I prepared this as Den’s Tea’s oh-so-detailed chart instructs: 2g tea, 4oz boiling water, 30/15 second steeps. First impression: reminds me of (roasted) yerba maté or kukicha. It’s a very mild flavor, not at all bitter, but also not very tea-like to my palate. Slightly sweet, but also somewhat… dusty, in flavor? Oddly dry. The second steep is very similar.
This is interesting, but not likely to become a staple of mine any time soon. Maybe it would be a good low-caffeine option if you’re a purist who doesn’t drink flavored teas or tisanes, but I can’t really imagine the mood where I’d pick this over everything else in my cupboard.
