Background technique

In daily life, coffee has become a refreshment and a common drink for the general public. Not only that, drinking coffee has become a fashionable representative of the urban style, and has become an important communication activity in life. It seems to be a synonym for savoring the good times of life and the joy of leisure life. In addition, purchasing good coffee is only the first step in making good coffee. Correct storage, grinding, temperature of water during brewing, and contact time with coffee powder are all important factors that affect the quality of coffee brewing. Coffee brewing methods are generally classified into the following categories: (1) Filter Coffee, (2) Napoletana, (3) Siphon, (4) Mocha ), (5) Italian brewing method (Espresso), (6) Evelik brewing method (Turkish lbrik Coffee).

If filter coffee is taken as an example, use your hands to stretch the filter paper into a funnel shape, put the filter in the filter, stick it flat on the filter, take an appropriate amount of coffee powder, place it on the filter paper, pick up the filter and pat the filter with your palm , so that the coffee powder is relatively solid due to the vibration of the tap. Then put the colander back on the colander. Pour a small amount of boiled water into the glass pot to warm the pot, shake the body of the pot to make the temperature of the glass pot rise, pour out the water in the pot, and place the filter filled with coffee powder on the top of the glass pot. One cooling is to put the kettle on a wet towel and add cold water to the boiling water to cool down for a few seconds, and the water temperature drops to 93°C. Then, start from the center of the filter with a very fine water flow to spiral outwards, and then repeatedly rotate in the same direction from the outside to the inside, the water flow is stable and uninterrupted. The amount of water should be just enough to wet the coffee powder, and stop when about 3 drops of water drip into the glass pot. The coffee powder will expand due to water absorption and emit an aromatic smell. This step is called steaming. After steaming, put the kettle on the wet towel to cool down for a few seconds to cool down for the second time. The water temperature drops to about 91°C, which is the most suitable for brewing coffee. According to the method of steaming and flushing, the water flow can be thicker. Rotate the circle to inject an appropriate amount of water, and the water level just reaches the edge of the filter. Finally, when the water is poured into the center of the circle, the water is collected, and the brewing is completed. The biggest skill of brewing filter coffee is to control the thickness and stability of the water flow. The stable and moderate water flow spirals outward from the center of the filter, just like a stirring rod evenly stirring the coffee powder and hot water.

However, if ordinary people want to pour hot water on the coffee powder in a stable and uniform manner at the same time in a spiral motion, they need to practice for a long time. It is really difficult to find orthodox and authentic delicious coffee in which coffee beans are freshly ground into coffee powder.
