Fructo is an excellent yeast to use in conjunction with high sugar grape juices that will lead to high potential alcohol yield. With an extremely high alcohol tolerance of 17% v/v, Fructo can also be used for stuck and sluggish fermentations of both red and white wines when fructose concentrations are elevated toward the end of fermentation. Fructo should be used on ripe Zinfandel, Durif, Shiraz/Syrah and other high alcohol wines.
Fructo is considered a low nitrogen consumer. When using this yeast in stuck fermentation protocols, a fermentation aid should be used to assist fructose catabolism.
