Milk & latte art
Microfoam
Microfoam is steamed milk with very small, uniform bubbles that create a glossy, paint-like texture. It's the milk texture baristas pour for latte art — smooth enough to pour through the espresso surface and create patterns rather than mounding on top.
Microfoam is created by steam-aerating milk briefly, then submerging the wand to swirl and homogenize the foam into the liquid. Done right, the result is a continuous emulsion that looks like wet paint and pours like cream. Done wrong, you get either flat milk (no aeration) or bubbly milk (aerated too long, bubbles too large).
The technique: cold milk in a cold pitcher, fill to base of spout, purge wand, insert tip just below surface, stretch milk 1–3 seconds (longer for cappuccinos, shorter for lattes), then submerge wand to create a whirlpool and smooth the texture. Stop at 60°C / 140°F — milk should feel uncomfortably warm but not painful.
Microfoam matters for latte art (the texture you can pour into patterns), for cappuccino structure (denser foam that holds peaks), and for taste (well-textured milk has a sweet, creamy character that flat or bubbly milk lacks).
