The new caramel iced coffees join the company’s complete lineup of iced coffee flavors, including Blueberry, Caramel, Cinnamon, Coconut, French Vanilla, Hazelnut, Mocha, Raspberry and Toasted Almond.

The ice coffee involves a double brewing process that uses twice the amount of coffee when making the beverage to achieve consistent flavor and freshness, eliminating bitterness, claims the company.

The new flavors will be available at participating Dunkin’ Donuts restaurants for a limited time in the US.

Dunkin’ Brands chief global marketing and innovation officer John Costello said: "With the addition of our limited time only caramel iced coffee flavors, guests have more options than ever to customize their favorite warm-weather beverage for that perfect pick-me-up."
