Brewer notes
American Lager Yeast is a liquid lager culture from White Labs (WLP840). Fermentation character can show apple, clean, and fruity notes. Useful for lagers. Reference guidance: attenuation guidance 75–80%, fermentation range about 10–13°C (50–55°F), alcohol tolerance around 8%. Treat temperature, attenuation and alcohol tolerance as strain guidance; wort composition, pitch health and fermentation management still affect the result.
