Mountain Dew Baja Blast, which features a Mexican-inspired tropical lime flavor, marks the first time an international beverage company and quick-service restaurant have collaborated to create a proprietary beverage specifically designed to complement the chain’s menu items. In a first-of-its-kind partnership with Pepsi, Taco Bell has announced the introduction of Mountain Dew Baja Blast, a soft drink available only at participating Taco Bell restaurants nationwide.
