Calories in Starbucks Cortado with semi-skimmed milk come to 49 total, identical to the low-fat version — “semi-skimmed” is simply the British English name for that same milk.
Whether you’re ordering this in the UK or the US, a Cortado’s small, single-size format means the milk naming barely matters for the calorie count either way. It’s still 49 calories of equal-parts espresso and steamed milk, no matter what you call the milk.
For the American labeling, both low-fat and lactose-free milk pages carry this same number.
