Steam milk like a pro: the technique behind silky microfoam

Why does milk foam sometimes turn out dry and stiff, sometimes too runny? The answer lies in texturing. — by Dieter Eitz

The difference: frothing vs. texturing

Most beginners "froth" — they blast air into the milk until it's foamy. Pros call it texturing: the milk is set rotating and air is worked in evenly. The result is silky microfoam instead of dry soap bubbles.

Step 1: the right milk

Whole milk (3.5 % fat) is the easiest and gives the creamiest foam. For plant-based alternatives, "barista versions" (oat, soy) work much better than the standard versions.

Step 2: cold milk, clean wand

Milk straight from the fridge (4–6 °C) gives you more time to texture before you hit 65 °C in the pitcher. Briefly "purge" the steam wand before foaming to clear condensation.

Step 3: wand position

Wand tip just below the surface, slightly off-centre. That creates the whirlpool. Add air in the first 3–4 seconds by briefly lifting the tip, then drop it just under the surface for texturing.

Common mistakes

• Bubbly foam: too much air too quickly → drop the wand deeper
• Too hot: milk loses sweetness above 70 °C → stop earlier
• Not enough milk: minimum 150 ml for one cappuccino
• Dirty wand: always wipe immediately and purge briefly
