Hello Kateia. Thanks for stopping by the Disney Parks Moms Panel with your question.
I, too, am getting so excited for
Star Wars: Galaxy's Edge to open at
Disney's Hollywood Studios later this summer. It's going to be amazing. I did some digging for you and couldn't find the exact ingredient list that you are looking for at this time. On Disneyland's website the menu does talk about the Blue and Green Milk being plant-based blends of coconut and rice milks served frozen, which sounds delicious, However, right now on the Walt Disney World website for the
Milk Stand, the menu has not been posted. While normally I would think it would be safe to assume the ingredients would be similar, I wouldn't risk it with a food allergy. If you are in desperate need to find out before your trip, I suggest getting in contact with the
Special Diets team at Walt Disney World. If you are dealing with multiple food allergies this team is amazing. Just be sure to email them at least 14 days prior to your trip so they'll be able to help you out to the most of their potential. If you don't reach out to them before your trip, you can always stop by the Milk Stand and request more information about all of the ingredients in these specialty beverages.
Fun fact! Luke Skywalker can be seen enjoying blue milk in Star Wars: Episode IV – A New Hope, and green milk in Star Wars: Episode VIII – The Last Jedi.
I hope this helps point you in the right direction. If you have any other questions, please feel free to come back and ask.
