I’m not sold on this yet, but from reading some of the tasting notes, it appears that it may take a lot of experimentation with the time/temp/amount of leaf.
On the advice of the tasting notes, I used 2 tsp of leaf and steeped for 2 min at 160°. This produced a brew that, while initially lightly sweet, quickly turns fairly bitter and leaves an unpleasant aftertaste.
Rating pending. Going to try a second, much shorter steeping now.
