Let’s make coffee.

  1. 01

    Grind and dose

    Grind 19 g of coffee fine and add it to a clean, dry portafilter basket. Use a dose appropriate to your basket if 19 g does not fit.

  2. 02

    Distribute

    Spread the grounds evenly across the basket before applying pressure.

  3. 03

    Tamp

    Keep the tamper level and apply pressure until the coffee bed is compressed.

  4. 04

    Lock in the portafilter

    Insert it securely into the machine without knocking or disturbing the coffee bed. Put your cup on the scale underneath and tare it.

  5. 05

    Brew and weigh

    Start the shot and timer. Use about 30 seconds as the app’s starting time, and 38 g of espresso as the output target for a 19 g dose at 1:2. Stop the shot at your target yield and taste.

Yield is coffee in the cup

The 38 g figure is espresso output, not water to add to the machine. It is calculated from the app’s 19 g dose and 1:2 ratio; the built-in timed step itself runs for 30 seconds.
