I’m a beer maker not a wine maker so excuse the dumb question! I have several gallons of frozen homemade blackberry juice that my grandma made. She recently died and relatives have been making jam/jelly out of it but have grown tired of that. They know I brew beer so asked if I could make a wine. My question is what would I end up with if I added a packet of Premier Rouge dry yeast straight to the blackberry juice? Any suggestions on a simple wine I could produce without getting overly involved?
