Mangrove Jack's M54 - Californian Lager Yeast 10g

Mangrove Jack's M54 Californian Lager Yeast

Mangrove Jack's M54 is a hybrid-style lager yeast selected to produce a clean lager-like profile at ale-friendly temperatures.

It is particularly useful for California Common and for brewers who want lager character without a traditional cold lager fermentation or an extended lagering schedule.

Yeast Details

• Yeast Type: Hybrid lager yeast
• Pack Size: 10g
• Fermentation Temperature: 18–20°C
• Attenuation: 77–82%
• Flocculation: High
• Character: Clean, lager-like and low in warm-fermentation off flavours
• Good For: California Common and warm-fermented lager styles

How to Use

Sprinkle the contents directly onto up to 23 litres of cooled wort and ferment at 18–20°C. Mangrove Jack's classifies M54 as a hybrid strain, so use lager-style pitching guidance for stronger wort.

Substitutes

Mangrove Jack's M24 Versa Lager is the closest same-range alternative when you want a clean lager fermentation across a wider temperature range. SafLager W-34/70 is a better choice for a conventional cool-fermented German lager profile.

Brewer's Tip

M54 is useful when refrigeration is limited, but it is not simply an ale yeast sold as a lager yeast. Keep it within its narrow recommended range for the cleanest result.
