McDonald’s is significantly expanding its beverage offerings this summer, introducing a new line of drinks inspired by its recently closed CosMc’s spin-off concept at hundreds of locations across the United States.

This strategic move is part of a comprehensive market test involving over 500 U.S. restaurants, allowing the fast-food giant to gauge customer reception and operational efficiency before a potential wider rollout.

The inspiration for these new beverages directly stems from CosMc’s, the standalone drive-thru concept launched in late 2023, which predominantly specialized in innovative and customized drink creations before its closure earlier this year.

Among the highly anticipated additions are the Creamy Vanilla Cold Brew, the vibrant Strawberry Watermelon Refresher, the unique Sprite Lunar Splash, the exotic Popping Tropic Refresher, and the delightful Toasted Vanilla Frappé, catering to diverse palates.

McDonald’s chief customer experience and marketing officer, Alyssa Buetikofer, emphasized the growing momentum in the beverage sector, particularly among Gen Z consumers who increasingly seek flavorful, cold drink options for refreshment and treats.

This initiative underscores McDonald’s commitment to adapting to evolving consumer tastes and capitalizing on new consumption occasions, such as afternoon snack breaks, by offering a wider array of appealing drink choices.

The company views this extensive test as a crucial learning phase to identify which specific beverages resonate most with the American market and how to integrate them seamlessly into existing operations for smart and rapid scaling in the future.

CosMc’s initially debuted with its first location in the Chicago suburbs, followed by a limited expansion into Texas, before McDonald’s made the decision to incorporate successful elements of its menu into the core brand.
