In 1873, there were more than 4,000 breweries in the United States. That number dropped to zero with the arrival of Prohibition in 1920, and although a handful survived the Volstead Act, there were fewer than 300 in the entire country for most of the 20th century. Today, the industry has bounced back -- to more than 5,300 breweries. Still, if they were people, the oldest breweries in most states would hardly be old enough to buy a beer. Here are 20 that likely wouldn't have to show ID.
