Brewed a cup of this since I haven’t had it in a while. According to the blurb, this tea is made of “limited-edition leaves”. Marketing at its best.
It’s not a great Yunnan, and is grossly overpriced for its quality. Anything from Yunnan Sourcing that has “Yunnan” in its name will be better, and cheaper.
That being said, if this is the first and/or only Yunnan that you can get your hands on, it will give you a taste of some of what Yunnan teas have to offer. The chocolatey notes of a good Yunnan are there. It’s not astringent at all, but there is a unpleasant, almost metallic aftertaste to this tea that just shouldn’t be there.
Bottom line: save your money, buy better Yunnans elsewhere. You deserve it.
