Which statement best describes the shot window timing?

• A. 10-20 seconds
• B. 30-40 seconds
• C. 17-27 seconds
• D. 5-10 seconds

Answer: (C)

The timing of an espresso shot is about extracting flavors within a window that balances sweetness, acidity, and body. If the shot finishes too quickly, you’re under-extracted, yielding a sour, weak cup with little depth. If it runs too long, you’re over-extracted, pulling bitter, harsh notes and a heavy mouthfeel. The sweet spot falls around 17 to 27 seconds for a standard double shot, where the sugars, oils, and acids come out in harmony and a good crema develops. Variations in bean roast, grind size, dose, and machine can shift the ideal timing, but 17–27 seconds is the reliable target. The other options sit outside this balanced range, either rushing the extraction or dragging it out too long to produce the intended flavor.
