M24 Versa Lager is Mangrove Jacks' flexible lager yeast — designed for brewers who want authentic lager character but work with a wider temperature range than traditional lager strains allow. Where M84 and M76 require strict 8–14°C fermentation, M24 can produce good lager character from 10°C up to 20°C, making it accessible to brewers with modest cooling capability.

Best suited to: Pilsner, Munich Helles, Märzen, Cream Ale, Blonde Ale, American Lager — any style where clean, crisp lager character is the goal.

Fermentation parameters:

• Temperature: 10–20°C (wider range than traditional lager yeasts)
• Attenuation: High
• Flocculation: High
• Pitching rate: 1–2 sachets per 23L; pitch 2 sachets below 14°C

Flavour contribution: Clean, crisp, and neutral. More forgiving than M84 or M76 if temperature fluctuates slightly during fermentation. The lager character is authentic at 10–14°C and remains acceptable up to 20°C — unlike traditional lager yeasts which produce off-flavours above 15°C.

Choose M24 over M84/M76 when your temperature control reaches 14–18°C but not the 8–12°C required for traditional lager fermentation. Choose M54 over M24 when you must ferment at ale temperatures with no cooling at all.

Diacetyl rest: After primary fermentation, raise temperature to 18°C for 48 hours before cold crashing. Important for clean lager character.

Storage: Keep refrigerated. Once opened, reseal and use within 7 days.
