For a stuck fermentation add ½ teaspoon of Yeast Energizer per gallon of must. Sometimes a fermentation gets “stuck,” when the yeasts slow down or stop consuming the sugars prematurely. Wine and beer makers have been using yeast, a single-celled fungal organism, to help make their alcoholic drinks for centuries. I have added yeast nutrient to the must before fermentation while the Potassium Metabisulfite was doing its work. -Matt In the more current times, since Louis Pasteur's discoveries, we have developed a better understanding of what takes place during a fermentation. He has been helping individuals make better wine and beer for over 25 years. Dean Mehrkens Thief River Falls, Minnesota Wine Wizard replies: Whoa.

Created by Digital Design Solutions, the ability to ferment at cooler temperatures (wild yeasts in our climate tend to cut out below 60º F), the production of more granular, less easily disturbed lees, the ability to withstand higher levels of SO2, metabolizing a greater amount of malic acid during fermentation, bringing out more floral or fruity characteristics, greater efficiency to ferment to higher levels of alcohol. Some winemakers actually use this method calling it “wild” or “native” or natural fermentation. Dean Mehrkens Thief River Falls, Minnesota Wine Wizard replies: Whoa. The yeast strain you use will determine the style of wine you create, as well as the characteristics that the wine may take on.
