Coffee milk at Dunkin' is a drink made with whole milk combined with Dunkin's proprietary coffee extract, which is similar to the traditional Rhode Island coffee milk made from sweet coffee syrup like Autocrat or Eclipse
. It is described as a milky, sweet coffee-flavored beverage, somewhat like chocolate milk but with coffee syrup instead of chocolate syrup
. Dunkin' introduced this coffee milk as part of their Dunkalatte, a seasonal fall menu item that blends the coffee milk with espresso, resulting in a creamy, sweet drink that tastes like a "melted milkshake" with coffee flavor
. Some customers also use coffee milk as a substitute for regular milk in cold brews, drip coffees, or iced coffees to add a thick, sweet coffee flavor
. However, coffee milk at Dunkin' cannot be substituted with lactose-free or alternative milk options, unlike most other milk choices on their menu
. The drink is quite sweet due to the coffee syrup content, so it is recommended to adjust additional flavorings or shots accordingly if used in other drinks
. In summary, Dunkin's coffee milk is a sweet, creamy milk infused with a special coffee syrup or extract, inspired by Rhode Island's state beverage, and is featured mainly in their Dunkalatte drink during the fall season
