Mangrove Jack's M15 - Empire Ale Yeast 10g

Mangrove Jack's M15 Empire Ale Yeast

Mangrove Jack's M15 is a characterful English-style ale yeast that produces rich dark-fruit esters and a full, rounded mouthfeel.

Its lower attenuation and high flocculation make it particularly useful for malt-led beers where body and yeast character are more important than a very dry finish.

Yeast Details

• Yeast Type: English-style ale yeast
• Pack Size: 10g
• Fermentation Temperature: 18–22°C
• Attenuation: 70–75%

How to Use

Sprinkle the contents directly onto up to 23 litres of cooled wort and ferment within the recommended temperature range.

Substitutes

LalBrew Windsor is a useful alternative when you want a fruity, full-bodied ale with lower attenuation. SafAle S-04 is faster and generally finishes drier while retaining a recognisably British ale profile.

Brewer's Tip

M15 is a strong choice for recipes that should retain body and malt richness. If the target beer needs to finish crisp and dry, use a more attenuative strain.
