Craving something cold and bold? Enjoy delicious, caramel flavored cold brew coffee at home. Just fill a glass with ice, then add equal parts water and Dunkinâ Caramel Flavored Cold Brew Concentrate. Or, for an even bolder taste, add more coffee concentrate. The result is smooth and pleasantly strong, not watery, because Dunkinâ coffee concentrates are specially roasted for cold coffee that stands up to ice. Drink your cold brew black, or customize it with your choice of sweetener and creamer....
