Whataburger is marking the longest day of the year by offering free iced coffee to customers on Thursday, June 20.
In celebration of the summer solstice and the official start of summer, the Texas-based fast food chain will provide complimentary iced coffee from 6 a.m. to 6 p.m. at all of its locations across 15 states.
“Whataburger fans can caffeinate their way through the day with the most sunlight,” the company announced in a news release.
Customers can claim their free iced coffee in-store, at the drive-thru, online at Whataburger.com, or through the Whataburger smartphone app. However, the promotion is not available on third-party delivery apps.
Additionally, new users of the Whataburger app can enjoy a free Whataburger and access other exclusive offers by creating a new account.
Whataburger’s iced coffee is crafted from a premium blend of 100% Arabica beans sourced from Colombia, Honduras, and Nicaragua. The beverage boasts a bold aroma of dark-roasted coffee with a vibrant finish, featuring nutty, smoky, and toasted flavor notes, according to the company.
Customers can enjoy the iced coffee black or personalize it with one of three new flavors: vanilla, caramel, or mocha.
