Okay - actually I had to go to my wine book to see what it had to say - Terry Garey's Home Winemaking book. You raise a good point. Grape tannin gives a wine a dryness. Grapes comes with their own tannin supply in their skin. According to Terry, elderberries, blueberries and blackberries have extra tannins, so you might be right that raspberries have it too, but Terry doesn't say so. On the other hand, a wine which has a "bite" can be due to the amount of acid in the fruit. Terry does say a raspberry wine will have a tart taste, now I'm not sure if that would be due to the acid content, tannins, or something else in the fruit. But as I look as recipes for these fruit wines, the recipe for raspberry wine calls for 1-2 tsp acid blend, while blueberry & blackberry calls for 2 tsp acid blend. Yet when I look for tannin - raspberry & blueberry call for 1-8 tsp tannin, while blackberry calls for no additional tannin. You're guess is as good as mine. It is just from my winemaking experience that it depends on the fruit...not too much tannin. This may be different for others, we all have different taste buds. Darlene
