American craft beer refers to beer produced by small, independent breweries that prioritize quality, flavor, and traditional brewing methods. These breweries often experiment with unique ingredients and styles, resulting in a diverse range of flavors and aromas. The craft beer movement began in the late 20th century and has grown significantly, with thousands of breweries operating across the United States. Craft breweries typically focus on local distribution and community engagement, often creating seasonal or limited-edition brews. The Brewers Association, a non-profit organization, defines craft breweries based on their production volume and independence, ensuring that they maintain their commitment to quality and innovation.
