Dunkin’ coffee is also one to be talked about. Dunkin’ coffee is freshly ground, freshly brewed and freshly served. If not used within 18 minutes, Dunkin’ coffee is discarded and a new carafe is freshly brewed. Dunkin’ 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.
