Multiple outlets report that “cold foam” coffee drinks are becoming widely available across Sydney. The articles describe a range of styles sold by cafes rather than a single standard recipe. Some drinks feature an iridescent, citrus-infused bubble used as a garnish, creating a visually distinctive finish. Other versions use a thicker, creamier foam topping and are served over cold brew coffee. One outlet also likens a particular serving style to a “Mont Blanc,” indicating a dessert-like, layered presentation in at least some venues. While details differ from place to place, the sources converge on the idea that cafes are expanding their cold beverage menus around foam-topped coffee preparations. The overall coverage is presented as a guide to where shoppers can find notable examples, focusing on how different cafes customize the foam—through citrus flavours or thicker, cream-based textures—while keeping the core concept of cold brew with a foam layer.
