To make perfect espresso, you can't milk it repeatedly and mix it with coffee beans to make coffee.

1. Make sure the handle and filter bowl are at high temperature.

A cold handle and filter bowl can completely ruin a good cup of coffee. The handle and filter bowl will directly affect the temperature of coffee extraction. If the temperature is too low, the coffee will not be fully extracted, and the temperature of the Italian espresso will become lower, thus affecting the overall coffee experience. In addition, be sure to wipe or clean the filter bowl before making coffee, and clean the sticky coffee powder the last time to keep the coffee powder fresh. If not cleaned in time, sticky old coffee powder will directly affect the quality of coffee.

two。 Proper preservation of coffee beans

The storage of coffee beans is essential to the quality of coffee. If you put the coffee beans directly on the coffee machine or in the overheated kitchen, the coffee beans will deteriorate quickly and the coffee will taste bitter. Be sure to keep the coffee beans in a cool, dry environment. When using coffee beans, do not pour too many beans in the bean grinder at a time, and try to make sure the coffee beans used each time are fresh enough. In addition, it is necessary to ensure that the bean warehouse is clean. The remaining coffee beans secrete oil in the bean barn. After the oil goes bad, it will be attached to the bean warehouse, affecting the quality of coffee.

3. Grind only ration coffee powder at a time

It is best to use a quantitative grinder without a powder cartridge. If the bean grinder comes with a powder compartment, be sure to clean up the remaining coffee powder after each use. In addition, the grinding of the bean grinder should be controlled manually. The use of automatic grinding will produce excess coffee powder, resulting in waste.

4. Clean up the remaining coffee powder at the outlet

Every time you remove the handle, press the outlet button in time to clean the remaining coffee powder glued to the outlet.

5. Clean the steam rods from the inside out

Clean the steam stick before each milking and release a small amount of steam to remove the remaining milk. Wipe the steam stick in time after use to prevent it from breeding bacteria and affecting the quality of milk.

6. Preheat coffee cup

Good coffee can not be put in cold cups, otherwise the quality of coffee can not be guaranteed. Most Italian espresso machines have preheating trays on top.

7. Don't repeat the milk.

According to the needs of each cup of coffee, only a moderate amount of milk is handed out at a time. Never repeatedly dispose of the milk, or pour fresh cold milk into the heated milk. In the heating process, the protein in the milk will be broken down, making the milk taste more silky. Repeatedly tossing the milk will make the coffee taste gone. It should be noted that soy milk or other vegetable protein milk should not exceed 65 ℃, otherwise the texture of the milk will not be guaranteed.

8. Be sure to keep the milk in the refrigerator

Milk with a lower temperature tastes better. If the milk is stored at room temperature, the milk will deteriorate faster and taste sour, thus affecting the overall quality of coffee.

9. Be sure to hold the milk jar by hand when milking

The right way to get rid of is an important guarantee for all high-quality milk-based coffee. If you put the milk tank directly under an unattended steam bar, you will never be able to make high-quality milk-based coffee. All trained baristas hold their hands to determine whether they reach the ideal temperature of 63-65 ℃ when handing out milk.

10. Check the quality of the coffee through the appearance after the production is finished

The surface of good Italian espresso is smooth and smooth with even grease. If coffee doesn't look perfect, its taste must be flawed.

11. Clean up all utensils and coffee machines in the work area every day

Follow the cleaning instructions provided by the coffee maker. Use the right chemicals and utensils to clean the coffee maker every day. If the coffee machine is not cleaned regularly, the quality of the coffee is not guaranteed and the coffee machine itself will be seriously damaged.

twelve。 Standardization of coffee grinding and production process

Use electronic scales with accurate readings and coffee cups with accurate capacity to make coffee. Ensure that the amount of powder, water and total weight of each cup of coffee are consistent. Once a certain parameter changes, the quality of coffee will be affected. In addition, to ensure the lasting stability of the water temperature. Professional baristas will not use hot water above 93 ℃ to make coffee. If the water temperature is too high, the coffee will have a charred taste and the quality is very poor.

13. Use filtered water

Filtered water is not only of better quality, but also protects your coffee maker from scale, affecting flow speed and steam pressure. In addition, the filter element of the filter should be changed regularly.
