A friend of mine gave me 10 lbs of Black Spanish grapes. What can I do with them? I do not feel like making 1 gallon of wine with it so I guess the question is what can I blend it with. My muscadines (red and bronze) will be ready in a month. Could I make a wine with the Black Spanish and some other grape concentrate variety? I also have 7lbs of frozen Blackberries. Could I combine these together?
