If not used within 18 minutes, Dunkin’ Donuts coffee is discarded and a new carafe is freshly brewed. Dunkin’ Donuts uses 100 percent Arabica coffee beans, imported from South and Central America, and which has its own coffee specifications, recognized by the industry as a superior grade of coffee.
