The Golden Layer on Top of Espresso
Updated: July 2026 โข 8 min read.
Crema is the golden-brown foam that forms on top of freshly brewed espresso.
It is created when hot water under pressure emulsifies coffee oils and releases carbon dioxide trapped inside freshly roasted coffee beans.
Good crema can indicate freshness, proper extraction, and balanced espresso brewing.
