What it brings to your beer

  • Soft, delicate and balanced lager character
  • Dry, clean finish that lets noble hops show
  • High flocculation for a bright beer after lagering
  • Suits German and Bohemian pilsners, all lager styles and German bocks

Specifications

  • Type: bottom-fermenting lager yeast
  • Attenuation: high (72-76%)

How to use it

Cool the wort to lager temperature, sprinkle the sachet directly onto up to 23 litres and hold it at 10-15°C. A thermometer helps you keep it in range. Store sachets in the fridge.

Made for brewers who can ferment cool and want a classic, crisp continental lager. If you can only ferment at room temperature, look at M54 Californian Lager instead.
