What is the total water volume for a traditional double Lungo shot?

A traditional double Lungo shot is characterized by a longer extraction time than a regular espresso shot, which results in a larger volume of brewed coffee. Typically, the water volume used for a double Lungo shot ranges approximately between 100-120ml. This higher volume is due to the process of extracting more flavors and compounds from the coffee grounds, as the water is allowed to flow through them for a longer duration compared to a standard espresso.

In contrast, a regular double espresso typically yields about 60ml of liquid, making the Lungo's volume significantly higher to accommodate its distinct preparation method and resulting flavor profile. Understanding the precise volume is crucial for baristas, as it influences the balance and flavor extraction of the final beverage, highlighting the importance of precise measurements in coffee preparation.
