Fermentis SafSpirit USW-6 Distiller Yeast 500 g

Fermentis SafSpirit USW-6 is a distiller yeast made for grain ferments and American whiskey style washes. It works well with corn, rye, wheat, barley, and blended grain bills where you want reliable fermentation and a profile suited to aged grain spirits.

The 500 g pack is larger than a single home batch, so it is best for hobby distillers who plan to make multiple 23 L washes. For a typical 23 L batch, use roughly 7 to 12 g, depending on starting gravity, grain bill, and fermentation conditions.

USW-6 is listed for use around 20 to 32°C and has very high alcohol tolerance. For home batches, a steady fermentation temperature and proper mash conversion will do more for results than simply adding extra yeast.
