The Espresso Workflow: A Repeatable Sequence

Consistency is the foundation of good espresso. The fastest way to get consistent shots is to do every step in the same order every time.

Most of what separates a great espresso from a mediocre one isn't equipment or technique — it's consistency. The same dose, the same distribution, the same tamp, the same timing. The fastest way to get consistent shots is to do everything in the same order, every time.

The Standard Sequence

Here's a workflow that works for nearly any home setup. Adjust to your machine, but keep the order consistent.

1. Turn the machine on and let it fully warm up. Warm-up time varies significantly by machine type. Thermocoil machines like the Breville Bambino or Barista Pro are ready in seconds. Single-boiler machines typically need 10 to 15 minutes. Prosumer machines with large brass groups — E61 machines, heat exchangers, dual boilers — need at least 20 minutes for the group to fully stabilize sometimes more. Refer to your manual for warm-up time. Keep the portafilter locked in the group during warm-up so it heats with the machine, not on the cold countertop.

2. Flush the group head. Run a short flush through the group to purge any standing water and bring the group to brew temperature. How you do this depends on your machine — some workflows flush with the portafilter locked in (then remove, wipe, and dose), others flush with the portafilter out while the puck prep is already done. Check your machine's recommended workflow. Either way, a flush just before dosing and locking in ensures you're starting at a consistent temperature.

3. Remove the portafilter and wipe the basket dry. A wet basket causes grounds to clump against the sides unevenly, which leads to channeling. Wipe thoroughly with a clean, dry towel.

4. Dose. Weigh your dose with a scale. Don't guess — even a half-gram difference is detectable in the cup. A good starting point for a double shot is 16 to 18g, though the right dose depends on your specific basket, grinder, and coffee. Adjust to match your basket's usable capacity and your target ratio.

5. Distribute. If you prefer, use a WDT tool or your preferred distribution method to eliminate clumps and level the surface. Uneven distribution before tamping is one of the most common sources of channeling. This is an optional step but can be an easy addition to help consistency. 

6. Tamp. Flat, level, and firm — around 30 lbs of pressure is the standard reference point. Consistency matters more than the exact number. A calibrated tamper that clicks at a set pressure removes this variable entirely.

7. Wipe the rim of the basket. Stray grounds on the rim interfere with the group gasket seal and can cause bypass around the puck.

8. Lock the portafilter in immediately. Don't let it sit on the counter while you do other things — the puck and portafilter are losing heat the moment they leave the group.

9. Place your cup on a scale, tare to zero, start your shot, and start a timer. Watch the shot and stop the pump when you reach your target yield. A standard double is a 1:2 ratio — 18g in, 36g out — pulled in roughly 25 to 30 seconds, though your coffee and preference will guide your target.

Why Order Matters

Most workflow problems come from steps out of sequence. Tamping before distributing locks in clumps. Letting the portafilter sit after locking it in drops the group temperature before the shot even starts. Skipping the flush leaves stale or off-temperature water in the lines. Dosing into a wet basket sets up uneven extraction. Each step exists for a specific reason.

Once the sequence is fixed and consistent, dialing in becomes a matter of changing one variable at a time and tasting the result — instead of wondering what might have been different from yesterday's shot.

Tracking What Works

Write down your recipe — dose, yield, time, grind setting. When you find a shot you love, you should be able to pull it again tomorrow. A small notebook or notes app saves a lot of frustration. The dose and grind size articles in our dial-in series walk through how to adjust each variable if your shots aren't landing where you want them.
