Gervin Wine Yeast, Varietal D Yeast (GV11) | | This yeast has two special characteristics. Firstly it produces rounder, smoother wines with outstandingly good bouquets, which tend to mature quite quickly. It is good for producing young fruity red wines. Experiments with some 10 leading brands of grapebased kits, showed that this yeast gave better results than the yeasts provided in the kits or two other selected wine yeasts. The second characteristic is its ability to metabolise up to 30% of any malic acid present in the must, again producing ethyl alcohol. Accordingly the yeast is good when country wines are being made from high malic acid ingredients such as apples, gooseberries and rhubarb. Up to 14% of alcohol can be tolerated by this yeast. It should be noted that the yeast has a rather longer lag phase than most, such that fermentation may not start fully for up to 24 hours. | | Capacity: to 5 gal |
