List of hop varieties

This is a list of varieties of hop (Humulus lupulus).

As there are male and female plants, the flowers (cones) of the female plant are fertilized by the pollen of the male flowers with the result that the female flowers form seeds. These seeds are eaten by birds and hence spread over vast distances. Hops, specifically their female plants, have been grown as a commercial crop for the brewing industry for many centuries in many countries. The first documented mention of a hop garden is in the will of Pepyn III. The first breeding of different hop varieties took place at Wye College in Kent, England by E. S. Salmon in 1919 when he bred the varieties "Brewer's Gold" and "Bullion". As of 2012, there are around 80 varieties in commercial use around the world, and considerably more in development/trials.

Ahtanum brand YCR 1 cv is an aroma-type cultivar bred by Yakima Chief Ranches. It is used for its aromatic properties and moderate bittering. It has unique aromas that include citrus (grapefruit), earthy, and floral. The variety is named after the location where Charles Carpenter established the first hop farm in the Yakima Valley in 1869. Typical alpha acids range from 5%–7%, and beta acids range from 5%–6%. Typical total oils (Mls. per 100 grams dried hops) 0.8 – 1.2.

Popular American mid-range alpha acid variety with a unique and distinct aroma discovered growing "wild" (spontaneously) in one of their hop yards and developed by Virgil Gamache Farms in the late 20th century. Also known as VGXP01, and named in honor of Virgil Gamache the patriarch of the family.

Characterized by its exceptionally high percentage of alpha acids (15.0 – 19.0%), excellent storage stability of alpha acids, low CoH (CoHumulone) value for an alpha variety, and resistance to hop powdery mildew strains found in Washington. The new variety was cultivated as a result of a cross in 2000 at Golden Gate Roza Hop Ranches in Prosser, Washington, and has been asexually reproduced there.

Alpha acids: 15 – 19% (ASBC Spectrophotometric method)
