Blue milk

Blue milk, also known as Bantha milk, was a rich blue-colored milk produced by female banthas. Sentients drank it, and also used it in bantha butter, blue bantha buttermilk biscuits, blue-milk cheese, blue milk custard, ice cream, and yogurt. It was notably available on Outer Rim planets such as Batuu, Lah'mu, Lothal, and Tatooine. Cid's Parlor on Ord Mantell served a similar beverage that was alcoholic called Dark Blue Milk.

During a lightsaber training session, the young Ezra Bridger had to protect himself as the astromech droid Chopper kept lobbing cartons of blue milk at him. Luke Skywalker drank blue milk while he discussed the new droids, R2-D2 and C-3PO, with his aunt and uncle.

Two establishments in Black Spire Outpost on Batuu, served blue milk or blue milk-based concoctions; Milk Stand sold blue milk and an alcoholic Blue Milk Cooler, while Oga's Cantina served the non-alcoholic Blue Bantha.

Blue milk first appeared in Star Wars: Episode IV A New Hope, the first installment in the original trilogy of Star Wars. Initially, one scene was to have featured Beru Lars, played by Shelagh Fraser, pouring blue milk into a jug in her kitchen. That footage, however, was left on the cutting room floor.

Mark Hamill stated the blue milk was "life-long milk" with "additives – they put blue food coloring in it – and it was really ghastly. Oily and sweet and euch! Triggered your gag reflex. But I said, 'Look – if they gave me blue milk, you bet I'm going to drink it on camera, because what other chance am I going to get?' So there's an indication that I'm an underrated actor – I gulped it and acted like I liked it without vomiting."

The anthology novel From a Certain Point of View, celebrating the 40th anniversary of A New Hope, was first teased on social media on April 6, 2017, using the hashtag #OperationBlueMilk.

The real-world Milk Stand found at Star Wars: Galaxy's Edge serves "blue milk," which is actually a frozen plant-based blend of coconut and rice milks that the menu describes as having "alluring fruity characteristics." The Disney's Hollywood Studios location additionally serves an alcoholic Blue Milk Cooler. The real-world Oga's Cantina at both parks serves Blue Bantha, a non-alcoholic cocktail with a cookie.

The 2020 non-canon video game expansion The Sims 4 Star Wars: Journey to Batuu includes blue milk as a drink sold to the player's Sims at the Milk Stand vendor in the Black Spire Outpost neighborhood. In the home neighborhood, it can be purchased as a quick meal from refrigerators.
