If the double shot pulls slowly, grind size is?

• A. Grinds are too coarse
• B. Temperature is off
• C. Dosing is too low
• D. Grinds are too fine

Answer: (D)

When a double shot pulls slowly, the water is meeting more resistance in the coffee bed. The grind size directly controls that resistance: a finer grind increases surface area and tightness of the puck, making water flow through more slowly and extending extraction time. If the grind were too fine, you’d see a slow pull like this; a grind that’s too coarse would let water pass quickly and the shot would pull faster and under-extract. Temperature or dosing can influence flavor and flow, but the symptom described points most to the grind being too fine, so moving toward a coarser grind usually helps restore the proper pull.
