For years I've been using Montrachet yeast fo my blueberry wine and (in most cases) have beed disgusted with having to re-start it. I believe it's partly my fault forattempting to keep thealcohol level of the must as high as I could. Usually about 13 1/2%. I may be better off with a Red Star yeast that will tolerate a higher alcohol level but I wasn't sure which one to use. It suddenly dawned on me that there are many experts out there that could help. HELP!
