Taco Bell is finally adding a second, permanent version of Baja Blast to its menus, with the passion fruit-flavored Mountain Dew Baja Midnight.

The passion fruit-infused Mountain Dew Baja Midnight arrives August 14, with a special free drink offer for rewards members the following day.

For the first time in 20 years, Taco Bell is making its first-ever permanent flavor expansion of the beloved Baja Blast. Baja Midnight is an “unexpected” purple twist on the iconic tropical lime beverage, blending the taste that fans already love with passion fruit flavor — a fruity spin on the citrusy classic.
