SafSpirit™ M-1 Fermentis by LeSaffre Yeast is the most famous and almost inevitable strain for producing Scotch and single malt whiskies. Produces great congeners, suitable for the aging of the whiskies in barrels.

Good alcohol resistance (over 15% v/v). Very good attenuation due to the assimilation of complex sugars, making it the best option for whiskies produced from malt, when enzyme additions are not allowed. Good choice for continuous fermentation.
