Electric drip filter is commonly known as "American coffee machine". The only thing to pay attention to when buying an American coffee machine is the "wattage" that represents the horsepower of the heater in the machine. The higher the watt number, the stronger the heater horsepower, the more delicious coffee can be made.

The importance of large wattage is that machines with weak heaters cannot boil water quickly or evenly, causing the machine to start brewing coffee at a temperature that is too cold and takes too long to brew.

The most suitable water temperature for brewing coffee is 90.6-96 degrees Celsius, and the most suitable brewing time is 4-6 minutes. In a machine with weak horsepower, insufficient hot water temperature will result in insufficient coffee extraction. When the brewing time is lengthened, the coffee powder is soaked in hot water for too long, which is harmful to coffee over-extraction.

Therefore, the coffee should not only be finished as soon as possible after it is made, but also should be made as short as possible. The number of watts marked on the coffee machine is the convenient index to judge the horsepower of the heater. in order to meet the above ideal brewing conditions, at least an American coffee machine with v above 1000W should be purchased.

In order to make up for the lack of water temperature, it can be remedied by preheating the machine. That is, without adding coffee powder, first boil in a cup of water, so that you can preheat the water tank and heating pipe inside the machine, as well as the filter paper or metal filter, filter, and the coffee pot underneath. At the same time, if you choose to use filter paper, this empty boiling process is also helpful to wash away the odor of chemicals in the filter paper. The coffee will not be ground until the preheating is over. Because it takes a long time to brew and boil, a thicker ground coffee powder is needed, and a medium to coarse sugar grinding scale is more suitable.

When the preheating is complete, turn off the switch temporarily, pour the preheated water flowing into the coffee pot into the coffee cup at medium temperature, and fill with ground coffee powder. Because the preheated filter paper or metal filter is still moist, it is easy to cause the water to overflow along the wet edge, so it is important to remind you to dig a pit in the middle after filling the coffee in order to spread the water from the middle to soak all the coffee powder evenly.

Put the coffee pot back in order, fill the coffee powder, close the filter cup, and pour water into the tank before turning on the machine switch again, because the machine which is still in the state of heat engine can immediately spray out the added water and begin to brew. The electric heating plate on the lower edge of the American coffee machine looks like a thoughtful design to keep the coffee warm, but in fact, continuously heating a pot of hot coffee will not only accelerate the aroma and taste of the coffee, but also scorch the coffee at the bottom of the pot. If you can't drink the coffee as soon as it is made, there is a little secret for brewing: add only half the amount of water to the machine, take the coffee of twice the concentration off the hot plate after cooking, and add the hot water of the other half before drinking, which not only shortens the cooking time of the coffee, but also maintains the temperature and taste of the imported coffee.

Remember to rinse and use the utensils immediately after making coffee. Filter screens, filter cups, coffee pots and water outlet filters should all use hot water or neutral detergent to remove grease, and the heating pipe inside the coffee machine should also remove scale regularly. As long as the beans are fresh and the cooking process can pay attention to a few details, the American coffee machine is a good helper for busy modern people.
