For modern espresso, how do the grind measurements typically vary for single vs double shots?

In the context of modern espresso preparation, the grind measurements for single and double shots do indeed vary due to the different amounts of coffee used in each. A double shot typically requires more coffee than a single shot, which is reflected in the grind measurements.

For a single shot, baristas usually use around 7-9 grams of coffee, while a double shot generally requires about 14-18 grams. This increase in coffee amount for the double shot necessitates a different grind measurement, as the extraction process relies on consistent particle size to ensure optimal flavor and strength.

While some variations might occur based on bean type or specific brewing preferences, the fundamental distinction between single and double shots is the increased amount of coffee used for the latter, leading to the necessity for different grind measurements. This difference helps in achieving the desired flavor profile and intensity of espresso for each shot.
