Calories in Starbucks Misto with lactose-free milk range from 44 in a Short to 127 in a Venti, notably lighter than the whole milk build.
A Grande comes to 97 calories with 3.6g of fat, well under the whole milk version’s 124 calories. This is a guaranteed dairy-safe pour, so you don’t have to worry about cross-contamination from a standard milk swap.
Since a Misto is mostly steamed milk, the milk choice here matters more than it would in a straight coffee, which is why lactose-sensitive drinkers often ask for this specifically rather than a plain brewed coffee.
