Hops play a crucial role in beer production primarily by adding bitterness, aroma, and flavor. The bitterness derived from hops balances the sweetness of the malt; without hops, beers would be overly sweet and unbalanced. The specific compounds in hops, such as alpha acids, are responsible for the bitterness that is measured in International Bitterness Units (IBUs). Additionally, hops contribute a wide range of aromatic and flavorful characteristics that can vary significantly depending on the hop variety used, thereby influencing the overall profile of the beer.

While hops do not significantly contribute to sweetness or color—that is primarily the domain of malt—they also do not enhance carbonation directly, as carbonation is typically a result of fermentation and the introduction of carbon dioxide. Furthermore, hops do not reduce fermentation time; rather, they can actually impact the fermentation process by providing antimicrobial properties that can affect yeast activity.
