Fermivin 4F9
FRUITY ROUND WHITE AND ROSÉ WINES
Purpose
Fermivin® 4F9 is a strong fermenter yeast that produces fruity wines with tropical fruit notes and a good mouthfeel. It produces high levels of ethyl esters, releases thiol aromas (3MH and 4MMP), and efficiently converts 3MH into its acetate, 3MHA.
It releases large quantities of polysaccharides and is therefore especially recommended for ageing on lees, giving well-balanced and round-tasting wines.
As a strong and resistant yeast, Fermivin 4F9 can be used for secondary fermentation in closed tanks (Charmat method).
The addition of autolysed yeast like Natuferm® Bright promotes the production of fermentation esters and thiol aromas.
