White Labs French Saison Ale Yeast (WLP590) is one of White Lab's most popular saison strains. It produces flavors and aromas of pear, apple, and cracked pepper. This strain is a high attenuator that will produce a very dry and drinkable finishing beer.

WLP590 French Saison Ale Yeast is POF+ meaning that it will contribute phenolic characteristics to finished products.

This yeast strain is perfect for Farmhouse Ales, but works well in Belgian Dark Strong Ales, Belgian Table Biers, Belgian Wits, and Saisons. 

It also is a fantastic choice for French Ciders, New England Ciders, Sweet Ciders, and Traditional Perrys.

Attenuation: 78-85%

Flocculation: Medium

Alcohol Tolerance: Medium (5-10%)

Optimum Fermentation Temperature:  69 - 75F

**This strain has been genetically typed in our lab using polymerase chain reaction (PCR). Through this genetic testing, we have determined WLP590 French Saison Ale Yeast 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 internal and external fermentation data.**
