On a hunch, I ordered a traditional style kyusu to replace the Hario brand glass teapot I broke.  I'm not quite sure why, but it steeps a better tasting cup of sencha.  Notably, it serves up less sediment, too, because the settled tea leaves prevent it from leaving the teapot -- the Hario's top-loading basket does not have this advantage.  Thought I'd share.  !tea #gweenT
