Calypso Hops

Dual: Aroma and BitteringAlpha 11.0 - 14.0%United States

Calypso stands out as an exceptionally distinct, high-impact dual-purpose powerhouse within the modern American craft brewing landscape. Originally uncovered in 2005 at an experimental test plot in Prosser, Washington, and officially patented by Hopsteiner in 2014, this proprietary diploid cultivar was meticulously created by crossing the elite breeding female 98005 with a robust Hopsteiner male line derived from Nugget and USDA 19058m germplasm. Calypso shatters conventional brewing boundaries by pairing a massive, clean high-alpha bittering potential with an extraordinarily complex, aroma-focused essential oil matrix. For growers and brewers alike, it represents a premier commercial asset, offering robust vine vigor, early seasonal ripening, and remarkably heavy, shatter-proof cone yields that explode with aromatic depth when utilized in late-kettle, whirlpool, and intensive dry-hopping additions.

The sensory blueprint of Calypso delivers a wonderfully vibrant and delightfully unconventional spectrum of bright white orchard fruit, crisp citrus, and lush tropical sweetness. The bouquet opens with an unmistakable, headlining perfume of snappy green apples, sun-ripened Bosc pears, and dripping white peaches. This lively orchard fruit canopy is dynamically elevated by a bright mid-palate burst of sweet honeydew melon, zesty lime peel, and a soft whisper of delicate cherry blossoms. Deep in the background, a highly refined, sophisticated layer of earthy green tea and cracked black pepper emerges, creating a complex, grounding baseline. Its exceptionally concentrated oil volume ensures that these bright fruit characteristics remain highly stable and completely free of harsh, lingering astringency or sulfur-forward notes during fermentation and dry-hop saturation.

Substitution Tip

If you can't find Calypso, the best alternatives are Belma®, El Dorado®, Galena, Huell Melon, or Rakau.
