Description
Famously reticent: pitched cool it contributes almost no ester character at all, which lets the malt do the talking. Attenuation stops short of dry, so a higher-than-usual final gravity is expected rather than a fault. Nudge the temperature up for a little more fruit. A sound house strain when you want the yeast to stay out of the way.
