What does the shot window refer to?

• A. The time to grind the beans.
• B. The amount of time it takes for hot steam to flow through the grounds and dispense a double shot, typically 17 to 27 seconds.
• C. The duration of a milk frothing step.
• D. The time to rinse the machine.

Answer: (B)

The shot window refers to the extraction time during pulling an espresso shot—the period from when the espresso begins to flow through the grounds until the shot finishes. This window is typically 17 to 27 seconds for a double shot, and it’s chosen because, within that range, the flavors tend to balance well, giving adequate sweetness and body without under- or over-extracting. The duration is influenced by grind size, dose, tamp, machine pressure, and water temperature. If the shot runs shorter, it’s often under-extracted and weak; if it runs longer, it can become over-extracted and bitter. This concept is specific to the espresso extraction process, not to grinding time, milk frothing, or rinsing the machine.
