Magnum Hops

BitteringAlpha 11.0 - 16.0%Germany

Magnum is the undisputed champion of European bittering, a variety that revolutionized German hop farming by introducing high-alpha efficiency to the Hallertau. Originally bred at the Hop Research Institute in Hüll and released in 1980, it is a cross between the American Galena and German male 75/5/3. Despite its American lineage, Magnum has become the definitive "Noble" high-alpha hop, offering the clean structural integrity required for precise German brewing standards. Brewers rely on its high resin concentration to achieve high IBUs with minimal plant matter, which significantly reduces "grassy" off-flavors and trub loss, making it a professional-grade anchor that respects the delicate balance of malt and yeast.

The aromatic profile of Magnum is one of intentional subtlety and refined spice. Because it was bred to be a neutral bittering agent, it avoids the aggressive tropical or citrus notes found in modern "flavor" hops. Instead, it provides a very mild, "continental" bouquet of dried black pepper, pine needles, and a faint, floral earthiness. On the palate, its impact is felt rather than tasted—providing a "firm" but velvety bitterness that clears the palate quickly without leaving a heavy or resinous coating. Thanks to its remarkably low cohumulone levels, the bittering sensation is perceived as rounded and soft, making it the industry standard for styles where a clean finish is paramount.
