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.
What White Labs WLP545 Contributes to Beer
- High-gravity capability: Well suited to stronger Belgian beers where a more delicate strain can struggle
- Expressive Belgian profile: Moderate esters and phenolic spice help shape complex abbey and dark strong ales
- High attenuation: Helps stronger Belgian beers finish drier and more drinkable instead of heavy or sticky
- Abbey-style versatility: A good option when you want expressive Belgian character across several strong ale formats

Why Brewers Choose WLP545
WLP545 is especially useful when a recipe needs strong attenuation, real Belgian ester character, and the ability to handle elevated alcohol without flattening out. It gives brewers a practical path to richer Belgian strong ales that still finish with balance.
For brewers building bigger abbey-style beers with layered fruit complexity and a polished finish, WLP545 remains a very workable liquid culture.
Liquid Yeast Storage and Shipping
We store liquid yeast in temperature-monitored refrigeration to help maintain yeast health before shipment. After it leaves our hands, carrier handling and outside temperatures are outside our control, so liquid yeast buyers should choose shipping protection based on season, route, and expected transit time.
Expedited shipping, insulated mailers, and ice packs are worth considering for liquid yeast, especially during warm weather or on longer routes. Dry yeast is generally less risky to ship than liquid yeast.
