Description
A north-east English strain for traditional bitters and session beers, giving light pear and floral notes with very little sulfur. Fermentation is unhurried, often a week or two, and it needs soft, low-mineral wort to perform. Poor settling leaves a soft haze that suits ordinary bitters, best bitters and milds. Keep the gravity modest.
