Weihenstephan yeast is the classic German wheat beer strain and is used worldwide to produce Hefeweizeins, as well as other weizen and weissbiers. These beers are famed the world over, and as such, are produced in many countries across the globe. This is the perfect strain to use in the production of such beers, as distinct banana esters and clove phenolics are produced by this strain. Production of these compounds can be manipulated through controlling fermentation temperature; a cooler temperature will produce a beer with less banana esters and will allow clove phenolics to dominate, while a warmer temperature, as well as lower pitching rates and a higher wort density will increase ester production. Wyeast has stated that ove-rpitching can nearly eliminate banana character in the finished beer. While this strain will produce a significant amount of sulfur, this will usually dissipate with conditioning. This beer is a very vigorous fermenter, and as such, a lot of headspace and/or a blowoff tube are recommended when fermenting with this yeast. Try this strain when making flavorful, traditional German wheat beers, and you will be pleasantly surprised at the results!


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!
