M15 Empire Ale is a top-fermenting dried ale yeast for full-bodied ales with real depth. It ferments with full, rich dark fruit flavours that suit malty and darker beers.

What it brings to your beer

  • Full, rich dark fruit flavours
  • Lower attenuation leaves body and malt sweetness
  • High flocculation for a clear beer
  • Suits Scottish heavy ales, American amber ales, sweet stouts and more

Specifications

  • Type: top-fermenting ale yeast
  • Attenuation: low-medium (70-75%)

How to use it

Sprinkle the contents directly onto up to 23 litres of wort and ferment at 18-22°C. Keep unused sachets in the fridge.

Pick M15 when you want a rounded, malt-led ale rather than a dry, hop-forward one - great with dark and amber beer kits or extract brews.
