I think, generally it's understood as for one particular tea. Some people cultivate their pots and dedicate each pot for one particular tea, therefore they buy a lot of pots for different teas, while few others dedicate their pots based on the classification you wrote above. I myself use my pots for different teas without bounded to the classification.Solodays wrote:It is said that one type of tea should only be brew in a Yixing teapot. What exactly does it mean by only one type?
It depends on how you raise your pot and how the brewed tea tastes after you steep it in your pot. Some pots improve the brewed tea taste while others don't improve your brew at all (compare to chawan). It's what fantastic about the yixing pot. If you find one of your tea brewed best in one of your pot, would you change to other pot? and if you find out that your 'best match' pot taste funny if you brew other tea in it, would you contaminate it?
I use only old zhuni (due to my preference) which is relatively not very porous compare to other yixing clay pots thus to my tongue and nose, they don't get contaminated even I brew puerh and oolong in the same pot.
