Versatile, High-Tolerance Yeast for Robust Wine Fermentations

Mangrove Jack’s SN9 Wine Yeast is a general-purpose strain renowned for its robust fermentation capabilities and relatively neutral sensory profile. This fast-fermenting yeast is highly resilient, tolerating challenging fermentation conditions and alcohol levels up to 18% ABV, making it ideal for a wide range of wine styles.

SN9 is particularly suited for fortified wines, high-alcohol wines, perry, mead, vegetable wines, flower wines, and more. Its neutral flavor profile ensures that the natural characteristics of the fruit or must are preserved, while its high glycerol production enhances mouthfeel and body without introducing unwanted flavors.
