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 add bitterness and aroma. Hops are essential for balancing the sweetness of malt, contributing to the overall flavor profile of the beverage. This perennial plant can grow up to 20 feet tall and thrives in temperate climates. Besides its role in brewing, Humulus lupulus has been used in traditional medicine for its calming properties, often found in herbal teas and supplements to promote relaxation and sleep.
