Fermivin® 4F9

Fermivin® 4F9 – pure breeding yeast for fruity white and rosé wines

Fermivin® 4F9 is a powerful pure-bred yeast for the production of aromatic white and rosé wines. The yeast strain is characterized by fast and reliable fermentation and supports the formation of intensive fruit aromas.

During alcoholic fermentation, Fermivin® 4F9 produces high quantities of ethyl esters and sets thioromes such as 3MH and 4MMP Free. At the same time, part of the 3MH in 3MHA transformed, resulting in pronounced tropical fruit aromas.

The yeast also releases greater quantities of polysaccharides, resulting in a fuller mouth feel and harmonious structure. This makes Fermivin® 4F9 particularly suitable for wines with yeast storage (Sur Lie).
