Traditional Alt yeast strain however, this German ale strain can do just about anything. Kaiser is ready to produce an array of German-style beers. It will keep the beer clean and allow the delicate malt flavors and aromas to shine through. Characteristics of this strain make it a good choice for traditional Berliner Weisse fermentations. Kaiser is a low flocking strain, so expect long clarification times, and very low diacetyl levels.
