Mangrove Jack's M44 - US West Coast Yeast 10g

Mangrove Jack's M44 US West Coast Yeast

Mangrove Jack's M44 is a clean American-style ale yeast designed for hop-forward beers where you want the malt and hops to stay firmly in the foreground.

Its high attenuation gives a crisp, relatively dry finish, making it particularly useful for American pale ales, IPAs and stronger hop-led beers.

Yeast Details

• Yeast Type: American-style ale yeast
• Pack Size: 10g
• Fermentation Temperature: 18–23°C
• Attenuation: 77–85%
• Flocculation: High

How to Use

Sprinkle the contents directly onto up to 23 litres of cooled wort and ferment within the recommended temperature range. For wort above approximately 1.050, Mangrove Jack's recommends increasing the pitching rate.

Substitutes

SafAle US-05 is the closest active alternative for a clean, neutral American ale fermentation. LalBrew Nottingham is another clean option, but it flocculates more strongly and can give a firmer, drier finish.

Brewer's Tip

M44 is best when you want the hops to do the talking. Keep fermentation steady and avoid pushing it warm if a neutral profile is the priority.
