Mangrove Jack's M42 - New World Strong Ale Yeast 10g

Mangrove Jack's M42 New World Strong Ale Yeast

Mangrove Jack's M42 is a clean, high-performance ale yeast that keeps fermentation character restrained so malt and hops remain at the front of the beer.

Its strong attenuation and very high flocculation make it useful for pale ales, IPAs, porters and high-gravity ales where a reliable, clean finish is required.

Substitutes

LalBrew Nottingham is a strong alternative for clean, highly attenuative ales with excellent settling. SafAle US-05 is another clean choice, particularly for hop-forward American styles.

Brewer's Tip

M42 is useful when you want reliable attenuation and quick settling without adding a large ester signature. It is a particularly good fit for malt- or hop-led recipes.
