I have made some wine using Jack recipe's using bottled Welches juice. But after 2 months the AC is stopped at 6%. This is the 3rd batch and each one started at 17% and dropped to 11% which resulted in only 6% AC.
It will bubble for about a month then stop. When it stops bubbling is it done with the conversion of sugar, or is it still working.
For this last batch I introduced another yeast starter at 2 months to see if i could get it going again.
I started out using 4 cups of sugar per gallon, but have sinced lowered it 3 cups.
ANY help would be great
