A07 Flagship is a versatile strain prized by home and craft brewers alike for its tremendously clean character. A07 Flagship performs well at conventional ale temperatures, but can be used in the low 60s to produce remarkably crisp ales. Due to its middle of the road flocculation, filtration or fining is required to achieve a crystal clear beer.

A traditional Norwegian Kveik strain that has an extremely wide fermentation temperature range. This strain has been traditionally used in farmhouse style beers however, due to it’s fermentation temp range can be used in a variety of beers from pseudo lagers, Belgian inspired, and hop forward beers. On the cool end of the range Loki is super clean; producing little to no esters. As things warm up, it tends to produce a huge fruit ester profile.

Kveiking [Kuh-vahy-king] noun: A blend of three Kveik strains that can produce an insane amount of pineapple, guava and other exotic tropical fruit aromas. verb: Hopefully not an Old Norse term for an activity we should not be promoting. The Kveiking blend thrives in hot fermentations when big complex ester profiles are desired. A low pitch rate can be used to drive these aromatics even higher but the brewer should ensure this low pitch rate can be combined with a continuously high fermentation temperature. If the temperature drops too low, the corresponding level of attenuation can be low, with high terminal gravities. This blend contains flocculent and non-flocculent yeast strains, therefore the clarity of the final beers produced can be variable. Use this blend for anything from new school hazy IPAs to traditional Norwegian farmhouse brews. The Kveiking blend also works well when fermenting kettle soured worts for a strong tropical fruit character.

Capri’s juicy ester aromatics, tropical flavors, and bright citrus notes emphasize the desirable qualities from the two popular parent strains: A38 Juice & A43 Loki.
Capri is a small-celled warrior fit to bring out the best of your IPAs!
Introducing Capri, an experimental Saccharomyces cerevisiae strain created in our lab by directing brewing yeast through their idle sexual cycle via fungal sporulation, designed to explore the natural bio-diversity normally off limits to brewing yeast.
The Juicy ester aromatics of A38 Juice fuse with the tropical flavors and bright citrus notes of A43 Loki creating a delightfully pleasant drinking experience.
Capri is prone to stay in suspension when in large tank vessels, volatilize sulfur early, form a tight yeast cone harvest. Try dry hopping additions with this strain for a more active fermentation.
This yeast strain is not a genetically modified organism (GMO).

Classic strain to produce French Saison where a balance of fruit esters and spicy phenols are necessary.
This yeast is an insane wort attenuator. Napoleon will destroy the sugars in your saison and farmhouse beers – even the ones in which most brewer’s strains have no interest. When all is said and done, Napoleon produces very dry, crisp beers with nice citrus aromas balanced by subtle black pepper phenols. Yeast settling times can be long, usually requiring filtration for bright beers. This strain tests positive for the STA1 gene via PCR analysis and is therefore considered to be Saccharomyces cerevisiae var. Diastaticus. This yeast strain is not a genetically modified organism (GMO).

A strain of Lactobacillus brevis. It is extremely hop sensitive and therefore should only be used in worts without hops. Lacto Brevis is a great strain for souring wort in the kettle or fermenter, prior to adding yeast for fermentation. For best performance use inoculation rates of 0.1% - 1.0% by volume of wort. Lacto Brevis will typically drop wort pH to 3.3 in 1-4 days depending on temperature and inoculation rate

A traditional alt strain, 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. This strain lends itself to traditional Berliner weisse fermentations. Kaiser is a top cropping, low flocking strain so expect long clarification times, but low or no detectable diacetyl levels.
*NOTE:*During summer months, we include complimentary ice packs with all liquid yeast orders. However, it is difficult to guarantee that the ice packs will stay frozen given transit times and particularly hot temperatures. For this reason, we recommend ordering dry yeast during summer months.
