Now viewing: Brettanomyces and Bacteria
A blend of a traditional German Weizen yeast and Lactobacillus to create a subtle, tart, drinkable beer. Can take several months to develop tart character. Perfect for traditional Berliner Weisse.
This strain, used traditionally for wild yeast-like fermentations, produces a slightly tart beer with delicate characteristics of mango and pineapple. Can also be used to produce effervescence when bottle-conditioning.
(Formerly named Brettanomyces bruxellensis Trois)
Low intensity Brett character. Originally isolated from strong English stock beer, in the early 20th century. The Brett flavors produced are more subtle than WLP650 and WLP653. More aroma than flavor contribution. Fruity, pineapple like aroma. B. claussenii is closely related to B. anomalus.
The vrai (true, in French) Brettanomyces bruxellensis Trois. The infamous strain used for all-Brettanomyces fermentations, has a robust, complex sour character with aromas of pear. Best used as a primary fermentation strain.
Medium intensity Brett character. Classic strain used in secondary fermentation for Belgian style beers and lambics. One Trappist brewery uses this strain in secondary fermentation and bottling to produce their characteristic flavor.
High intensity Brett character. Defines the "Brett character": Horsey, smoky and spicy flavors. As the name suggests, this strain is found most often in Lambic style beers, which are spontaneously fermented beers. Also found in Flanders and sour brown style beers.
Pediococcus damnosus is a cocci bacteria known for its souring capabilities by producing lactic acid. Perfect to add to any sour program. High diacetyl producer and slow growing.
Blended culture used to produce the classic beer styles of the West Flanders region of Belgium . A proprietary blend of Saccharomyces yeasts, Brettanomyces, Lactobacillus, and Pediococcus, this culture creates a more complex, dark stone fruit characteristic than WLP 655 Belgian Sour Mix
Inspired by local American brewers crafting semi-traditional Belgian-style ales. This blend creates a complex flavor profile with a moderate level of sourness. It consists of a traditional farmhouse yeast strain and Brettanomyces. Great yeast for farmhouse ales, Saisons, and other Belgian-inspired beers
Malolactic Fermentation is the conversion of malic acid to lactic acid by bacteria from the lactic acid bacteria family. Lactic acid is less acidic than malic acid, which in turn decreases acidity and helps to soften and/or round out some of the flavors in wine. These liquid cultures are available in vials to inoculate 6 gallons or 1 liter sizes to inoculate 60 gallons.
Please note: We recommend caution with using WLP675 with wine kits, which contain potassium sorbate and effect the viability of malolactic bacteria. Under FAQ questions below, you will find instructions for using WLP675 with wine kits.
General instructions are under FAQs below.
