The key differences between a galão coffee and a meia-de-leite lies in their milk-to-espresso ratios and serving styles. A galão has a higher proportion of milk to espresso, typically 3:1, and comes served in a tall glass. A meia de leite (in Portuguese: half milk) is similar to a café au lait. It uses a 1:1 ratio of milk to espresso and is served in a regular coffee cup.
