelled and tasted the water from the used kyusus, I could detect this taste in the tea. It was not as apparent as in the water, since it was masked by the tea's flavor, but it was there nonetheless.David R. wrote:Does the tea tasted better after the wash ?
After the cleaning, this "bad" taste wasn't there, and therefore the taste of the tea was better.
I also think the tea (and water) tasted better with the new, unused shiboridashi in comparison with the used kyusus.
I also didn't clean both kyusus at the same time. I cleaned one, then compared. The clean one performed better, in my opinion.
You guys can go ahead and taste the water from kyusus that you've been using with sencha for months. Pour hot water in there, close the lid, let it sit for a minute, pour the water in a cup, smell it and taste it. Do you really like it? Compare with a new pot if you have one at hand.
I'm not speaking of the "iron taste" that comes from the clay by the way. I'm speaking of a kind of "foul" smell and taste that seems to come from whatever accumulates on the surface of the teapot's inside.
After many many uses, every tea had an odd sweet commonality that was more annoying than enhancing. Thorough cleaning did help, but this was more extreme I guess and had gotten into the clay, so cleaning helped a lot but did not eradicate it. Though I did not do the baking soda thing.
