White Labs WLP540 Abbey IV Ale Yeast: Elevate Your Brews with Balanced Belgian Character
Craft Authentic Abbey-Style Ales with Medium Fruit Complexity
White Labs WLP540 Abbey IV Ale Yeast is an authentic Trappist-style strain, ideal for brewing traditional Belgian ales such as Dubbels, Tripels, and Belgian Strong Ales. This yeast produces a balanced fruit aroma and flavor profile, offering a medium ester character that sits between the high fruitiness of WLP500 and the subtle notes of WLP530.

Our Commitment to Yeast Health
At SoCal Brewing Supply, we take yeast storage and viability very seriously. We ensure yeast is always stored under optimal conditions, with 24-hour monitoring of refrigerator temperatures to prevent spikes that could negatively impact yeast health.
For liquid yeast orders, we recommend shipping with an ice pack and insulated envelope to ensure your yeast arrives in top condition. It's normal for ice packs to melt during transit; their purpose is to protect the yeast from extreme temperatures caused by external weather conditions.
