Microfoam

To steam milk for espresso drinks: purge the steam wand, position the tip just below the milk surface, open full steam and introduce air for 2–5 seconds (the “stretching” phase), then submerge the tip to create a spinning vortex until the pitcher reaches 140–155°F (60–68°C). The entire process takes about 30–45 seconds. Good microfoam transforms an ordinary espresso into a proper latte, cappuccino, or flat white. The goal is smooth, glossy milk with tiny, evenly distributed bubbles — not stiff peaks or large, soapy bubbles.
