Espresso is a brewing method, not a bean or roast. It's concentrated coffee made by forcing hot water through finely ground coffee under high pressure.
Pressure: 9 bars pressure extracts quickly and creates crema (golden foam on top). Regular coffee uses gravity, no pressure.
Concentration: Espresso is about 10x more concentrated than drip coffee. Thicker, more intense flavor.
Serving Size: 1-2oz for espresso vs 8-12oz for regular coffee.
