Description
A lively West Country strain for brewers who want the yeast to be part of the flavor. It ferments fast and throws pronounced banana and tropical esters plus a sulfur note that conditions away, with a hint of spice from mild phenolics. Poor settling leaves the beer only moderately bright. Give it soft water and a traditional gravity.
