Any of Starbucks' popular drinks can be customized with extra syrups, flavorings, and milk replacements, but some other add-ins aren't as self-explanatory, like cold foam and sweet cream. While cold foam and sweet cream are similar, they have differences in how taste, how they're made, and how they're used in drinks.

Cold foam is a drink topping that is made by blending cold nonfat milk to create a velvety texture and flavor without using any cream. Cold foam holds its shape better than hot foam, while it's an essential part of drinks like the Cold Foam Cascara Cold Brew, it can be added to any cold or hot drink via customization.

Meanwhile, Starbucks’ sweet cream is a vanilla-flavored, high-fat cream product made with 2% milk, heavy whipping cream, vanilla syrup, and added sugars, giving it a sweet, syrupy flavor. While cold foam sits on top of your drink, sweet cream is mixed directly into drinks such as the Vanilla Sweet Cream Cold Brew.
