Choose appropriate ground coffee
The coffee should be freshly ground and subjected to deep roasting. You may
need to use French or Italian roasted coffee powder for espresso. Pre-ground
coffee powder can only remain scented for 7 to 8 days unless it is stored in a
sealed container and placed in a cool place. Do not store coffee in the
refrigerator or freezer. It is recommended to grind all coffee beans into
powder before use. The fragrance of the coffee beans stored in the sealed
container can be maintained for 4 weeks.
If you are grinding coffee beans for yourself, this step is a key step in the espresso making process and requires more practice. The coffee beans must be finely ground, and the adjustment knob can adjust the coarseness&fineness of ground coffee. The preset intermediate grind setting is optimal when the machine leaves the factory. When coffee ground by cutting blade becomes coarser during use, the adjustment knob can be properly rotated to make the ground coffee finer
- The ground coffee should look like salt.
- If the powder is too fine, even if it is tamped it may cause the coffee to flow out intermittently. These ground coffee feels like flour
- If the powder is too thick, the water will flow too fast, which will hinder the extraction of its rich aroma.
In order to get a uniform, consistent coffee, be sure to use a high quality coffee grinder
