What is the ideal dose of coffee to use for a single shot of espresso?

For a single shot of espresso, the ideal dose of coffee to use typically falls within the range of 7 to 9 grams. This dosage is crucial because it directly affects the extraction process, flavor profile, and overall quality of the espresso shot.

Using between 7 to 9 grams allows for optimal extraction of the coffee oils, flavors, and acidity that define a well-balanced espresso. Too little coffee (less than 7 grams) may lead to under-extraction, producing a sour or weak shot. Conversely, using more than 9 grams risks over-extraction, which can result in bitterness and undesirable flavors.

By adhering to the 7 to 9 grams guideline, baristas can achieve the desired strength and flavor complexity for a single shot of espresso, making this range the industry standard for high-quality espresso preparation.
