What is the standard volume for a double shot of espresso?

A double shot of espresso typically has a standard volume of 2 ounces (60 ml). This measurement is based on the amount of water used to extract the coffee and the volume of the resulting espresso. A double shot is made by passing hot water through about 14-18 grams of finely ground coffee, resulting in a richer flavor concentration and a stronger coffee experience compared to a single shot.

In contrast, the other quantities mentioned do not match the standard expectation for espresso shots. A single shot of espresso typically measures about 1 ounce (30 ml), making the double shot, which is essentially two single shots combined, 2 ounces. Meanwhile, 4 ounces and 6 ounces would indicate significantly larger volumes than what is typical for an espresso serving. The focus on precision in espresso measurements ensures consistency in flavor and quality, which is crucial for baristas aiming to provide an exceptional coffee experience.
