A high alpha acid bittering hop with mild flavor and low aromatic characteristics.
Hop Growers of America InformationMagnum is a high alpha variety that was developed at the Hop Research Center in Huell, Germany. It is widely grown in the Hallertau region of Germany, and is also grown in the U.S. Magnum is a good bittering hop for Ales and Lagers.

OTHER INFORMATION: Very large cones that tend to break up and shatter during picking. Some tendency to form angel cones (small leaflets in the cone which drives up leaf and stem data. The hop is a diploid, 2n= 20. This hop is the major high-alpha hop in Germany and is rapidly becoming the most widely grown hop in that country.
