How to make espresso with all kinds of coffee machines

What do you mean to make coffee? Of course, it is not to boil the coffee beans in boiling water, in that case, you will only get a cup of scorched bitter water, which tastes bitter and astringent, so how can you enjoy the fragrance of the coffee? People who pay attention to enjoying life love to buy a coffee machine to go home and cook and sigh, but not many people really know how to cook. Back to the point, pay attention to a few questions before making coffee: determine the size of the coffee you want to grind to choose a coffee machine; use 92-96 degrees Celsius for water; and pay attention to different cooking times.

If you buy a small household coffee machine, that is, the kind of coffee that goes through a filter paper or gold filter, pay attention to the use of the small funnel: put a piece of filter paper on the inside of the funnel and put 8 grams of coffee powder into the filter paper pocket. (to prevent coffee from entering the interlayer between the filter paper and the funnel wall) wet the coffee powder with water at the right water temperature, and then add water later (water should be added slowly to prevent the coffee dregs from rushing into the coffee above the edge of the filter paper) until a good cup of coffee is poured out.

In the case of an electric drip coffee machine, preheat the coffee machine before making coffee every day, add half a pot of water to the sink, turn on the power, top out the stale water in the machine, then clean the boiler and the pipes of the cooking system, clean the coffee funnel, and finally preheat the coffee pot. Put a matching filter paper in the coffee machine funnel, press each cup of 7g coffee powder into the filter paper (be careful when the coffee powder enters the filter paper and the funnel wall), and close the funnel door. Add water into the tank according to the standard of 175 ml per cup and turn on the power supply. The result is a moderate fineness of coffee powder.

Coffee maker is a traditional soaking method, coffee powder and brewed coffee liquid are in the same container, this method can taste the advantages and disadvantages of coffee. In practice, the coffee powder that matches the thickness of the press pot should be put into the pot according to the amount of (8g / 10g) cup, but it should not exceed the limit of the coffee pot. Pour water from 91 to 96 degrees Celsius into the pot until the top of the metal rack outside the coffee pot, place the filter rod, soak for 3 minutes, push the filter to the bottom, and a pot of delicious coffee is ready.

There are several problems that should be paid attention to in this method:

First, the choice of coffee pot. As the current coffee cultural atmosphere is still in the slow development stage, the coffee brewing equipment market is not very sound, when buying, we must pay attention to the glass of the coffee pot, its thickness should be uniform, the bucket is vertical, the caliber is the same, and the metal shelf outside should be strong and hard.

Second, water temperature. Too high water temperature will make the oil quality of coffee bad, make coffee bitter, too low water temperature can not boil coffee taste, coffee will be sour and astringent. So the normal water temperature should be between 91 and 96 degrees Celsius.

Third, the degree of coffee powder grinding. This is a soaking method, which takes 3 minutes to soak, so the coffee powder should be coarse.

Fourth, downward pressure. Press the pressure bar with the palm of your hand and apply it vertically and uniformly down to the bottom of the pot. Remember to push evenly, too hard will burst the coffee pot.

Fifth, coffee powder can not be boiled again. It is standard to cook delicious coffee for the first time and bad water for the second time. Any kind of coffee is made by washing the flavor out of the coffee powder with water, and the second time it is tasteless.
