Calories in Starbucks Cortado with lactose-free milk match the standard order exactly at 49 calories, served in the same single small size as every other Cortado.
Since a Cortado is such a small, concentrated pour to begin with, there’s little room for milk choice to swing the calorie count much either way. Naming lactose-free here mainly guarantees the barista reaches for that carton specifically, which matters if you’re managing lactose intolerance.
Both low-fat and semi-skimmed milk versions land on this same number.
