I recently reviewed “Tieguanyin Traditional-Style Traditionally-Grown” Oolong tea, as purchased from from the Tea Trekker store. In this instance I might suggest that you read that review to get a baseline.
This particular tea is similar enough in description, but all in all a better tea. It enjoys better results from multiple steepings, has a richer and more complex flavor. On the other hand it doesn’t seem to tolerate cooling in the mug very well – gets that dusty flavor – blech. Drink while warm to hot for best results!
