New strains of wine yeast are continuously being isolated and adopted by commercial vineyards and winemakers but, as with so much regarding winemaking, they remain a closely guarded secret.
Vintner's Harvest entered into an exclusive yeast strain screening program with a leading yeast and ingredient supplier to the European commercial winemaking industry. This program considers only specialist wine yeast strains used commercially in Europe and identified a complete wine yeast range for all varieties of Grapes and Fruit. The screening process involved 3,000 separate fermentations over a two year period.
