Fruity early-drinking red wines.
Purpose
Fermivin® E73 produces fruity, balanced wines for early drinking.
As a cryophilic strain it is especially suitable for fermenting must that has undergone cold pre-fermentation maceration.
Fermivin E73 can be added during pre-fermentation maceration for better multiplication.
Especially recommended together with the maceration enzyme Rapidase® Extra Color for optimal extraction of colour and polyphenols.
