How long does a typical espresso shot take to brew?

A typical espresso shot takes 25-30 seconds to brew, which aligns with the correct answer. This brewing time is critical for achieving the optimal extraction of flavors from the coffee grounds. If the shot is brewed for too short a time, the result may be under-extracted, leading to a sour taste as the sweeter and fuller flavors have not had enough time to develop. Conversely, if brewed for too long, the espresso can become over-extracted, resulting in a bitter flavor due to excessive extraction of undesirable compounds.

Timing is also essential because espresso relies on the pressure of hot water passing through finely-ground coffee. This process is designed to create a concentrated shot with a rich crema, which is the golden foam that sits atop a well-extracted espresso. Mastering the timing of brewing is a vital skill for baristas to ensure consistency and quality in every cup served.
