Had this tea at work a couple days ago; we carry a lot of the Tazo teas for some reason. I saw the hibiscus in it, and I knew it was going to be astringent, so I steeped it a little less. Somehow, it didn’t affect the level of astringency in the tea. It smelled amazing though. I could still taste some of the other herbs in the tea, even though the astringency pretty much dominated. If I had added some sugar, it would have probably cut down on the bitterness though. I’ll definitely do that next time.
