In Italy, where the modern latte (or caffè latte) was born, they don’t really drink it after 11 a.m. It’s a morning-only ritual, and the caffeine content is kept modest—usually a single shot in a small cup. Over in Australia, the "flat white" takes center stage, packing a double shot into a smaller volume for a more concentrated buzz.
Meanwhile, in Seoul, you’ll find lattes with double shots by default, because Korean coffee culture embraces a strong, sustained energy boost. It’s a reminder that your caffeine experience is as much about place as it is about beans.
