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

IN-STOCK YEAST: We maintain stock of high-selling liquid yeasts in the shop, to make it easy for anyone who needs liquid yeast in a hurry. These will always be sold within the best before date. If a strain is out of stock, then it won't show up as an option for you to purchase. If you want the freshest liquid yeast, or if we are out of stock, consider using the pre-order option. Pre-ordered yeasts are ordered directly from the manufacturer on your behalf and we do not use in-stock yeast to fulfil pre-orders.

PREORDER DEADLINE: Every 2 months we place a liquid yeast order with Wyeast. All pre-orders placed will be part of our next order from the supplier, subject to the supplier having your pre-ordered strain in stock.

We place our orders on or after the 20th of the month. The deadline to ensure your pre-order is included is midnight the day before.

All pre-orders will be available for pickup or shipping after we receive the yeast which is usually around the first week of the month.

*Note: we will ship your order when your yeast arrives, so if you wish to place an order for other items and want to receive them sooner, please place a separate order.
