Setup
First Shots: What to Expect From a New Espresso Machine
Your first week with a new espresso machine is a calibration period for you and the equipment together, not a test of the machine alone.
Expect inconsistency at first
New burrs, an unfamiliar grinder dial, and your own unfamiliarity with the machine's quirks all add variance to early shots — this is normal and not necessarily a defect. Some grinders also have a short "burn-in" period where the first sessions of grinding wear in the burrs slightly, changing output subtly over the first several uses.
Change one variable at a time
When a shot tastes off, resist changing grind, dose, and tamp all at once. Adjust one variable, taste, and adjust again — otherwise you cannot tell what fixed (or broke) the shot, and you end up chasing a moving target instead of converging on a recipe.
Keep notes for the first couple of weeks
A simple log of grind setting, dose, shot time, and yield for your first shots turns trial-and-error into a repeatable recipe much faster than memory alone. Even a plain notes app entry after each shot — "18g in, 36g out, 27 seconds, tastes sour" — is enough to spot a pattern within a few days that pure memory would miss.
What genuinely bad first shots usually mean
If shots are dramatically off — near-instant flow with almost no resistance, or the pump straining with no flow at all — that is more likely a setup issue (see our setup guide) than a technique problem: check priming, grind size at the extremes of your grinder's range, and that the portafilter is locked in fully before assuming the equipment itself is at fault.
