Sadness! I’ve tried this twice so far using my Zarafina, and I never got the caramel taste. Instead, I got smokiness—almost like the black tea version of Shanti by The Simple Leaf. The cup I made at the “green” Zarafina setting was not bitter at all and went down easily without sugar or milk—a rarity for me. I didn’t get to taste the tea made at “Oolong” setting until 5-6 hours after it had been brewed, and it was cold and super bitter (there was a lone tea leaf in my mug, so maybe it kept steeping).
Sigh. I need a thermometer, I guess.
