FAQ
How is espresso different from regular coffee?
Espresso is brewed under high pressure for a short time, creating a concentrated, syrupy shot with crema. Regular drip coffee uses gravity and longer steeping, resulting in a larger, less concentrated volume.
Does espresso have more caffeine than drip coffee?
Per ounce, yes—espresso is much more concentrated. However, a standard serving of drip coffee (e.g., 8 oz) typically contains more total caffeine than a single shot of espresso (1 oz).
Why does espresso have crema?
Crema is a golden-brown foam formed when hot, pressurized water emulsifies coffee oils and releases carbon dioxide from freshly roasted beans. It's a sign of a well-extracted shot.
