Have you ever watched “A New Hope” when Luke is staying with aunt Beru and uncle Owen Lars and thought to yourself: “I wonder what that blue milk he’s drinking actually is?”
The original Blue Milk you see Luke drinking in “A New Hope,” is actually called Bantha Milk, because it was produced by the giant beasts in the outer rim territories.
The Blue milk has Pineapple, Lime, Dragon Fruit, and Watermelon. The Green milk, on the other hand, has Passion Fruit, Grapefruit, Mandarin Orange, and Orange Blossom flavors.
