Grinding your coffee too coarsely, using less coffee, or failing to tamp the grounds properly can result in inadequate pressure during the brew. This can lead to an under-extracted espresso, which may taste weak or bitter. To ensure the best flavor, it's crucial to achieve the right pressure.
The amount of espresso extracted will differ based on the grind size and the amount of coffee used. When you adjust these factors, you may need to reprogram your machine. This ensures that the extraction is perfect every time.
By paying attention to these details, you can enjoy a rich, flavorful espresso that meets your taste preferences.
