Magnum hops are a German hop variety that is widely used in brewing for its clean bitterness and versatile aroma characteristics.

Here are some key features of Magnum hops:

1. Flavor Profile: Magnum hops are primarily known for their clean and neutral bittering properties. They have a mild, resinous, and slightly herbal flavor. While they are often chosen for bittering, their flavor is not overpowering, allowing other hop varieties to shine in the aroma and flavor departments.
2. Aroma: Magnum hops are not typically used for their aroma, as their primary role is in providing bitterness. However, they can impart a mild and pleasant hop aroma when used in larger quantities late in the brewing process.
3. Usage: Magnum hops are commonly used for bittering additions in brewing. They are added early in the boil to maximize their contribution to the beer's bitterness. Due to their clean and neutral profile, Magnum hops are often utilized as a base bittering hop in a wide range of beer styles.
4. Alpha Acids: Magnum hops have a high alpha acids content, typically ranging from 12% to 16% or higher. This high alpha acids content makes them effective for providing a substantial amount of bitterness to a beer.
5. Beer Styles: Magnum hops are suitable for a variety of beer styles, including but not limited to Pale Ales, India Pale Ales (IPAs), lagers, stouts, and more. Their clean bitterness makes them a popular choice for brewers who want to control bitterness without introducing strong hop flavor.
6. Origin: Magnum hops were bred at the Hüll Hop Research Institute in Germany and released in 1980. They are a cross between Galena and a German male hop.

Magnum hops are often favored by brewers for their reliable bittering properties and versatility. While not as aromatic as some other hop varieties, Magnum's clean bitterness makes it a valuable addition to a wide range of beer recipes, allowing other hop varieties to shine in the aroma and flavor departments.
