I have been searching for a blackberry and welch's concord grape concentrate DB recipe. (black and bruised). I have had no luck. Would someone point me in the right direction, please. I have 32# of frozen blackberries and 24 cans of concentrate. I have 3 10gal. and 1 20 gal. brute fermenters. I'm ready to rock and roll, just need the darn recipe. TIA
