Description
The standard choice for New England IPA: it holds a stable haze, throws strong hop-leaning fruit esters and leaves a soft, full body because it does not touch maltotriose. Expect low attenuation, especially in strong worts. To dry it out, mash cooler, overpitch and finish warm. Also a good British cask strain.
