If the double shot pulls too quick, what is most likely true about the grind size?

• A. Grinds are too fine
• B. Grinds are too coarse
• C. Grind size is irrelevant
• D. The dose is incorrect

Answer: (C)

Grind size controls how much resistance water encounters as it passes through the coffee. If a double shot pulls too quickly, the grind is most likely too coarse. A coarser grind has less surface area and creates less friction, so water flows through the puck faster and the extraction time is shorter, often resulting in a thin, under-extracted shot. The remedy is to move to a slightly finer grind to increase resistance and slow the pull enough to allow flavors to develop. While dose and tamping also influence flow, the quickest way to slow a too-fast pull is adjusting the grind.
