My very first wine I started hasnt started fermenting yet and it has been about a week. My starting SG is about 1.120, which I have read is to high. So can I dilute the wine with water to get the SG down to 1.100 and pitch new yeast in there, and do I have to re-add the yeast nutrients and other stuff I put in there. Also, will the grape juice stay good in the bucket it with out it fermenting.
