Good foam isn’t luck — it’s technique. A few minutes of practice make the difference between dense, velvety microfoam and big, hollow bubbles.
Start with cold, fresh milk
Cold milk gives you more time to build the foam properly before it reaches temperature. Full-fat milk foams more stably than skim, thanks to its fat content.
Where to position the wand
Submerge the steam wand just below the surface, at a slight angle, so a whirlpool forms — that whirlpool breaks big bubbles down into microscopic ones.
Two phases: air, then whirlpool
For the first few seconds, keep the wand closer to the surface to "stretch" air in — you’ll hear a distinct sound. Then submerge it a bit deeper and let the whirlpool work until 60–65°C.
How to know when to stop
Touch the pitcher — once you can’t comfortably hold it anymore, the milk is ready. Tap the pitcher lightly on the counter and swirl it, to pop any large bubbles left over.
