For cool climate aromatic white varieties.
UVAFERM GHM™ was isolated by a team led by Professor Manfred Grossmann at the Geisenheim Research Center. This is a yeast for aromatic white wines for cooler regions. Numerous fermentation trials with UVAFERM GHM™ yeast in Riesling and other aromatic white varietals from cooler regions resulted in consistently harmonious and well balanced wines. UVAFERM GHM™ has the ability to enhance floral aromas, whilst avoiding strong ester production. It brings harmony between bouquet and the delicate fruit aromas as well as maintaining a refined acidity, important in such varieties as Riesling. UVAFERM GHM™ is particularly suited for white wines destined for extended lees contact.Fermentation Speed
