Humulus lupulus, commonly known as hops, is a climbing plant in the Cannabaceae family. It is primarily used in the brewing of beer, where its flowers, or cones, add bitterness, flavor, and aroma. Hops also have preservative qualities, helping to extend the shelf life of beer. This perennial plant can grow up to 30 feet in a single season and thrives in temperate climates. Hops are dioecious, meaning there are separate male and female plants, but only the female flowers are used in brewing. Additionally, hops have been studied for their potential health benefits, including anti-inflammatory and calming effects.
