Hop Varieties: From Noble Hops to Citra and Beyond
Hops are the spice rack of brewing. A brewer choosing between Saaz and Simcoe is making the same kind of fundamental flavor decision as a cook choosing between caraway and jalapeño — the categories overlap (both are hops, both add bitterness and aroma) but the results in the glass are worlds apart. Understanding the major hop families and their characteristics is one of the highest-leverage investments a beer drinker or aspiring brewer can make.
Noble Hops: The European Originals
The noble hops are a group of four traditional European varieties associated with the great lager-producing regions: Saaz (Bohemia), Hallertauer Mittelfrüh (Bavaria), Tettnanger (Baden-Württemberg), and Spalt (Franconia). The term "noble" has no technical definition but captures shared characteristics: low alpha acid content (3–6%), high cohumulone/isohumulone ratios that produce soft rather than harsh bitterness, and complex aromatic oils dominated by farnesene and myrcene in proportions that yield floral, herbal, earthy, and lightly spicy notes without the citrus or tropical fruit associated with American varieties.
Saaz is the defining hop of Czech pilsner. Pilsner Urquell uses Saaz almost exclusively, and the hop's spicy, chamomile-like character is what gives Czech pilsner its distinctive aromatic identity. The Saaz growing region around Žatec (German: Saaz) has been protected as a geographic indication, and locally grown Saaz commands significant premium over Saaz-type hops grown elsewhere. Bavarian breweries likewise emphasize the terroir argument for Hallertauer Mittelfrüh: the specific combination of soil, climate, and elevation in the Hallertau region produces a hop with a gentler floral character than Hallertauer varieties grown in Oregon or New Zealand.
American C-Hops
The American craft beer revolution was built largely on the "C-hops" — a group of American varieties beginning with the letter C that were developed partly as higher-yielding, disease-resistant alternatives to European nobles and partly as distinct flavor profiles for a market that was not bound by tradition. The group includes Cascade, Centennial, Chinook, Columbus (also known as Tomahawk or Zeus, hence CTZ), and Cluster.
Cascade, released by the USDA in 1972, is the variety most directly associated with the birth of American craft beer. Sierra Nevada Pale Ale, introduced in 1981, was the first nationally distributed beer to prominently feature Cascade's grapefruit and floral character, and it set the template for American pale ales for a generation. Stone Brewing's Arrogant Bastard Ale used Chinook alongside Cascade to push the pine-resin intensity that defined West Coast IPA. Bear Republic's Racer 5 and Lagunitas IPA both rely heavily on Centennial, which shares Cascade's grapefruit character but with more floral complexity and slightly higher alpha acid content.
The New Generation: Citra, Mosaic, Simcoe
The early 2000s saw private breeding programs — most significantly those run by John I. Haas and Hopsteiner in Washington State and by Yakima Chief Hops — begin producing varieties with dramatically different aromatic profiles from the established C-hops. Citra (released 2008) has become arguably the most commercially important hop variety in the world since Cascade. Its essential oil profile is dominated by linalool (floral), geraniol (citrus, rose), and myrcene in a combination that produces an intensely tropical and citrusy aroma — passion fruit, lime, lychee — that has become the default language of American IPA.
Mosaic (released 2012) adds blueberry, earthiness, and tropical complexity alongside the citrus that makes it a natural companion to Citra. The combination of Citra and Mosaic has become so ubiquitous in hazy IPAs that some drinkers and critics have debated whether it constitutes a genuine style marker or simply a marketing reflex. Simcoe (released 2000) carries pine, catty/dank, and passion fruit character with high alpha acids, making it a workhorse for bittering and a contributor of resinous complexity in West Coast IPAs. Russian River's Pliny the Elder uses Simcoe alongside Centennial and Columbus/Tomahawk to build its benchmark double IPA.
New Zealand Hops
New Zealand's hop industry developed largely independent of European and American programs, producing varieties with unusual flavor profiles traced partly to New Zealand's distinct growing conditions and partly to the use of wild New Zealand hops as breeding parents. Nelson Sauvin, named for the Sauvignon Blanc-like white wine character its essential oils produce, is the variety that put New Zealand on the global hop map. Beers made with Nelson Sauvin — particularly pale ales and IPAs from New Zealand breweries like Yeastie Boys and Garage Project — have a white wine, gooseberry, and tropical character that is immediately identifiable and unlike any American or European variety.
Motueka (derived partly from Saaz) produces lemon and tropical lime character. Waimea (high alpha, lemon and tangerine). Wakatu (formerly Hallertau Aroma) provides a floral, citrus-forward character useful for late additions. Riwaka, not widely exported, produces intensely grapefruity character in New Zealand beers and is intensely sought by importers.
Australian Hops
Australian breeding programs, centered in Tasmania, have produced Galaxy and Vic Secret as the most internationally significant varieties. Galaxy (released 2009 for commercial use, though developed through the 1990s) is extraordinary in the intensity and diversity of its tropical fruit character: passionfruit, mango, peach, and citrus in concentrations that dominate a beer even at modest dry-hop rates. It has become a key component of Australian craft beers from breweries like Stone & Wood and Balter, and is increasingly used by American craft breweries either alone or alongside Citra.
Vic Secret (released 2013) provides pineapple, passionfruit, and a pine-herb character that complements Galaxy in dual-dry-hop protocols. Ella (formerly Stella) has distinctive anise and floral character. Topaz provides strong tropical and citrus notes at high oil content.
Sabro and the Latest Generation
Sabro (released 2018 by the Hop Breeding Company) represents the latest generation of American breeding, deriving partly from a wild neomexicanus hop parent — a native American species distinct from the European-derived varieties that form most commercial breeding stock. Sabro's aroma profile is unusual: coconut, cedar, tropical fruit, and a creamy richness that makes it unlike any other commercial hop. It has been used in limited-release beers by Odell Brewing, Dogfish Head, and many others as a novelty that can also serve as a complex supporting hop in hazies.
The Hop Breeding Company (joint venture of John I. Haas and Yakima Chief) and programs at Michigan State, Oregon State, and private breeders continue to release new varieties at an accelerating pace, driven by craft brewers' appetite for novel aromatics and the commercial incentive of exclusive licensing. Idaho 7, Strata, Cashmere, and HBC 630 have all generated significant interest since 2017. The variety landscape today is radically different from what it was even ten years ago.
