Cablecar for Imperial Organic Yeast is THE strain for making a California Common! It ferment crisp and clean even up to 65F, producing beers that are very lager-like. Of course, it can also ferment cool, down to 55F. It flocculates well, producing beers that are very clear with little effort. California Common is the style that this strain is most often used on. However, it can also create wonderful pseudo-lagers for those without precise temperatures control.
