Cascade is used widely in American beers, and is the predominant hop in most West Coast ales. Cascade imparts a pleasant citrusy (usually grapefruit), zesty flavor and floral/citrus aroma. It was released in 1972 and is one of the most recognisable US hops. Developed via open pollination of a Fuggle seedling, which was a cross between Fuggle and the Russian hop Serebrianker. Used in US pale ale, India pale ale, porter and barleywine.
