Mangrove Jack’s M54 Californian Lager yeast is a unique brewing strain developed for brewers who want lager-style results at ale fermentation temperatures. Each 10g packet treats up to 23 liters, or approximately 5 gallons, making it a practical choice for standard homebrew batch sizes.
This strain is especially well suited for California Common and other lager styles fermented at ambient ale temperatures. It is designed to ferment cleanly without the off flavors often associated with warmer lager fermentation, and it does not require extended lagering periods, helping simplify the brewing process.
M54 offers high attenuation and high flocculation, supporting a well-finished beer with dependable performance. For use, sprinkle directly onto up to 23 liters of wort. For best results, ferment at 18 to 20 degrees Celsius, or 64 to 68 degrees Fahrenheit. For storage, keep refrigerated.
