Mystery solved!
About a decade ago, as a noob tea drinker, I bought a box of Iron Goddess tea because, c’mon, how cool is that? It was some of the most delicious stuff I’d ever had. Upon going to replace it, however, the next batch was… not the same. I’ve been sampling different varieties off and on for all these years, and have gotten a lot of “meh” green tea in return. I’d pretty much come to the conclusion that the first batch was some kind of fluke, or mislabeled package.
Then I recently learned that there’s an oolong variety. I finally managed to track some down locally and, yep, this is my long-lost love. :) A bit more perfume-y than I recall it being, but this is still one of the most robust and complex “light” teas I’ve ever had.
