VR21 Mangrove Jacks Wine Yeast
A strain suitable for all styles of red wine (except high alcohol wines above 15% ABV), this moderate fermenting yeast produces well-structured, well-balanced wines with enhanced dark fruit notes and good palate length. The positive organoleptic impact of this strain allows for promoting varietal fruit expression without detracting from the natural qualities of the grape.
Suitable for for Cabernet Sauvignon, Syrah, Shiraz, Zinfandel, Grenache, Tempranillo, Sangiovese and more.
Alcohol Tolerance: 15% ABV
Usage Directions: No rehydration required - add direct to grape must and stir well. For best results, ferment at 18 - 28°C (64 - 82°F).
Storage Recommendations: Store in a cool, dry place.

Saccharomyces Cerevisiae - Exceptional strain for full fruit varietal and country red wines promoting good structure, balance and colour. The majority of yeast strains strip out fruit flavour and colour from the must, not so with VR21 which is particularly noted for preserving and retaining the natural fruit characteristic Craft Series of the grape / country fruit and enhancing palate length. VR21 is a relatively neutral strain producing subtle levels of aroma and flavour compounds, allowing full expression of varietal / country characteristic Craft Series whilst enhancing colour, wine structure and balance. VR21 is an ethanol tolerant killer strain, capable of fermenting to 15% abv. ethanol. Good production of glycerol, low volatile acid production, zero sulphur 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 flavour/aroma development.
