For 5 gallon of blueberry wine it takes two and one half gallons of berries,12lb of sugar and 5 12oz.cans of frozen grape consentrate and one pack of yeast.Smash berries and add 2 cans of grape consentrate and one pack of yeast and ferment this for 5 days,stiring this everyday.Then strain off the juice,desolve sugar in luke warm water and add rest of grape consentrate and put in jug and put on airlock.I make it this way and turns out great.Do not add any other ingredients to this.
