Nick Carr on November 5, 2016 0 Comments History of Magnum Hops Just a year or two ago, Hallertauer Magnum was the main bittering hop grown in Germany. According to the 2015 Northern Hemisphere Hop Report (PDF) the Herkules variety has taken over the top spot, but Magnum still enjoys the second place spot and continues to be popular around the world. Its consistent popularity stems from a relatively high alpha acid content which includes (PDF) high amounts of humulone, but comparatively low cohumulone. Click Here to Buy Magnum Hops This combination is thought to create a less harsh, more pleasant bitterness, with little to none of the “grassiness” present in many other high alpha varieties. Combine this property with a rather non-descript aroma due to the overall combination of oils and you have one of the finest “clean” bittering hops around. Magnum was bred at the Hops Research Institute of Hüll, Germany; a city right smack dab in the middle of the renowned Hallertau hop growing region. Its pedigree is made up of a combination of Galena (a U.S. super-alpha variety) and a male German variety with only the number designation 75/5/3. The Magnum breeding program was started in 1980 and culminated in its release to commercial markets in 1993. Today, Magnum hops are grown in a number of countries beside Germany, including Poland, America, and France. In the U.S., it is limited to minimal plantings in the Pacific Northwest. Those grown in Germany are often called Hallertauer Magnum, indicating the region of origin. A slight change in character, due to environmental factors or terrior, might be expected depending on where the hop is grown. But this difference will be minimal and almost impossible to distinguish.

Generally, these qualities are characterized as faint or weak, but in line with some noble hops. It may have hints of spice and citrus with some inclination toward mild flowery and/or fruity flavors. Bitterness is balanced with medium intensity and a hoppy tang. Use: The Magnum hop variety is most often used for its neutral bittering properties, which allows it to combine well with most other hop varieties. It is not often used for later hop additions because it offers an aroma similar to Saaz and other noble hops, but at a much reduced level. This resemblance to noble hops, its clean bitterness, and higher alpha acid content make it a cheaper alternative to bittering with the more expensive “true” nobles. To this end, you can save your nobles for the delicate work of flavor and aroma, and use Magnum for the early additions.
