WildBrew Sour Pitch™ is a high-performance, high-purity lactic acid bacteria specifically selected for its ability to produce a wide range of sour beer styles.

WildBrew Sour Pitch™ produces a clean and balanced citrus flavor profile typical of both traditional and modern sour beer styles. When inoculated at optimal temperature and the right conditions, it is a powerful, safe and easy way to handle bacteria for various beer souring techniques, such as a typical kettle souring process. Besides providing an outstanding performance, WildBrew Sour Pitch ™ is capable of delivering consistent results for brewers.

Styles brewed with this bacteria include, but are not limited to, Berliner Weisse, Gose, lambic, American Wild, and Sour IPA.

BREWING PROPERTIES

In Lallemand’s Standard Wort conditions, WildBrew Sour Pitch™ bacteria exhibits:

• Fast pH drop that can be completed within 1-2 days (typically within 24 to 36 hours).
• High lactic acid and low acetic production
• Aroma and flavor is citrus and tangy with a hint of fruit.

The optimal temperature range for WildBrew Sour Pitch™ when producing sour beer styles is between 30°C to 40°C (86°F to 104°F)

Souring rate, fermentation time and pH drop are dependent on inoculation density, bacteria handling, fermentation temperature and nutritional quality of the wort.
