White Labs WLP550 Belgian Ale Yeast for Spicy, Expressive Belgian Fermentations
White Labs WLP550 Belgian Ale Yeast is a liquid Belgian strain for brewers who want a phenol-forward fermentation profile with peppery spice, layered aromatics, and enough versatility to cover a broad range of Belgian beer styles. It is especially useful in recipes where yeast character should stand out instead of disappearing behind malt or hops.
Based on White Labs strain guidance and the current live product data, WLP550 is known for clove, allspice, and peppercorn character, with medium to high alcohol tolerance and performance that suits blondes, browns, witbier-style beers, and other classic Belgian ales. It is also listed by White Labs as STA1 negative, which matters for brewers who want expressive Belgian character without a diastatic strain.

Liquid Yeast Storage and Shipping
We store liquid yeast in temperature-monitored refrigeration to help maintain yeast health before shipment. Once the package is in transit, carrier handling and weather are outside our control, so liquid yeast customers should choose shipping protection based on route, season, and expected transit time.
Expedited shipping, insulated mailers, and ice packs are recommended for liquid yeast, especially in warmer weather or on longer transit routes. Dry yeast is generally less risky to ship than liquid yeast.
