If you drink beer—any beer—you’ve likely heard of the craft beer revolution, and you likely fall into one of two camps: IPA warrior or lager loyalist. The great thing about a beer-related revolution is that there is no wrong side. Whatever your preference, cheers to you.

The burgeoning brewery business is indeed a revolution by many counts. According to the Brewers Association, the number of breweries in the United States grew 390% from 2010 to 2020—all while beer consumption, on average, was declining. As of 2019, more than 90% of California’s population lived within 10 miles of a craft brewery.

Like all revolutions, this, too, began as a desire for change—as an overthrow of the old and the monopolistic. In 2010, Anheuser-Busch InBev and Molson Coors (formerly MillerCoors), two of the largest beer companies in the world, comprised roughly 77% of total beer sales in the U.S. In 2020, that share was 60%, with smaller brewers claiming a larger share toward the end of the decade.
