Hop

In brewing, a "hop" refers to the flower of the hop plant, which is used to add bitterness, flavor, and aroma to beer. When boiled with the wort, hops release compounds called alpha acids, providing a bitter balance to the sweetness of the malt. They also contribute a range of aromatic qualities, such as citrus, pine, or floral notes, enhancing the beer's complexity. Hops act as a natural preservative, extending the beer’s shelf life. Overall, hops are essential ingredients that influence the beer’s taste, aroma, and stability.
