Milk is a natural liquid that comes from any mammal. It is commonly drank at breakfast. It is also a flavour included in Bertie Bott's Every Flavour Beans. In 1981, early in the morning Petunia Dursley found the infant Harry Potter on her doorstep while setting out empty milk bottles. It was served at breakfast at Hogwarts School of Witchcraft and Wizardry in 1996.

Milk may be delivered by milkmen.
