Doppio

The term 'doppio' is Italian for 'double,' and in the context of coffee, it refers to a double shot of espresso. While the history of espresso is rooted in single shots, the doppio has become the industry standard for specialty coffee shops worldwide. A standard doppio is prepared by using a double-basket portafilter, which holds a larger dose of coffee—typically between 14 and 20 grams—to produce a balanced, concentrated shot of espresso.

What is a doppio in terms of volume and extraction? A well-prepared doppio should yield roughly 30 to 60 milliliters of liquid, depending on the desired brew ratio and the specific coffee being used. The goal is to achieve a balanced extraction that highlights the sweetness, acidity, and body of the coffee, topped with a rich, golden-brown crema. Because it uses a larger dose, the doppio provides a more robust flavor profile than a single shot, making it the ideal foundation for milk-based drinks like lattes and cappuccinos.

For the barista, the doppio is the primary unit of measurement for dialing in an espresso machine. By focusing on the doppio, the barista can more accurately assess the extraction yield and adjust the grind size, dose, and contact time to achieve the perfect cup. It is the standard against which all other espresso-based drinks are measured, and it is the most common way to serve espresso to customers who want to taste the coffee in its purest, most concentrated form.

In practice, ordering a 'double espresso' or a 'doppio' is the best way to evaluate the quality of a roastery's espresso blend or single-origin offering. It allows the drinker to experience the full complexity of the roast and the skill of the barista. Whether enjoyed on its own or as the base for a milk drink, the doppio is the fundamental building block of the modern espresso bar, representing the perfect balance of science, technique, and flavor.
