Fermentis SafSpirit M-1 Distiller Yeast 500 g

Fermentis SafSpirit M-1 is a distiller yeast selected for grain-based spirits, especially malt whisky, Scotch-style whisky, and other barrel-aged grain spirits. It is well suited to malt washes and grain mashes where fermentation character can support the finished spirit after aging.

This 500 g pack is sized for repeated use, so most home distillers making 23 L batches will only use a small amount at a time. For a typical 23 L batch, use roughly 12 to 18 g, depending on gravity, recipe, and fermentation conditions.

M-1 has good alcohol resistance, with Fermentis listing it at over 15% v/v, depending on the process. It performs best around 20 to 32°C. For whisky-style washes, keep fermentation steady and avoid pushing temperatures too high if you want a cleaner base for aging.
