We need better sieves. Tea-balls are awful, and the vast majority of tea sieves are these tiny little mesh buckets that affix to the top of the kettle, meaning they only even touch the water if the kettle is completely filled. Then, to boot, they are so woefully undersized (probably for the sake of making them easy to fit into the pot) that the tea leaves barely have any place to bloom. The result is a very weak tast…
Unfortunately, finding a good quality kyusu in the US isn't so easy. Daiso used to stock them, but they seem to have stopped.
