How is cold foam created in coffee beverages?

Cold foam is created by blending milk or cream with air to incorporate air into the liquid, resulting in a light, frothy texture that can be added to coffee beverages. This process typically utilizes a milk frother or blender, which aerates the milk or cream while achieving a cold temperature. The resulting foam is stable and can hold its shape, providing a delightful texture and visual contrast when served on top of cold brew coffees or iced beverages.

Using whipped cream would not result in the same airy texture as cold foam, as whipped cream is denser and does not have the same stability when added to cold drinks. Freezing milk before blending would alter its consistency and not create the desired frothy effect. Brewing iced coffee does not relate to the creation of cold foam; instead, it involves preparing coffee in a chilled format. Thus, blending milk or cream while incorporating air is essential to achieve the desired outcome of cold foam.
