Hop Varieties Reference Guide

As has become the tradition around fresh hop season, I'm printing out a guide to the hop varieties you're likely to encounter in your travels.  There are a few things you should be aware of:

• Fresh hops behave differently than dried hops.  The flavors and aromas described here refer to the dried hop standard--what you get with a wet hop only your nose and mouth can tell you.
• Hop strains don't all taste the same.  Saaz grown in Yakima do not taste like Saaz grown in the Czech Republic.  Even strains grown in Yakima and the Willamette Valley taste different--never mind newer plantings that are springing up across the country.  The flavors and aromas listed below are general characteristics, not gospel.
• Some hops were developed by hop companies and are therefore proprietary strains.  This doesn't affect their quality at all, but it's an interesting feature in the hop-growing landscape.  As hop fever becomes the norm in the US, companies are racing to produce ever more exotic and tasty varieties (many of which find their way into test batches at places like Widmer and Russian River).  I've marked the proprietary strains in blue.
• If you read carefully, you'll notice that sometimes hops are described as being crossed with "unnamed" hops, which is just what it sounds like.  They have designations like USDA 65009-64034M (that's one of Crystal's parents).  It's different from "unknown" hop, which is more like it sounds--there is a lot of unknown parentage out there.
• In December, Stan Hieronymus's treatise For the Love of Hops will be out and no doubt demonstrate how crude my guides have been.  But since it's not December yet, enjoy!

Ezra has a full list of the beers/hops you'll find tomorrow in Hood River.

Aurora

• History. A high-alpha hop sometimes called the "super Styrian," though it is actually a cross between Northern Brewer and an unknown Slovenian hop.  Developed in the 1970s.
• Flavor/Aroma. Descriptions vary widely from spicy and earthy to tropical/pineapple. (alpha acid: 10-12% / beta acid: 4-5%. Total oils 1.1 - 1.8 ml.)

Amarillo

• History. Amarillo was discovered growing on Virgil Gamache Farms as a wild hop cross and is a proprietary strain owned by Yakima Chief.
• Flavor/Aroma. Described as a “super Cascade” with pronounced citrus (orange) and tropical fruit character (it can get seriously juicy). High in beta acids and a good aroma hop. (alpha acid: 8-11% / beta acid: 6-7%. Total oils 1.5-1.9 ml.)

Bravo

• History. A super-high alpha hop with principally Zeus and Nugget parentage released by SS Steiner in 2006.
• Flavor/Aroma. A pungent high-alpha hop that tends toward the earthy/spicy side of things (sometimes even minty)--similar to Chinook, but smoother. (alpha acid: 14-17% / beta acid: 3-5%. Total oils 1.6 - 2.4 ml.)

Brewer’s Gold

• History. A British bittering hop developed in 1919. Both Brewer's Gold and Bullion are seedlings found wild in Manitoba. It's an English/wild Canadian cross. Many modern high alpha hops were developed from Brewer's Gold.
• Flavor/Aroma. It has a resiny, spicy aroma/flavor with hints of black currant which some folks find objectionable. (alpha acid: 8-10% / beta acid: 3.5-4.5%. Total oils 1.6-1.9 ml.)

Bullion

• History. There are actually two lineages of Bullion.  The first was an English hop developed in 1919 where an unknown English hop was crossed with a wild hop gathered in Manitoba.  The second was a revival of the original in WA in the 1970s through heat treatment and meristem tip culture.
• Flavor/Aroma. A pungent and earthy/spicy hop with black currant notes.  (alpha acid: 7-13% / beta acid: 4-9%. Total oils 1.1 - 2.7 ml.) 

Cascade

• History. The first commercial hop from the USDA-ARS breeding program, it was bred in 1956 but not released for cultivation until 1972. It was obtained by crossing an English Fuggle with a male plant, which originated from the Russian variety Serebrianka with a Fuggle male plant.
• Flavor/Aroma. The most-used Northwest hop, with a lovely bright citrus and floral quality. (alpha acid: 4.5-7% / beta acid: 4.5-7%. Total oils 0.6-0.9 ml.)

Centennial

• History. Centennial is an aroma-type cultivar, bred in 1974 and released in 1990. The genetic composition is 3/4 Brewers Gold, 3/32 Fuggle, 1/16 East Kent Golding, 1/32 Bavarian and 1/16 unknown. Akin to a high-alpha Cascade.
• Flavor/Aroma. One of the classic "C" hops, along with Cascade, Chinook, and Columbus. Character is not as citrusy and fruity as Cascade and more "dank."  Some even use it for aroma as well as bittering. Clean Bitterness with floral notes. (alpha acid: 9.5-11.5% / beta acid: 3.5-4.5%. Total oils 1.5-2.5 ml.)

Citra

• History. Another of the recent proprietary strains, Citra is a relatively high-alpha dual-use hop that can be used either for bittering or aroma. Purported parentage includes Hallertauer, American Tettnanger, and East Kent Goldings.
• Flavor/Aroma. Lots of American citrus character, but tending toward mango and guava. (alpha acid: 11 - 13% / beta acid: 3.5 - 4.5%. Total oils 2.2-2.8 ml.)

Chinook

• History. Chinook hops were developed in the early 1970s in Washington state by the USDA; a cross of Petham Golding and Brewer's Gold.
• Flavor/Aroma. An herbal, smoky/earthy character that can overwhelm beers with a grating quality.  In late additions, is far cleaner and greener. (alpha acid: 12-14% / beta acid: 3-4%. Total oils 0.7-1.2 ml.) 

Columbia

• History. A sister to Willamette developed at OSU in the 1970s, it is, like Willamette, a Fuggle descendent.  It missed stardom when A-B chose Willamette instead.  Now enjoying a revival.
• Flavor/Aroma. Very much in the Willamette/Fuggle lineage--woody and earthy, with a lemon twist.  (alpha acid: 7-11% / beta acid: 3-5.5%. Total oils .5 - 1.6 ml.)

Columbus/Tomahawk/Zeus ("CTZ")

• History. The breeding nursery from which these varieties were bred contained 20-30 female plants from which seeds were gathered. Exact parentage is unknown.
• Flavor/Aroma. Hops have a very distinctive skunky/marijuana flavor and a sticky, resinous flavor. (alpha acid: 14.5 - 16.5% / beta acid: 4-5%. Total oils 2-3 ml.)

Crystal

• History. Crystal was released 1993, developed in Corvallis a decade earlier, a cross of Hallertauer Mittelfrüh, Cascade, and an unnamed hop.
• Flavor/Aroma. A spicy, sharp, clean flavor, citric in high concentration. It is not complex like Cascade but offers a clear note when used with other hops. (alpha acid: 4-6% / beta acid: 5-6.7%. Total oils 0.8-2.1 ml.)

First Gold

• History. A dwarf hop developed in England derived from a dwarf male and a Whitbread Golding variety.
