Which of the following flavors is commonly found in American hops?

Resin is a flavor commonly associated with American hops, primarily due to the specific compounds present in the hop varieties cultivated in the United States. These hops, such as Cascade, Citra, and Centennial, are known for their high levels of aromatic oils and resins, which contribute to distinct flavors and aromas in beer. The resin character often provides a piney or sticky quality that enhances the overall bitterness and complexity of American-style beers, particularly in IPAs.

In contrast, other flavors like clove, earthy, and peppery are typically more representative of European hops or specific styles influenced by traditional brewing techniques. For instance, clove notes can be particularly evident in certain Belgian or German styles, while earthy flavors might be found in older hop varieties or malts used in some English ales. Peppery notes are often associated with specific yeast strains or other factors rather than being characteristic of American hop profiles. Therefore, the strong resin profile is a defining feature of American hops and is widely recognized in the craft beer industry.
