Blue Milk Cooler, an alcoholic drink, was offered for sale at the Milk Stand situated in Batuu's Black Spire Outpost. This beverage was a variation of the non-alcoholic frozen blue milk drink that was already available at the Milk Stand; the original drink consisted of milk sourced from local female banthas, but the cooler version had rum added.
Both Blue Milk and Green Milk beverages debuted at the Milk Stand in Star Wars: Galaxy's Edge within both Disneyland and Disney's Hollywood Studios on the day the parks opened. However, only the Hollywood Studios location featured alcoholic "cooler" versions of these drinks. The Blue Milk Cooler's description on the menu states: "A plant-based mixture of Coconut and Rice Milk, exhibiting captivating fruity notes, and infused with Bacardi Rum."
