Clean, Crisp Lager Fermentation at Ale Temperatures
Mangrove Jack’s M54 Californian Lager Yeast is a unique lager strain engineered to ferment cleanly at ale temperatures (64–68°F / 18–20°C), eliminating the need for extended lagering periods or precise temperature control. This makes it an ideal choice for brewers aiming to produce crisp, refreshing lagers without the complexities associated with traditional lager fermentation.
With high attenuation (77–82%) and high flocculation, M54 ensures a thorough fermentation process, resulting in beers with excellent clarity and a dry finish. Its moderate alcohol tolerance of up to 9% ABV makes it suitable for a variety of lager styles, including California Common, Helles, and Pilsners. The yeast produces a clean lager aroma without the associated sulfur, allowing the malt and hop characters to shine through.
