Why Your Cold Foam Disappears and Latte Art Won't Pour

Cold milk foam collapses quickly or stays too stiff to pour because of how fat, protein and temperature interact during preparation. The same physics that make foam stable also decide whether the surface stays smooth enough for latte art. This educational food-science explainer describes principles supported by the reviewed sources. It is not personalized nutrition advice or a substitute for official food-safety, label, tested-recipe, manufacturer, or local regulatory guidance.
