It definitely will. After a couple years of experimentation and testing I've found anything over ~200F is basically undrinkable. It took me so long to figure this out because there were a lot of confounders -- I drank a lot of tea over the holidays back home, and while my parents' town is on the same water source I swear their florination is different, in a way that changes the mouth feel of the tea. I also had a new faucet installed and the galvanization in the new fixture left a strange aftertaste that took some time to track down. It was so bad that I seriously wonder how people can drink things that come out of Kohler faucets. Finally, I had some new mugs that were also causing problems...turns out the were only fired once? I'm not really sure how to describe it but it was kind of like drinking tea out of a soda can. Anyway, I eventually controlled for all this stuff and about 190F is the sweet spot. It's kind of embarrassing how much of an odyssey this all turned out to be, What works for other HNers?
