Trying to bottle some mustang grape wine and it is unpleasantly sweet. With sg’s of 1.050 to 1.070. I would think it didn’t ferment but all 4 jugs I was cleaning out airlocks on regular basis from vigorous fermenting I would guess. I have another 5 gallon jug that taste similar that I did a different recipe all together with another crazy sg. Any ideas? Should I restart all these?
