I’m going to try this again. My first date with Blueberry Cocktail was disappointing. The hibiscus taste (or at least I think it is hibiscus) runs away with the whole gestalt. There are ample blueberries in the dry tea. Plenty of blueberries! And yet, perhaps, the other components overwhelm the blueberry.
For me, the hibiscus comes across as a loud and brassy citrus-y note, but without the clear flavor of an orange, grapefruit, lemon, or lime.
