More About Bootleg Biology Sour Weapon P Pediococcus pentosaceus Blend

Source: Cultured from Malted Barley starter and Nashville-area flowers.

Bootleg Biology is excited to release their first 100% Lactic Acid Bacteria souring blend. They chose this specific blend because of its ability to sour quickly and cleanly at a range of temperatures, and due to its mild hop tolerance.

While not “yeast”, this culture blend of two unique strains of Pediococcus pentosaceus is part of their LYP collection because it was sourced entirely from the wild: an anaerobic malt starter, and flowers from Murfreesboro, TN given to them by their good friend Art Whitaker.

Perfect for quickly acidifying unhopped wort for kettle/”quick” sours or co-pitching with yeast. At 98F, it’s capable of achieving a pH of 3.3 within 18 hours. At 84F, it can reach a pH of 3.5 within 24 hours. With more time, a terminal ph of 3.1 may be reached.

P. pentosaceus can also be used for long-term sours. It is capable of growing and producing lactic acid in worts with IBUs as high as 30, though it is recommended for unhopped worts as IBUs over 10 may prevent significant souring.

This culture may produce antimicrobials called bacteriocins or pediocins. These can inhibit and kill similar species of bacteria like Lactobacillus and other Pediococcus species in mixed-culture fermentations. Read their Facebook post regarding bacteriocins for more info.

No signs of ropiness (exopolysaccharides) have occurred in testing.

Bootleg Biology is proud to announce The First Official Mad Fermentationist Culture

Fine tuned over two years, this blend morphed over time to become an elegant powerhouse of classic Saison spice, stone-fruit Brett, lactic tartness and a dry but well-rounded body. The final master blend consists of Saison yeast, wild Saccharomyces, rare Brettanomyces and an opportunistic Lactobacillus culture.

At temperatures as low as 68F (20C) The Mad Fermentationist Saison Blend exhibits a relatively clean primary fermentation profile and high attenuation. Traditional saison temperatures (around 80F/27C) bring out citrus and elevated phenols (pepper and clove). The Brett character shifts depending on wort composition, as maltier beers emphasize cherry and stone fruit qualities.

This blend integrates beautifully with fruity and tropical hops, with the unique Brett culture keeping hop aromatics crisp and bright for an extended time. For best results use a highly fermentable wort, dry hopping during the tail of active fermentation, and carbonating naturally.

OSLO is a modern take on traditional Norwegian farmhouse brewing cultures.

OSLO can comfortably produce beautifully clean, lager-like beers at temperatures as high as 98F (37C) without noticeable off flavors. At the high end of fermentation temperature, beers can finish attenuating in as little as three days! This culture’s versatility and neutral flavor profile allows you to effortlessly produce most beer styles.

Bootleg is the first yeast lab to release this unique Kveik-family culture sourced from a raw beer made by our good friends at Eik & Tid in Oslo, Norway.

More About Funk Weapon #2

Source: Family-owned brewery producing Gueuze in West Flanders, Belgium.

This rare, and commercially unavailable yeast isolate is perfect for 100% Brettanomyces fermentations, especially Brett IPAs. Amplifies citrus and tropical fruit-forward hop flavors and aromas into a punchy ripeness. With extended time under CO2 pressure, pineapple and tropical fruit aromas will be more pronounced. Great for maintaining the nuance of hops in beer with better keeping qualities than a Brewer’s Yeast fermentation.

Funk Weapon #2 is featured in Trinity’s Magical Brettanomyces Tour #4, and experimentations by Highland Park Brewery, Yazoo Embrace The Funk, Mantra Artisan Ales and others.

You can’t make every style of beer with one or two strains of brewer’s yeast, so why would you only use only one or two strains for your funky beers? This is the first release in the Dusty Bottoms Collection’s ongoing Funk Weapon Series of unique, rare Brettanomyces and Brett-like wild yeast cultures.
