Fermentation Notes
WLP840 produces a dry, clean lager with very slight apple character and minimal sulfur or diacetyl.
Ferment around 50 to 55°F for the classic profile. As with any lager yeast, larger batches, higher gravity beers, or colder pitching temperatures may benefit from a larger pitch.
PurePitch Next Generation
White Labs PurePitch Next Generation packages contain approximately 150 billion cells and provide a consistent pitch for more predictable fermentation.
Scan the barcode on the package and enter your batch information into the White Labs Pitch Rate Calculator to determine the recommended pitch rate for your beer.
The resealable cap also allows unused yeast to be refrigerated for a future batch.
Shipping Liquid Yeast
For best results, we recommend adding an ice pack when shipping liquid yeast.
During hot weather or longer transit times, we recommend choosing a dry yeast option when possible. Prolonged exposure to excessive heat can reduce liquid yeast viability.
