NEW YORK — The battle over the world’s coffee drinkers is getting hotter.

Keurig, the maker of single-cup coffee machines that sit on millions of kitchen counters, agreed to sell itself Monday for almost $14 billion. The buyer, JAB Holding, is a private company with a growing java business.

Fans of Keurig may not see much of a difference in their caffeine fix. JAB Holding said Keurig will operate independently and remain in its headquarters in Waterbury, Vt.

The Keurig deal will help boost JAB Holding’s already robust coffee empire. The Luxembourg-based company has a controlling stake in Jacobs Douwe Egberts, the company behind Gevalia, Tassimo and many other brands. It also has stakes in Peet’s Coffee & Tea and Caribou Coffee, two companies that already have deals in place to make coffee pods for Keurig machines.

Buying Keurig will get JAB Holding closer to coffee market leader Nestle, said Stifel analyst Mark Astrachan. He also said JAB Holding may try to sell more Keurig brewing machines internationally.

Outside of coffee, JAB Holding has stakes in beauty products maker Coty and high-end shoe seller Jimmy Choo.

The deal comes as Keurig has reported slowing sales of its machines and K-cups, the pods that are used in Keurig’s machines.
