I purchased a pack of teabags of this from the store in San Francisco because I really love blueberry teas. Admittedly, I had no idea was cassis was, but the smell was what won me over. After initially brewing for 3 minutes, I found the flavor to not be strong enough and fell a little flat. The second time I gave it 5 minutes and flavors came out much better but still unlike the smell out of the bag (like others have mentioned). I found that adding a bit of sugar helped bring out the berry flavor a bit more. Though a touch disappointed by the smell/taste discrepancy, I still enjoyed this tea.
