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.

An excellently versatile and delicious strain for brewing a wide variety of ales and IPAs.
The newest member of our Imperialis (I-Series) yeast strain family was developed for its excellent attenuation, prompt reduction of diacetyl, and versatility brewing a wide variety of ales and IPAs. Our lab created this new Saccharomyces Cerevisiae strain by isolating two unique strains, resulting in a hybrid that is an efficient and highly flavorful agent for fermentation. It boasts a robust flavor profile of ripe tropical fruit, strawberry, and lychee that beautifully complements big hop additions.

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

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.
