Super High Gravity yeast from White Labs is a strain of yeast from England that has an amazingly high alcohol tolerance of 25%! With such a tolerance, this yeast can be used to tackle the biggest beers, and to restart stuck fermentations in big beers which standard yeast strains may fail to fully attenuate. With an increase in gravity comes an increased rate of ester production. As with any high-gravity beer, extra oxygenation and yeast nutrition can help this yeast to perform to its fullest potential. Super High Gravity yeast is great for Russian imperial stouts and barleywines, but can also be used on lower gravity beers.


We include complimentary ice packs with ALL liquid yeast orders (if required), but cannot guarantee that the ice packs will stay cold during transit, and thus the yeast can potentially be exposed to hot temperatures. We highly recommend ordering dry yeast during the hot summer months or if you are ordering from a warmer climate. Many times during the winter an ice pack is not needed so we make the determination based on current temperatures and the destination!
