I had read a couple of wine making books written in the 70's. I've got a 5 gallon bucket nearly filled. The recipe:
12 lbs. blackberries
1 10 ounce box of raisins - chopped
8.50 lbs sugar
3.5 Gallons water
3.5 tsps. yeast nutrient
4 tsp acid blend
2/5 tsp potassium metasulfite
1 3/4 tsp peptic enzyme
Packet of Lalvin K-1 V1116
I goofed up somewhat at 1:00 in the morning I thought I was putting in the acid blend and then I realized that I must have put in the peptic enzyme instead so I went ahead and only put in 2 tsp of acid blend as I thought I was putting in acid blend but I'm like 95% sure it was peptic enzyme, I guess there is too much peptic enzyme in it, but it seems to be doing okay. The only way I had to test the acid was the strips which I understand could give a false reading.
The author of one of the books advocates that fruit wines are improved by reducing the fruit content in relation to the sugar and water. He recommends that except for grapes and apples that you use only 2 to 4 pounds of fruit per gallon. This book is 'The Art of Making Wine' by Stanley Anderson.
