Calories in Starbucks Iced Matcha Green Tea Latte with semi-skimmed milk run 82 to 135 calories from Tall to Venti, identical to the low-fat listing since that’s just the British English name for the same carton.
A Grande sits at 117 calories with 10.9g of sugar, all from the pre-sweetened matcha blend rather than the milk choice.
If you’re ordering with UK milk terms, the same naming applies across the iced menu — see Iced Mocha with semi-skimmed milk for another example.
