The granddaddy of American craft brewing hops, Cascade was bred in 1956 through a USDA program and first released in 1972. Its ancestry includes English Fuggle and Russian Serebrianka. Today it is the most widely-grown American aroma hop. The flavor and aroma are famously citrus-like (particularly ruby red grapefruit) with prominent floral tones. The classic finishing hop for pretty much any American craft style. Average Alpha: 4.5 - 7.0% AA. Substitute: CTZ, Centennial.
