In early 2016, doughnut-and-coffee mainstay Krispy Kreme began testing a new prototype, featuring a revamped layout, a barista and free Wi-Fi, to boost coffee sales. The chain also recently debuted new limited-time coffees with premium Arabica beans sourced from Sumatra, Colombia, Guatemala and Brazil. Two years ago, Krispy Kreme launched three ready-to-drink iced coffees in mocha, vanilla and caramel flavors for retail sale.
