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.

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.

This blend contains two saison-style STA1+ Saccharomyces cerevisiae isolates and two strains of Lactobacillus brevis. The Saccharomyces strains create a delightful ester profile of grapefruit and orange zest accompanied by a mild earthiness and spiciness, while the Lactobacillus strains produce a balanced acid profile. This blend exhibits high diastatic activity.

TYB282 is a single strain of Lactobacillus brevis isolated from an unintentionally soured golden ale produced by a Mexican craft brewery. This strain produces a nice, clean lactic acidity (down to ~pH 3.2) in unhopped wort within 36 hours at a temperature of ~72-77 °F. The higher the temperature up to 90 °F, the faster the acid production. While this strain can be used for kettle souring, it really shines in acidification during extended aging due to its hop tolerance (15-20 IBU).

The Lactobacillus Blend is comprised of one strain of Lactobacillus plantarum and two strains of Lactobacillus brevis. One of the strains of L. brevis was isolated from an unintentionally sour hoppy blonde ale from a Mexican craft brewery, and exhibits strong hop tolerance (15-20 IBU). Ideal for broad spectrum acidification, from kettle souring to extended aging. The higher the temperature up to 90 °F, the faster the acid production.

Mélange is made up of a rich diversity of fermentative organisms, intended for use in the production of sour beers where a perfect balance of esters, earthiness, funk and sourness is desired. This blend contains two Saccharomyces cerevisiae isolates, Saccharomyces fermentati, five Brettanomyces isolates, two Lactobacillus brevis isolates and Pediococcus damnosus. This blend exhibits high diastatic activity.

This yeast was isolated from the thought to be extinct Pure Nacional variety of cacao. In 2007, this rare variety with white beans was rediscovered in the remote Marañón River Canyon in Peru. The fruity, phenolic, and wild-like characteristics of this strain make it an ideal choice for farmhouse and saison-style beers.

This culture is a blend of a clean Saccharomyces cerevisiae strain (Germany), a healthy dose of Lactobacillus brevis (Mexico), and a touch Brettanomyces (Belgium and US). This culture ferments to a crisp dryness and produces the trademark Berliner Weisse lactic acid backbone, with a touch of Brettanomyces tart citrus character and funk.

Species: Brettanomyces bruxellensis

Profile: This strain of wild yeast was isolated from brewery cultures in the Brussels region of Belgium. It produces the classic “sweaty horse blanket” character of indigenous beers such as gueuze, lambics and sour browns and may form a pellicle in bottles or casks. The strain is generally used in conjunction with S. cerevisiae, as well as other wild yeast and lactic bacteria. At least 3-6 months aging is generally required for flavor to fully develop.

Metric Temperature Range: 15-24 °C

Flocculation: Medium

ABV: 12
