How to Pull an Espresso Shot
Pulling a shot takes less than a minute, but every step before you press the button affects what ends up in the cup. Here’s the routine I use every morning, broken down so you can copy it and adjust from there.
Before You Start
Turn the machine on early. Most home machines need 15 to 30 minutes for the group head and portafilter to reach a stable temperature. A cold portafilter pulls heat out of the water and can leave you with a sour espresso shot even when your grind is right.
While it warms up, check your beans. Coffee that’s a week or two past its roast date works well. Beans that are too fresh can be gassy and erratic, and beans that are two months old will taste flat.
Step 1: Weigh the Dose
Put the empty portafilter basket on a coffee scale and tare it. Grind your coffee and weigh it. For a standard double basket, 18 grams is a good default.
Weighing every time sounds tedious, but it removes one variable completely. If the shot is off, you know the dose wasn’t the cause.
Step 2: Distribute and Tamp
Break up any clumps with a thin needle tool or by gently tapping the side of the portafilter. You want an even bed with no high or low spots.
Then tamp. Hold the tamper like a doorknob, keep your wrist straight, and press down until the coffee stops compressing. Our espresso tamping guide covers this in more detail, but the short version is: level matters more than force.
Step 3: Flush and Lock In
Run a short flush of water through the group head for two or three seconds. This clears old grounds and stabilizes the temperature.
Lock in the portafilter, place your cup on the scale underneath, tare it, and start the shot right away. Leaving the coffee sitting in a hot group head can start to cook it.
Step 4: Watch the Flow
For the first few seconds, nothing much should happen. Then dark drops will appear, followed by a steady stream that looks like warm honey. As the shot goes on, the color lightens from deep brown to tan.
Signs of trouble:
- Fast, pale, watery flow from the start usually means your grind size is too coarse
- Barely any drips after 15 seconds usually means the grind is too fine
- Spurting or a stream from one side points to channeling and uneven puck prep
Step 5: Stop at Your Target Yield
Stop the shot when the scale reaches your target. With an 18-gram dose and a 1:2 brew ratio, that’s about 36 grams. Note the time. Somewhere between 25 and 32 seconds is a reasonable window for most medium roasts.
Espresso shot timing is a guide, not a rule. A shot that runs 34 seconds and tastes great is a good shot.
Step 6: Taste and Adjust
Stir the espresso before tasting so the crema and liquid mix. Then ask yourself one simple question: is it sour, bitter, or balanced?
- Sour and thin: grind finer
- Bitter and drying: grind coarser
- Weak but balanced: try a slightly higher dose or a shorter ratio
This loop of adjusting and tasting is what people mean when they talk about how to dial in espresso. Make one change per shot and keep notes.
Clean Up Right Away
Knock out the puck, rinse the basket, and wipe the group head gasket. Old coffee oils go rancid quickly and will show up as off flavors in tomorrow’s shot. A clean routine also slows the buildup that eventually means you’ll need to descale your espresso machine.
