Cuz What garymc said plus: I had enough pounds of grapes to end up with 4 gallons of wine, I wanted 5. The original must was a little high on acidity.. So I added 1 gallon of water, and 5 pounds of fresh elderberries. The elderberries are high in tannins and low in acid, my overall acid came down to like 3.5-3.6 and I ended up with a wine that people like with strong tannic structure. Elderberries are the one fruit that will give a wine similar too, equal too or better than grape wine. Elderberries are much overlooked and I would say it is a wine that merits an addition in every home cellar. My opinion is that while dried fruit is an excellent additive in and of itself, it adds an oxidized taste. But dried elderberries can make an excellent beverage
