SAN DIEGO, Calif. — Dunkin’ is celebrating National Frosty Brew Day on Thursday by offering customers free drinks.
For one day only, April 20th, loyalty program members can receive a free cool beer with every purchase through Dunkin’ Mobile App. Not a member? You still have time to sign up and get this icy deal.
The on-the-go beverage and donut brand says it steeps 100% Arabica beans in cool water for 12 hours to slowly extract the coffee’s flavor. Dunkin’ described its cool brew as an “ultra-smooth, full-bodied cool brew with a sweeter, richer chocolate flavor.”
Adding cool foam, a burst of flavor, or a swirl of flavor? Prefer a specific type of milk? Dunkin’ has a solution for you. This exclusive offer allows for personalization.
Want to try something novel? Dunkin’s menu features the Caramel Chocolate Frosty Brew, which is described as “tasty notes of caramel and prosperous milk chocolate.” This special drink is also topped with a chocolate cool brew marshmallow and a cocoa caramel sprinkle.

There is also a Frosty Brew with a sweet cool foam that is described as having a “sweet, vanilla flavor.” It is also topped with a creamy foam.
