Whataburger is giving away iced coffee for the summer solstice

Thursday marks the summer solstice, and Whataburger is helping customers cool down with a free 16-ounce iced coffee.

Driving the news: It's the longest day of the year, and officially the first day of summer, and the Texas fast food chain will make their iced coffee available from 6am-6pm at their locations across 15 states.

• Customers also can snag their free drink at the drive-thru and online through the Whataburger website or app.

Zoom in: You can customize your coffee with one of the chain's three new flavors — vanilla, caramel or mocha.

Between the lines: Whataburger has ramped up its coffee game this year, rolling out new hot and iced brews last month.

Dig deeper: You can watch our Axios Texas social host Greg Castillo try the new coffee drinks for the first time on Instagram. While you're there, make sure to follow the Axios Texas and Axios San Antonio accounts.
