Calories in Starbucks Matcha Green Tea Latte with lactose-free milk range from 82 in a Short to 217 in a Venti, a lighter build than the whole milk version.
A Grande has 161 calories with 5.6g of fat, well below the whole milk version’s 213 calories. This is a guaranteed lactose-free pour, not a workaround, so you get the same matcha flavor with confidence about the milk.
Sugar and protein stay nearly identical to the low-fat build, since the lactose-free carton Starbucks uses is nutritionally close to standard low-fat milk once the lactose is removed.
