Empire Ale M15


Mangrove Jack's M15 Empire Ale is a top-fermenting ale yeast that will give the beer an exceptional depth. It will ferment with full rich dark fruit flavors if fermented at the correct temperatures. It has been carefully crafted to aid in the mouthfeel of a finished beer. 

You have to be careful with this strain to adjust hop bitterness to alleviate its tendency to produce an overly sweet beer. Higher alcohol beers will tend to be slightly too sweet and heavy due to the moderate attenuative capabilities of this strain although a lower mash temperature may help the fermentability and lower the final gravity. 

It is suitable for a wide range full bodied ale styles.

Flocculation: Medium-High

Attenuation: 70-75%

Optimal Temperature Range: 64-72F

Alcohol Tolerance: 8%

We recommend using M15 with these beer styles:

  • Scottish Heavy Ale
  • American Amber Ale
  • Sweet Stout
