A hop of any other color…
By Mark Tichenor & Bruce Lish
The hop flower is a key ingredient in beer. Its flavor and aroma balance the sweetness of the grain, and hop bitterness gives many beer styles their allure and distinction. Like any plant, hops have their differences, and when making beer, brewers select from that palette of hop varieties to achieve the appropriate characteristics of taste and smell. Let’s talk about these differences, because we have a column to turn in.
Hops don’t grow everywhere, and availability played a large part in the development of regional styles. For example, hops are among the awesome variety of plants that don’t grow well in Scotland, so Scotch ale evolved as dark, malty and very sweet, with no hop bitterness to balance things out.
Conversely, in Bohemia (the border country between the Czech Republic that somehow got associated with filthy hippies), hops thrive. It was in this region that cultivation of the little buggers began sometime in the 8th century.
In fact, four of these hop species, Tettnang, Hallertau, Spalt and Saaz, are so prized by lager brewers that they’re now termed ‘noble hops.’ Limited regional cultivation areas make them a pricey ingredient, but they’re indispensable because of their low bitterness, dominant aromas and ability to mesh with the clean flavor of bottom-fermented lagers. Bavarian Helles and Hefeweizen wouldn’t turn out the same without Tettnang, Spalt and Hallertau., and Saaz gives Czech pilsners like Urquell and Czechvar their characteristic snappy finish.
In the UK, at least the parts that aren’t Scotland, local hop varieties took on a different set of characteristics. The classic hops for English ale, Goldings and Fuggles, putout hearty, sweetish flavors that may not be evident in a beer’s nose. English hops are subtle, much like English people, at least prior to the heavy consumption of fluids containing English hops. And what brewer from the UK could resist using a hop with a name like ‘Fuggles?’ It sounds like a children’s TV show.
Some English hop varieties, such as Bullion and Brewers Gold, have a higher concentration of alpha acids, the chemical responsible for making bitterness and preservative qualities. It turns out Americans like lots of bitter in their beer, and frankly the English hops don’t have enough of it. In the Pacific Northwest, they fixed that.
When you order an American double IPA and get a glass of liquid gold that smells like a DEA raid, and the bitterness of which puckers your face into a grotesque inverse rictus grin, you’re tasting Pacific Northwest hops. The rainy climate suits staple high-acid varieties like Cascade, Amarillo and Chinook.
Pacific northwest varieties are the hops of choice for big, aromatic, beers. Their domineering presence balances, and often completely overwhelms, the heavy malt and alcohol flavors of high-gravity styles like barley wine, American IPA, and the aforementioned double IPA.
American hops are changing beer worldwide. Breweries with deep local beer traditions now intrigue drinkers by marrying the more aromatic and bitter US varieties with traditional styles.
In Belgium, a country where hops grow poorly and traditional beers have very little hop presence, there’s a new beer style: Belgian IPA. The Urthel and Chouffe breweries now brew this intriguing hybrid that meshes the earthy spiciness of a Belgian dubbel with the floral aromas and tonsil-punching bitterness of an American IPA. The combination works so well that American breweries make their own variations (we recommend Flying Dog Raging Bitch Belgian IPA as the standout).
Over in stolid, conservative Bavaria, the centuries-old Brauerei Schneider collaborates with the Brooklyn Brewery to make Hopfen-Weisse, melding the classicest of classic German Hefeweizens with the complex aromas and flavors of American hops. It’s not always a happy blend, but it makes for a change of pace beer that refreshes and intrigues.
Brewers use dozens of hop varieties, and new types are created all the time. Developments in hop cultivation, combined with an increasing worldwide brewing evolution, are what keep the beer scene fresh, interesting, and ever changing. As well as giving lazy columnists something to write about.
