Like the Momoko, this is a flavored tea with sugar crystals in it. (These ones are lumpy instead of geometric, which makes me wonder if there’s a little of the flavor infused into the crystals and that’s why there’s a difference.)
I find I like this tea for the same reason that other reviewers didn’t: its scent, hot or straight from the tin, is strongly reminiscent of a white wine without the alcoholic bite. I don’t notice the taste of the actual tea leaves in this so much, but that may be a reflection on how well it was blended; the tea and the flavor fit together to give you something that is sweet without being too sweet, yet it has a white wine tartness which lingers in your mouth (sans the cloying qualities of actual white wine).
This is another tea where I bought some a year ago, finished it thinking maybe I’m not a fan of flavored teas like this, and then found myself wanting it again recently. It’s a flavor which grew on me over time.
