2 Gallon Batch
2 pints of blueberries
6 lbs. of watermelon
4 lbs. of sugar
7 qts of water
4 tsp acid blend
1 tsp tannin
2 tsp yeast nutrient
2 crushed campden tablets (recommended)
1 tsp pectic enzyme
1 packet champagne yeast
Wash berries, cube the watermelon (you can get rid of seeds by putting watermelon through a strainer or feed mill but isn't necessary). Put it all in a nylon string bag. With clean hands, squish the fruit. Boil the sugar and poor hot syrup over the fruit and cover.
When cooled, add the yeast nutrient, acid, tannin, and include a Campden tablet. Cover and fit with an air lock. Twelve hours later, add the pectic enzyme.
Twenty-four hours later, check the PA and add the yeast.
Cover the must and stir daily for a week or so till the PA comes down to 3 to 5 percent. Rack the wine into a secondary fermenter. Bung and fit with an air lock. Rack it twice in about six months, till fermented out dry.
If you like, use stabilizer and sweeten it with 2 to 4 ounces of sugar in a syrup. Bottle. Keep for six months at least.
