Purchased first 6 gallon Merlot juice and ran to a couple issues. I heard from my local wine store that you should stop the wild yeast from fermenting with sulfites and and in your own yeast. First off it read 1.100 on my hydrometer when I first tested it. When I added the sulfites to stop fermentation the hydrometer read 1.060. So I stirred in the sulfites waited the recommended 24 hours (actually about 30 hrs) added the new yeast. Waited 48 hrs and nothing. Contacted the local wine store and they said to add yeast nutrients, done that 48 hrs nothing. What can I do to get the fermention started again.
