Isolated from a Belgian-inspired brewery in the Northeastern United States, this single strain of Brettanomyces bruxellensis exhibits good attenuation and produces a tart tropical fruit ester profile reminiscent of SweeTarts™.

Isolated from a unique mixed fermentation beer produced in the Midwestern United States, this Brettanomyces bruxellensis isolate exhibits a mild tartness and soft funk with a solid backbone of tropical fruit esters (papaya, guava, pineapple, guinep). This strain is highy active and produces a thick krausen.

Amalgamation II is a blend of 5 Brettanomyces bruxellensis isolates that showcases qualities of each isolate: The lemon tart and restrained funk of the Beersel isolates and TYB184, the SweeTarts™ character of TYB207, and the tropical bouquet of pineapple, guava, mango and papaya esters of TYB261.

Oud Vat Brett is a single strain of Brettanomyces bruxellensis isolated from a spontaneously fermented beer aged in a specific large format wooden Vat, known for its complex Brettanomyces-derived character. This fast acting strain produces a mixed dark berry quality with earthy undertones and a thick krausen.

A blend of three strains of Brettanomyces bruxellensis that imparts a complex array of tropical and dark berry fruit esters. All three strains in this blend are quick to grow and develop character, highly versatile, and can be employed in primary fermentation, extended aging or bottle conditioning to quickly develop complexity in any mixed fermentation beer.

Metschnikowia reukaufii is a nectar specialist that was isolated from flowers in the Berkeley Hills of California. Evolutionarily, these yeast evolved to produce a more odorous and attractive nectar for pollinators by enzymatically altering otherwise inodorous nectar compounds including glycosides. While only attenuating to 20-25% in brewer’s wort and not utilizing maltose or maltose derivatives, in malt-based co-fermentations it has been shown to drop gravity and pH of the fermentation faster, accentuate and modulate the flavor and aroma profile and soften the perceived bitterness of the finished product.

This is a single strain of Brettanomyces bruxellensis isolated from a California brewery that utilizes a diverse array of organisms in the production of their eclectic beers. This strain exhibits a lemony-tartness with hints of hay and mild funk, and has a crisp and dry finish.

PurePitch® Next Generation (an evolution of White Labs’ PurePitch®) delivers great shelf life, and provides a commercial pitch rate for homebrewers. 

This isolate is a single strain of Brettanomyces bruxellensis hailing from a brewer of all things sour and wild in the Mountain West. This strain exhibits a strong profile of complex tropical fruit that is dominated by pineapple with a noticeable earthiness. This strain is highly active and produces a thick krausen.

This blend of lactic acid producing Lachancea thermotolerans isolates is unique from any yeast we’ve ever isolated. In addition to creating an acidic character that is much more complex, multi-dimensional and reminiscent of a traditional long-aged sour as compared to a kettle sour, the attenuation, pH and ester profile are precisely tuneable based upon the percent of fermentables as glucose.
