How Grind Size, Dose, and Tamping Affect Your Espresso Shot

Find out how grind size, coffee dose, and tamping pressure interact to produce a stable espresso shot, and why these factors vary by bean and machine.

If your espresso shots taste off—sour, bitter, weak, or thin—it’s likely down to one or more of three core variables: grind size, dose, and tamping. Most home and even some shop baristas tweak these blindly, unsure which change actually fixes the issue. The good news? There’s a logical system behind how these factors interact, and once you understand it, dialling in becomes far more predictable—even across different grinders or beans.
