Description
A heritage strain from a well-known South Yorkshire brewery, aimed squarely at sessionable cask bitter. The ferment is clean and malt-forward, leaving gentle biscuit and soft apple with a slightly nutty finish that flatters moderate bitterness. It wants high-mineral wort and a sensible gravity.
