When making espresso, it is generally worth considering these things:
- Coffee weight
- Coffee grind fineness
- Water temperature
- Amount of pressure (which you can even adjust while brewing)
- Weight of coffee prepared
- Brewing time
This may seem very complicated at first glance, so let's simplify it a bit. We'll assume that you only have a basic espresso machine at home, which doesn't allow you to change the pressure and water temperature.
