Over the past several years, McDonald’s Corp.’s sales growth has outpaced many of its major quick-service peers in the United States. While company executives credit a balanced approach of marketing core products, its Dollar Menu and premium items like Angus Third Pounders, they also regularly have cited the McCafé beverage line as a major sales driver.

Since its nationwide rollout in May 2009, McCafé has helped McDonald’s grow its coffee sales from 2 percent of U.S. sales to more than 6 percent, while combining with the Breakfast Dollar Menu to strengthen a morning daypart in which the chain is considered a pioneer and leader.
