4F9 (Fermivin)
Fermivin® 4F9 produces a wine with very intense, mainly exotic fruit aromas.
Fermivin 4F9 releases large quantities of polysaccharides. It is therefore especially recommended for making white wine aged on fine lees. This yeast is for winemakers who want to improve the wine’s body and volume.
Fermivin 4F9 can be used for secondary fermentation in closed tanks (Charmat method).
Fermivin 4F9’s fermentation ability can be improved by optimizing its nitrogen nutrients. Adding autolyzed yeast Natuferm® promotes the production of fermentation esters. Adding the nutrient Maxaferm® improves resistance to difficult fermentation conditions.
