Go-Ferm is a product used in the winemaking process to help promote healthy yeast growth and fermentation. It is a nutrient supplement made from a blend of vitamins, minerals, and amino acids that are essential for yeast growth and metabolism.

When added to grape must (juice, skins, seeds and stems) before the start of fermentation, Go-Ferm helps to nourish the yeast and create an optimal environment for fermentation. It provides the yeast with the necessary nutrients to start fermenting quickly and efficiently, which can result in a more consistent and predictable fermentation.

Go-Ferm also helps to protect the yeast from stress during fermentation. It can help yeast to survive the high alcohol and low nutrient conditions of the later stages of fermentation and also help them to survive the high acidity that’s present in some musts.

Go-Ferm is a dry product that is typically added to the must in the form of a rehydration solution, which is made by mixing Go-Ferm with water at a specific ratio before adding it to the must. Go-Ferm is also available in a liquid form, which can be added directly to the must.

In summary, Go-Ferm is a yeast nutrient supplement that is added to grape must before fermentation to promote healthy yeast growth and fermentation. It helps to create an optimal environment for yeast and protect them from stress during fermentation, resulting in a more consistent and predictable fermentation.
