Description
A heritage Yorkshire strain giving moderate esters and a nutty edge, with a light sulfur note that fades in conditioning. It is lightly POF positive, so a whisper of spice can show up in the finish. Krausen is enormous, so plan for headspace, rousing or antifoam. It needs high-mineral wort to finish and does not like strong worts.
