Commonly brewed from cereal grains (barley, wheat, rice) with the addition of hops for flavor, beer is one of the oldest, and most popular, alcoholic beverages in the world. You’ll find a nearly unlimited variety of U.S. styles, variations, and regional takes on beer. From ubiquitous lagers, pilsners, ales, and stouts to craft brews that often aspire to stick out with unusual or unexpected — but delicious just the same — ingredients.
