Challenger hop

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.

American

Ahtanum brand YCR 1 cv

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.

Amarillo brand VGXP01 cv

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.

Apollo

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)

Beta acids: 5.5–8% (ASBC Spectrophotometric method)

Alpha/beta ratio: 3.0–3.5

Cohumulone (% of alpha-acids): 24–28%

Colupulone (%of beta-acids): 52%

Total oils (mls/100 g): 1.5–2.5

Humulene (% of total oils): 20–35%

Azacca

Azacca has predominately citrus and tropical fruit notes, consisting of mango, papaya, orange, grapefruit, lemon, piney, spicy, pineapple, grassy, tropical fruit, citrus aromas. Named after the Haitian god of agriculture, Azacca. Alpha: 14–16%; Beta: 4.0–5.5%

Calypso

Dual-purpose high alpha hop with aromas of pear, apple and earthy tea.

Cascade

Very successful and well-established American aroma hop developed by USDA-ARS's breeding program in 1956 from Fuggle and Serebrianka (a Russian variety), but not released for cultivation until 1972. It has a flowery and spicy, citrus-like quality with a slight grapefruit characteristic. One of the "Three Cs" along with Centennial and Columbus. Substitutes: Centennial and Columbus (but they have a higher Alpha Acid content).

Centennial

American aroma-type variety bred in 1974 and released in September 1990 by S.T. Kenny and C.E. Zimmermann, the breeders of this variety. Similar to Cascade and Chinook. The genetic composition is 3/4 Brewers Gold, 3/32 Fuggle, 1/6 Golding, 1/32 Bavarian and 1/16 Unknown. One of the "Three Cs" along with Cascade and Columbus. Centennial is often referred to as a 'Super Cascade', since it has a strong citrus aroma.

Chinook

This green bine cultivar (W-421-38) was released in May 1985 in Washington State and Idaho from a cross between a Petham Golding and a USDA-selected male (63012M). Slightly spicy and very piney. Its alpha acid content ranges from 12% to 14%. Substitutes for bittering: Eroica, Galena, Nugget. Substitutes for aroma and flavor: Southern Cross, Sticklebract.

Citra brand HBC 394 cv

Citra Brand is a registered trademark used with HBC 394 cv special aroma hop variety developed by the Hop Breeding Company (a joint venture between John I. Haas, Inc. and Select Botanicals Group, LLC) and funded by Sierra Nevada, Deschutes, and Widmer Brothers breweries. It was released in 2007. Citra Brand hops have fairly high alpha acids and total oil contents with a low percentage of cohumulone content. Citra Brand hops imparts citrus (grapefruit) and tropical fruit characters to beer.

Cluster

Originated from mass selection of the Cluster hop, which is an old American cultivar. It is suggested that they arose from hybridization of varieties, imported by Dutch and English settlers and indigenous male hops. There is an early ripening and a late ripening Cluster cultivar. Also known as Golden Cluster. They can give a blackcurrant aroma/flavor. Substitutes: Brewer's Gold.

Columbus

A high yielding, high alpha acid American bittering hop. Also known by the trade name Tomahawk. One of the "Three Cs" along with Cascade and Centennial. Like the others it is citrusy and slightly woody. Columbus has a very high amount of total oils, and can impart a 'resiny' quality to a beer. Substitutes for bittering: Nugget, Chinook. Substitutes for aroma and flavor: Cascade, Centennial.

Comet

A rare US grown hop, originally bred for its bittering characteristics. Said to have character similar to wild American hops that are "objectionable to some brewers".

Crystal

An American triploid variety developed in 1993 from Hallertau, Cascade, Brewer's Gold and Early Green. It is spicier than Hallertau (cinnamon, black pepper, and nutmeg). Substitutes: any Hallertau variety, Mount Hood, Liberty.

El Dorado

Developed by CLS Farms and formally released in the fall of 2010. High alpha with tropical fruit flavors.

Ekuanot

Developed by the Hop Breeding Company and released in 2014. A high oil content hop known for strong aroma including fruitiness, eucalyptus, clove, and tobacco. Formerly known as Equinox. 14.5 - 15.5% Alpha acids.

Eroica

This cultivar with its pale green bine was bred in 1968 with its sister Galena from Brewers Gold with an open pollination. It was released in 1979 in Idaho, one of the three hop cultivation areas on America's West Coast It is strongly "catty" flavored bittering hop with an alpha acid content ranging from 10–13% and used often in wheat beers. Substitutes: Galena, Nugget, Olympic.

Galena

A cultivar developed in 1968 from Brewer's Gold by open pollination in Idaho. An open pollination means that the male hop is unknown.
The alpha acid content is relatively high—11.5 to 13.5%—but its co-humulone content and its beta acid range are also high.

Glacier

Low-cohumulone American Fuggle descendant. Substitutes: Eroica, Nugget, Olympic.

Greensburg

American Hop grown in southern Idaho.

Horizon

American high alpha cross made in Oregon in 1970. Horizon and Nugget share a common parent (#65009).

American 1983 cross between Hallertauer Mittlefrüh (USDA 21397) and downy mildew resistant male (USDA 64035M). Spicy (cinnamon), resiny, and slightly sweet. It is an early ripening variety and similar in technical data and aroma to Hallertau Mittelfrueh. Recommended for German/American lagers. Alpha acids are relatively low at 2-6%. Substitutes: Mount Hood, Hallertau, Crystal.

Mount Hood

Soft American variety developed from Hallertau. Frequently used in styles that require only a subtle hop aroma (German/American lagers). Named for Mount Hood in Oregon. Substitutes: Liberty, Hallertau, Crystal.

Mount Rainier

Originally cultivated in Oregon. Mount Rainier has a complex parentage, including Hallertau, Galena, Fuggle and other hops, and exhibits some noble hop characteristics, but is higher in alpha acid. The aroma is reminiscent of licorice with a hint of citrus.
