People have been brewing coffee for more than 500 years, but if you go into a kitchen today to look at how it’s made, you’ll probably see a process that bears little resemblance to the methods used just a generation ago. In homes and businesses alike, consumers are shifting to the cup-at-a-time pod-style brewing pioneered by Keurig in the 1990s as an alternative to the messy communal office coffeepot. The company began moving into the home market in 2004, and sales took off. K-Cups now come in more than 200 flavors and sell for about 50 cents apiece. That’s 10 times the cost per cup of coffee brewed by traditional methods, but consumers are willing to pay for the speed and convenience: In 2012 U.S. sales of Keurig coffeemakers and pods exceeded $3.8 billion, and the coffeemakers had a dollar market share of more than 40%.
