"Currently, more than half of the SUBWAY® restaurants in the United States and Canada have adopted a Keurig® system," according to a news release. The single-serve hot beverage system was introduced as an option for restaurant franchisees last year.
The sandwich franchise is the world's largest restaurant chain, with more than 42,000 locations in 106 countries. Its store count exceeded that of McDonald's in 2011,according to the Wall Street Journal.
Keurig hot beverage brewers will replace traditional coffee makers in the brand's North American locations. Subway said in the Keurig release that the single-serve system will make it easier for restaurants to offer hot beverages any time of day.
Coca-Cola invested heavily in Keurig Green Mountain starting in February 2014, as part of a strategic partnership to develop and sell a cold-beverage version of the coffee roaster's "K-Cup" brewing system.
