Vintner's VR21 Wine Yeast

$3.50

VR21 is a relatively neutral strain producing subtle levels of aroma and flavor compounds, allowing full expression of varietal / country characteristics whilst enhancing color, wine structure and balance.Â

VR21 is an ethanol tolerant killer strain, capable of fermenting to 15% abv. ethanol. Good production of glycerol, low volatile acid production, zero sulfur dioxide formation and low foaming.

VRE21 is capable of fermenting between 59 – 86°F but best results are achieved when a temperature between 68 - 75.2°F is maintained, unless cold fermenting is desired for flavor/aroma development.
