What one-word characteristic describes the American hop varieties?

The characteristic that best describes American hop varieties is "citrus." Many American hop varieties are known for their strong citrus aroma and flavor profiles, which often include notes of grapefruit, orange, lemon, and lime. This citrus quality is particularly prominent in popular hop varieties such as Cascade, Citra, and Amarillo, making it a defining feature of American hops in the brewing industry.

This distinct citrus character is often sought after in various beer styles, especially in American Pale Ales and IPAs, where brewers aim to create bright, refreshing beers that showcase these vibrant hop qualities. The emphasis on citrus in American hops has influenced modern craft beer trends and brewing practices, differentiating them from European hop varieties, which may feature more earthy, floral, or herbal notes.
