The trickle coffee machine in the United States adopts a very simple method, which allows hot water to directly pass through coffee powder and extract it in a trickle way. The biggest difference with italian coffee machine is that there is no high pressure. Considering the difficulty of operation, it is recommended to buy an American drip coffee machine.

The second step is how to make coffee without adding coffee beans and buy high-quality coffee beans.

Coffee beans must be fresh, and only freshly roasted coffee beans can make coffee rich and mellow. When buying, you should also pay attention to whether the color and particle size of beans are uniform. Good coffee beans not only have a shiny appearance, but also have a strong aroma and no odor. It is best for netizens to buy some freshly roasted coffee beans at a place near their home or to buy freshly roasted coffee beans at a well-known online shop.

Third, grind coffee powder.

For the average family, 1-2 cups of coffee can buy a nice hand-cranked bean grinder. Hand-operated bean grinder is cheaper and more fun than electric bean grinder, which may be more suitable for coffee shops. When is the best time to grind coffee beans? Grind them before cooking. Because ground coffee is easy to oxidize and lose its fragrance, especially in the absence of proper storage, coffee powder is easy to taste, and naturally it is impossible to make mellow coffee. There are various brands and models of coffee grinder, and it is ideal to adjust the thickness of beans.

Step four, pay attention to the water used to make coffee.

Just as water is essential for making tea, water is also essential for extracting coffee. Natural water includes spring water, river water, well water, lake water and rain water, which are too hard to extract coffee. The best way to make coffee is to purify soft water, such as boiled water. The water used for making coffee is generally 90-92 degrees. Some coffee brewed with too hot water will taste burnt. In the process of brewing, water permeates into coffee particles and diffuses.

Step five, start making coffee powder. It is most important to control the contact time between coffee powder and water, and pay attention to filtration.

The powder/water ratio of American trickle coffee machine is generally 1 g coffee powder mixing 10- 15 ml water. The normal size of a cup of coffee is 200-300ml, which can be made of 20g coffee powder. To use the American drip coffee machine, you must first preheat the coffee machine; Second, add half a pot of water into the sink, and after turning on the power supply, push out the stale water in the machine; Thirdly, clean the pipes of the boiler and the brewing system, clean the coffee brewing funnel, and finally preheat the coffee pot; Fourth, put a matching filter paper in the funnel of the coffee machine, put coffee powder into the filter paper according to your favorite powder-water ratio (pay attention to the coffee powder entering the interlayer between the filter paper and the funnel wall), and close the funnel door; Fifth, after adding a corresponding amount of water into the water tank, the boiled water will flow out in about 10 second after the power is turned on, and the work will be completed in 5-8 minutes.

Step six, choose a coffee cup you like, and prepare to taste it, or match it with some snacks.

The best drinking temperature of coffee is 85-88 degrees Celsius. The color of coffee cup is very important, and the color of coffee liquid is amber and very clear, so in order to show the characteristics of coffee, it is best to use a coffee cup with white inside. Generally, you can choose bone China cups for drinking coffee. The bone China cup is exquisitely made, transparent, light and delicate in appearance. Using this bone China cup with animal ashes in the texture can slow down the temperature of coffee in the cup. As for snacks with coffee, there are biscuits, cream cakes, chocolate cakes (brownies, tiramisu), cheesecakes, pies and so on. If you are particular, when drinking plain coffee (pure American), try to match it with some milk-flavored cakes (cheese or cream), and cookies are also acceptable. When drinking fancy coffee (latte), you can try some cakes without milk, such as brownies. However, the matching snacks are not absolute, and they should be chosen according to personal taste.
