American Farmhouse Blend WLP670

White Labs American Farmhouse Blend (WLP670) is inspired by local American brewers crafting semi-traditional Belgian-Style Ales. It will create a complex flavor profile that has a moderate level of sourness. This blend consists of a traditional farmhouse yeast strain and Brettanomyces.

 It is a fantastic choice for Farmhouse Ales, Saisons, and other Belgian-Inspired Beers.

Attenuation: 75-82%

Flocculation: Medium

Alcohol Tolerance: Medium (5-10%(

Optimum Fermentation Temperature:  68 - 72F

**This strain has been genetically typed in our lab using polymerase chain reaction (PCR). Through this genetic testing, we have determined WLP670 American Farmhouse Blend to contain the STA1 gene (glucoamylase), a potential indicator of Saccharomyces cerevisiae var. diastaticus. Brewers yeast are natural hybrids, which make it possible for certain strains to display elements of the STA1 gene. These strains have the ability to utilize some dextrins (unfermentable sugars), resulting in higher levels of attenuation than what is considered typical.  

At White Labs, we do everything possible to detect for undesired organisms within our process and cultures. The strains we carry with known Saccharomyces cerevisiae var. diastaticus genetics have been researched and validated to perform without excessive over-attenuating, which is possible through our nearly 25 years of experience paired with our internal and external fermentation data.**
