A while back I made a 5 gallon batch of blackberry wine using Vintner's Harvest Blackberry Fruit Base. In my opinion, 1 gallon of base to 4 gallons of sugar water makes a very weak tasting wine. I'm trying to decide what to use to increase the blackberry flavor. I'm thinking I may just add another gallon of Vintner's Harvest Blackberry Fruit Base. Has anybody else tried this, or had similar experience with weak flavor?
