Notes
Recommended for Irish red ale, dry stout, Irish stout, porter.
Character: Slight fruity ester with a subtle dry, roasted character.
The Guinness-associated Irish strain, giving a slight fruitiness and a subtle dry, almost roasted character that suits stouts and Irish reds. It flocculates well and leaves a clean, dry finish that lets roasted malt lead. It is the go-to when a stout should taste dry and Irish rather than sweet.
