Isolated from late harvest Zinfandel from Williams Selyem Winery, EnartisFerm WS is considered one of the most robust California yeast strains. It is well suited for a wide spectrum of red and white varietals and is recommended for fermentation of high °Brix juice and to restart stuck fermentations. EnartisFerm WS respects varietal and terroir characters and boosts fruit and spice expression, while contributing to both excellent complexity and structure enhancement with soft tannin extraction. It is particularly recommended for the production of high alcohol wines destined for medium- to long-term ageing
