Hoppy beer is a type of beer that features a strong flavor and aroma from hops, which are the flowers of the hop plant, Humulus lupulus. Hops contribute bitterness, floral, and citrus notes, balancing the sweetness of the malt. Common styles of hoppy beer include India Pale Ales (IPAs) and Pale Ales, which are popular among craft beer enthusiasts. The level of hoppiness in beer is often measured in International Bitterness Units (IBUs). Higher IBU values indicate a more pronounced hop flavor. Hoppy beers can vary widely in taste, with some showcasing tropical fruit notes while others may have earthy or piney characteristics.
