What is the typical serving size for a shot of espresso?

The typical serving size for a shot of espresso is 1 ounce. This measurement is standard across most coffee practices and is critical for maintaining consistency in flavor and strength in espresso drinks. A single shot of espresso is concentrated, delivering a rich and bold flavor profile that can be affected by variations in the volume of the shot. Understanding this measurement is essential for baristas when preparing espresso-based beverages, as it ensures that each drink has the right balance and intensity. Other options, such as 2 ounces, 4 ounces, or 3 ounces, represent larger volumes that are not conventionally used for a standard shot of espresso, which could dilute the desired taste experience.
