Comet Hops

Comet Hop Profile

Despite its USDA release in 1974 and decline in the 1980s, Comet splashed back onto the scene in the 2010s as brewers rediscovered its well-rounded flavor profile. Comet is zesty with grapefruit and tangerine, rounded out by unique lemongrass and herbal elements — often described as “wild American.” Comet’s unique aroma produces one-of-a-kind beers, proving that some classics are worth rediscovering.
