1, the first step is to buy an American drip coffee machine for home use. Electric coffee machines used at home are generally divided into two forms, semi-automatic italian coffee machine and American drip coffee machines. When selecting italian coffee machine, the most important thing is the stability of extraction, including the stability of pressure and water temperature. When selecting, the stability of coffee machine extraction can be judged by the appearance of finished coffee. You can see that there is a very rich and stable layer of coffee grease on the surface of coffee, and you can judge the coffee machine by these. The oil is not particularly obvious or dissipated badly, indicating that the extraction state of this cup of coffee is not particularly ideal, indicating that the performance of this coffee machine is not very good. Semi-automatic italian coffee machine, this needs to be specially equipped with a bean grinder suitable for grinding espresso. The modes of automatic italian coffee machine are all set and made by machines, so drinking different flavors of coffee may be restricted. 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.
Step 2, buy some high-quality coffee beans. Coffee beans must be fresh, and only freshly roasted coffee can have a strong fragrance. 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. It is difficult to bake at home, so netizens generally don't have to try. If you are really a coffee lover, you can buy a adzuki bean roaster and try it. )
Step 3, grind your own coffee powder at home. Generally speaking, for a family with 1-2 cups of coffee, you can buy a good hand-cranked bean grinder. Hand soymilk machine is cheaper and more fun than electric soymilk machine, and it is suitable for coffee shops. The ideal time to grind coffee is to grind it before boiling. 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 bean grinder for grinding coffee, and it is ideal to adjust the thickness of beans.
4, the fourth step, the water used for coffee is really particular. 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 5: 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. In an espresso machine, 7-8 grams of coffee powder is used to make about 30 ml of coffee liquid (so-called espresso), and the time should be controlled within 20-30 seconds. Netizens can find the right proportion of powder and water in these ranges and get their favorite taste. 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.
6, the sixth step, choose a coffee cup you like, ready to taste, or 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.
