Keurig () is a beverage brewing system for home and commercial use. The machines are manufactured by the American company Keurig Dr Pepper. The main Keurig products are: K-Cup pods, which are single-serve coffee containers; other beverage pods; and the proprietary machines that brew the beverages in these pods. Keurig beverage varieties include hot and cold coffees, teas, cocoas, dairy-based beverages, lemonades, cider, and fruit-based drinks. Through its own brands and its partnership licensed brands, Keurig has over 400 different varieties and over 60 brands of coffee and other beverages. In addition to K-Cup pods it includes Vue, K-Carafe, and K-Mug pods as well. The original single-serve brewer and coffee-pod manufacturing company, Keurig, Inc., was founded in Massachusetts in 1992. It launched its first brewers and K-Cup pods in 1998, targeting the office market. As the single-cup brewing system gained popularity, brewers for home use were added in 2004. In 2006 the publicly traded Vermont-based specialty-coffee company Green Mountain Coffee Roasters acquired Keurig, sparking rapid growth for both companies. In 2012 Keurig's main patent on its K-Cup pods expired, leading to new product launches, including brewer models that only accept pods from Keurig brands. From 2006 to 2014 Keurig, Inc. was a wholly owned subsidiary of Green Mountain Coffee Roasters. When Green Mountain Coffee Roasters changed its name to Keurig Green Mountain in March 2014, Keurig ceased to be a separate business unit and subsidiary, and instead became Keurig Green Mountain's main brand. In 2016 Keurig Green Mountain was acquired by an investor group led by private-equity firm JAB Holding Company for nearly $14 billion. In July 2018, Keurig Green Mountain merged with Dr Pepper Snapple Group in a deal worth $18.7 billion, creating Keurig Dr Pepper, a publicly traded conglomerate which is the third largest beverage company in North America.
