The first time I tried this it came out bitter. I gave it the benefit of the doubt by assuming that was probably because I had followed Adagio’s deficient brewing instructions, which say to use boiling water. The next time I tried it I used pre-boiling water (probably 180-190F; I’m really just guessing though) and it’s pretty heavenly and not bitter at all. It tastes a lot more like it smells, too, like sunshine on fields and fresh sweet grass hay and all the best hints of wonderfully oxidized tea leaves.
