What is the standard brewing time for a shot of espresso?

The standard brewing time for a shot of espresso falls within the range of 25-30 seconds. This timeframe is critical because it allows for the proper extraction of flavors and oils from the coffee grounds. During this period, the water passes through the coffee under pressure, pulling out the essential compounds that contribute to the espresso’s rich flavor and crema, the golden foamy layer that sits on top of a well-brewed shot.

If the brewing time is too short, it can lead to under-extraction, resulting in a sour taste and a lack of body in the espresso. Conversely, brewing for too long can cause over-extraction, imparting bitter flavors. Therefore, adhering to the standard brewing time of 25-30 seconds ensures a balanced and flavorful shot of espresso, which is crucial for delivering the quality expected in a café setting.
