These strains are selected to complement the varietal character of the grapes and the specific winemaking style. Wine yeast is known for its ability to ferment quickly and efficiently, converting sugar into alcohol and CO2. It is easy to use, simply add it to the must (the mixture of grapes, water, and sugar) and let it do its work. Wine yeast is an essential ingredient in winemaking; it can help to create a stable and predictable fermentation with a clean and balanced final product.
