Our #1 Best-Selling Yeast! Famous for clean flavors, balance, and the ability to be used in almost any style Ale. It ferments dry and has a very nice, soft malt flavor. We would say that it puts the flavor emphasis on the malt and hops. Definitely one of our top favorites, and MoreBeer!'s best selling yeast! To ferment this yeast properly pitch at 62-65F and let it rise to 66-68F. Ferment for 10-14 days in the primary. This strain can be used in all ales because of its clean crisp character it produces. Cal ale can also be used to help finish a beer's stuck fermentation.
