Fermentis SafAle™ BW-20 is a specialty dry yeast designed for Belgian-style white beers (Witbier), offering a balanced profile with neutral fruity character and classic phenolic notes like clove and pepper. It is an excellent choice when you want expressive Belgian wheat beer character while still preserving mouthfeel and haze in the finished beer.

Fermentis SafAle™ BW-20 – 11.5 g Dry Yeast for Belgian-Style Whites

Classic Witbier Character with Clove, Pepper, and Lasting Mouthfeel

SafAle™ BW-20 is selected for brewing Belgian-style white beers and other wheat-forward ales where a phenolic yeast profile is desired. Fermentis describes this strain as producing neutral fruity flavors with specific clove and peppery notes, while not completely fermenting maltotriose, which helps retain body and mouthfeel. It also has low flocculation and forms a powdery haze when resuspended, making it a strong fit for hazy Belgian wheat styles.
