Notes

Recommended for Scottish heavy, American amber, sweet stout, English brown.

Character: Malt-forward English character leaving body and residual sweetness.

A malt-forward English strain with a low 70 to 75% attenuation that leaves body and sweetness, so it suits Scottish heavies, ambers and sweet stouts where the malt should lead. It is the wrong strain for a dry beer; use a higher-attenuating ale yeast there.
