McDonald’s plans to test new coffee drinks, refreshers, and flavored sodas at over 500 locations, targeting Gen Z customers who love fun, colorful beverages. The lineup includes options like Creamy Vanilla Cold Brew and Toasted Vanilla Frappe. McDonald’s hopes to learn customer preferences and compete with fast-growing beverage chains.

McDonald’s is testing the new drinks in Wisconsin, Colorado, and surrounding areas to gather feedback and make the expanded drink lineup work for its restaurants and franchisees. This move comes after the closure of CosMc’s stand-alone locations, with McDonald’s incorporating CosMc’s beverage influences into its own offerings.

The expanded drink lineup aims to boost McDonald’s sales, which have been lackluster in recent quarters. The chain reported a 3.6% drop in U.S. same-store sales in the first three months of the year. Competitors like Taco Bell, Wendy’s, and KFC are also exploring new drink options to appeal to customers and drive sales.

McDonald’s hopes that the new drinks will attract more customers to its restaurants, as consumers are spending less on traditional menu items like fries and burgers. The chain’s second-quarter results are expected to be reported on August 6. Expanding the beverage lineup is seen as a strategy to stay competitive in the fast-food industry.
