Brewing espresso involves forcing hot, pressurized water through finely-ground coffee. Dedicated espresso machines are designed specifically for this process, offering precise control over water temperature, pressure, and extraction time. However, some coffee machines incorporate features that allow for espresso-style brewing, albeit with varying degrees of success in replicating true espresso quality. These often involve specialized filter baskets or pods and attempt to generate higher brewing pressure than standard drip brewing.
The desire for espresso-like coffee at home stems from the rich, concentrated flavor and crema characteristic of properly pulled espresso shots. Being able to prepare these beverages without specialized equipment expands the range of coffee experiences available to consumers. Historically, espresso brewing was confined to cafes and restaurants due to the cost and complexity of the necessary machinery. The integration of espresso-style brewing into more common coffee machines reflects the growing demand for higher-quality coffee at home.
