Essentially powdered tea leaves. These guys are everything I dislike about mini tuos. While the leaf quality and size was better than generic garbage-grade tuos that most tea shops not specializing in puer sell, these are still very hard to get a good cup out of. The leaves are just so small and fragmented that any heat at all instantly brings out a sharp bitterness. I normally enjoy bitterness/astringency in a young sheng, but this is far too much with very little else to offer. I think only one of several tries have given me steeps that were enjoyable, so I haven’t found myself returning to these.
With that said, these are still much better than what I’ve found from other non-puer shops. If convenience trumps all they aren’t a bad idea, just be careful to steep at lower temps than normal. I would stick to the shou mini tuos from Yunnan Sourcing however as the bitterness there is less of an issue. I need to find my notes of which specifically, but there is a 5 g mini shou tuo from YS that I actually enjoy more than many cakes offered much more expensively.
