How To Use An Espresso Scale For The Perfect Shot

Understanding your scale's features is just the first step. Now we apply that knowledge to a practical, repeatable brewing routine. You will move from hoping for a good shot to knowing how to achieve it.

Follow these steps to create the perfect shot:

Step 1: Prepare Your Scale And Tare The Portafilter

Place your scale securely on the machine's drip tray. Position your empty portafilter on the scale's center. Press the tare button to reset the weight display to zero. This ensures you measure only the coffee grounds, not the portafilter.

Step 2: Measure And Grind Your Coffee Dose

Grind your coffee beans directly into the portafilter on the scale. Watch the display until you reach your target dose weight. A typical starting dose is 18 grams of coffee. This precision is the foundation of your entire espresso recipe.

Step 3: Tare The Scale Again And Start The Timer

After distributing and tamping your grounds, place your cup on the scale. Tare the scale once more to zero it with the cup in place. Start extraction; the scale’s timer will activate or start it manually. This begins tracking your extraction metrics.

Step 4: Monitor The Yield And Stop The Shot

Watch the scale's display as espresso flows into your cup. Stop the extraction when you reach your target beverage yield. A common starting yield is 36 grams for an 18-gram dose. Note the final time and weight to evaluate and replicate the shot.

Note: The weight may jump initially during pre-infusion.

Following a structured method eliminates variables and builds your expertise. Each step provides specific feedback you can use for refinement. Consistency in your process leads directly to consistency in your espresso.
