The knowledge of coffee and milk foam

Last updated 2026-09-29 — Milk should be refrigerated with fat content above 3.5, and very cold milk should be used. After hitting the foam, let the delicate and rough foam separate, scrape off the top rough foam, and the rest of the delicate foam can be used to make Latte art. The finer and denser the foam is, the longer it stays, the easier it is to pull flowers.
