In the U.S., we drink $200 billion worth of the hops-brewed libation annually. What many Americans might not know is that most domestic beer, 90 percent in fact, is dominated by just two companies: Anheuser-Busch InBev and MillerCoors.
Innovators, however, are challenging that dominance in the form of craft beer breweries. Small "mom and pop"-style breweries — or regional breweries — now account for about 6 percent of domestic beer sales. That may seem like a small number, but it's been growing every year since the early 1990s, while big brewers' share is declining.
