Calories in Starbucks Signature Iced Brown Sugar Oat Shaken Espresso with whole milk run from 101 in a Tall to 156 in a Venti, only offered in Tall, Grande, and Venti sizes.
A Grande has 130 calories with 19.4g of sugar, mostly from the brown sugar syrup shaken with espresso and ice. Despite the “whole milk” label here, this drink always uses oatmilk as its finishing pour; the milk name reflects the recipe listing rather than an actual dairy option.
Fat stays low at just 2.6g in a Grande, consistent with oatmilk’s lighter profile compared to a dairy-based drink like the Caffe Misto.
