White Labs East Coast Ale Yeast WLP008 can be used to reproduce many American versions of classic beer styles but has been gaining popularity for its use in East Coast IPAs. It is cleaner and crisper than other haze producing strains. It possesses the similar neutral character of WLP001 California Ale Yeast® with slightly higher ester production. This strain’s attenuation leaves some mouthfeel and residual sweetness which balances hop bitterness. It’s a great all-around strain for balanced, accessible beer styles such as blondes, pale ales and amber ales.

White Labs Dry English Ale Yeast WLP007 is known for its high attenuation, achieving 80% even with 10% ABV beers. The high attenuation eliminates residual sweetness, making the yeast well-suited for high gravity ales and clean, well-attenuated beer styles. This strain has become a go-to house strain for American breweries due to its clean profile and high attenuation. It’s an ideal strain for American and English hoppy beers as well as malty ambers, porters and brown ales. This strain can be a substitute for WLP001 California Ale Yeast®.

White Labs Irish Ale Yeast WLP004 is from one of the oldest stout-producing breweries in the world. It’s great for many beer styles but really shines in malty British styles such as stouts, porters and brown ales. Medium attenuation helps with a dry finish that promotes roasty notes. Esters help round out the overall flavor making a soft drinkable stout.

White Labs California V Ale Yeast WLP051 is a big ester producer, showcasing notes of cherry and apple which compliment pale ales, blonde and brown ales. Typically leaves some residual, lager-like sulfur compounds in finished beer. Recent sequencing studies show that this strain belongs to Saccharomyces pastorianus species, the same hybrid species as most lager strains. However, this strain has been used to make ales for decades and was previously categorized as belonging to Saccharomyces cerevisiae.
