SAN DIEGO, Calif. — Dunkin’ is celebrating National Cold Brew Day Thursday by pouring free drinks for customers.

For one day only on April 20, rewards members can snag a free cold brew with any purchase through the Dunkin’ mobile app. Not a member? There’s still time to sign up to score this icy deal.

The on-the-go beverage and donut brand says it steeps 100% Arabica beans in cold water for 12 hours to slowly extract the coffee flavor. Dunkin’ described their cold brew as “an ultra-smooth, full bodied cold coffee with a sweeter, rich chocolatey taste.”
