Belgian Strong Ale Yeast | White Labs WLP545 Yeast

White Labs WLP545 Belgian Strong Ale Yeast for Rich, High-Gravity Belgian Ales White Labs WLP545 Belgian Strong Ale Yeast is a liquid Belgian strain for brewers chasing layered dark fruit character, reliable performance in bigger beers, and the kind of expressive fermentation profile that suits Belgian strong ales, quadrupels, and other higher-gravity abbey-inspired recipes. It is a strong fit when you want yeast character to contribute real depth without turning hot or rough. White Labs describes WLP545 as an Ardennes-origin strain that produces moderate ester and phenolic character, often noted as dried sage and black cracked pepper, with the kind of high attenuation that helps stronger Belgian beers finish dry. Current manufacturer references point to roughly 78% to 85% attenuation, medium flocculation, a recommended fermentation range of 66 to 72°F, and STA1 positive behavior, making it a better fit for brewers who want expressive Belgian strength and a dry finish in bigger beers.
