Best Milk Frothers for Cold Foam: Top Picks for Iced Drinks

Our top pick is the Nespresso Aeroccino4 (our top pick), because only countertop model in this list with a purpose-built cold froth setting. The runner-up is the Zulay Original Milk Frother, followed by the Maestri House DualFro 400 Milk Frother.

For most buyers, yes. It ranks #1 in our milk frothers for cold foam research, though no manual control over whisk duration, the cold cycle runs a fixed length.

Cold foam is dense, airy foam made from cold milk (often skim or a barista-blend plant milk) without any heat, designed to float on top of an iced drink rather than mix in and melt ice. Regular hot foam, the kind on a cappuccino, is looser and dissipates quickly. Cold foam holds its shape longer because there's no heat causing the bubbles to collapse as fast, and it's typically whisked longer and harder to get a thicker, more stable texture.

A dedicated cold froth mode, like the Nespresso Aeroccino4's, is calibrated to not heat the milk at all while still running the whisk long enough to build proper cold foam density. A handheld frother (Zulay) works fine on cold milk too since it never applies heat in the first place, the technique is just to whisk longer than you would for hot foam, generally 30 to 45 seconds, to build the denser texture. Countertop frothers without a dedicated cold setting (most fixed hot-only models) will heat the milk regardless of what you want, which defeats the purpose of cold foam.

Skim or low-fat dairy milk actually produces denser, more stable cold foam than whole milk, counterintuitively, because lower fat content whisks into a stiffer structure at cold temperatures, similar to how skim milk meringues whip stiffer than cream. For plant-based cold foam, barista-blend oat milk is the most reliable option. Whichever milk is used, starting it cold from the fridge (not room temperature) produces a noticeably denser foam.

Yes, with a hand mixer, a milk frother's handheld whisk works better, but in a pinch a small hand mixer or even vigorous shaking in a sealed jar for 30 to 60 seconds can produce a passable cold foam. The result is generally less fine and less stable than a purpose-built frother, and it takes noticeably more physical effort. For anyone making cold foam drinks regularly, a dedicated handheld or countertop frother is worth the investment.
