Distiller’s Yeast Highlight: SafSpirit USW-6

SafSpirit USW-6 is our top-selling distilling yeast for good reason: it’s ideal for fermenting all types of barrel-aged spirits produced from grain or malt washes, and it’s very easy to work with to boot.

Formerly known as SafSpirit American Whiskey, USW-6 is a natural choice for bourbon, rye, corn, or wheated whiskeys. It also does very well in malt and Irish-style whiskeys.

It is unfussy about nutrient and O2 levels and can be fermented on grain or in wort. Best results will be had if fermented between 68-90°F, and is characterized by a rapid rate of fermentation, thorough attenuation, low sulfur development and mild aromatics.
