I tried the tea bag sample of this last night.
I have no real experience with gyokuro (though, I’ve been intending to try it)…the only time I’ve had something like it was not great (Gyokuro blend Sencha by Yamamotoyama… I don’t recommend this really).
Like others mentioned, the flavor wasn’t very strong. I used 4oz of 160 degree water, and steeped for 2 minutes. While it did have some watery flavor, the tea flavor was excellent. Pure sweetness and an aftertaste that was also a little sweet but filled the mouth. For a teabag, this was really good tea (and got multiple steepings)… I would buy this if I found it in the Japanese store and wanted to get a good quality tea in bags.
