How do coffee beans make coffee?

To put it simply, the coffee beans are ground into powder and then boiled with a coffee machine. there are many ways to grind and cook, and they are also quite exquisite. There are several points to pay attention to when making coffee at home: 1. The degree of grinding of coffee is determined by the coffee equipment you choose. Because different coffee making methods require different grinding thickness 2. Use 92-96 degrees of water. three. Different production methods require different cooking times with small household coffee machines-coffee is made through filter paper or gold filter Filter Coffee 1, the use of a small funnel: put a piece of filter paper on the inside of the funnel and put a cup of coffee powder (8-10) 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 flushing into the coffee above the edge of the filter paper) until a cup of coffee is intact. 2. Electric drip coffee machine: preheat the coffee machine before making coffee every day, add half a pot of water in the sink and turn on the power; first, pour out the stale water in the machine; second, clean the boiler and the pipes of the cooking system; third, clean the coffee funnel; fourth, preheat the coffee pot. Put a matching piece of filter paper inside the funnel of the coffee machine, press each cup of 7-9 grams of coffee powder into the filter paper (be careful that the coffee powder enters the filter paper and the funnel wall), and close the funnel door. Press 175 ml per cup to add to the sink and turn on the power supply. Thickness of coffee powder: through filter paper or pot filter: moderate coffee maker (also known as tea maker or press pot) French Press Coffee this is a traditional soaking method, coffee powder and brewed coffee liquid in the same container, this method can taste the advantages and disadvantages of coffee. Practice: put the coffee powder that matches the thickness of the press pot into the pot according to the amount of (80.0g) cup, but do 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 and push the filter to the bottom. A pot of delicious coffee is ready. Avoid problems: first, the choice of the coffee pot: according to the current coffee cultural atmosphere is slowly developing, the coffee brewing equipment market is not very sound, when buying, we must pay attention to the uniform thickness of the glass of the coffee pot, the cup and bucket is vertical, and the caliber is the same. The metal shelf outside should be strong and hard. Second, water temperature: too high water temperature will deteriorate the oil quality of coffee, make coffee bitter, too low water temperature can not boil coffee taste coffee will be sour and astringent. So the normal water temperature is 91-96 degrees Celsius. Third, coffee powder grinding thickness: this is a soaking method, need to soak for 3 minutes, so coffee powder should be coarse. Fourth, downward pressure: you need to make this action carefully, press the pressure bar with the palm of your hand, and apply it vertically and uniformly down the bottom of the pot. Remember to push evenly, too hard will burst the coffee pot. Fifth, coffee powder can not be boiled twice: the standard first cooking, brewing delicious coffee, the second time is bad water. Any kind of coffee is made by washing the taste of coffee (water-soluble and insoluble organic and inorganic substances) out of the coffee for the second time. The thickness of coffee powder: coarse type. When brewing coffee, you should pay attention to the following points-boiling will make the coffee bitter, so do not boil the coffee. The appropriate brewing degree should be slightly less than 96 ℃. Coffee can not be reheated, when brewing, you should pay attention to only the amount needed for each time, and it is best to drink it when it is just cooked. The best drinking temperature for coffee is 85 ℃. Water accounts for 98% of a cup of coffee, so it is best to use filtered water to brew coffee, especially not chlorinated water. Do not repeat the use of coffee residues, the brewed coffee grounds leave only an unpleasant bitter taste. Make the correct coffee grinding according to the coffee maker used. Too fine grinding will make the coffee more bitter and it is easier to block the coffee maker. If the grinding is too rough, the coffee will be tasteless. In the case of filter flushing, properly ground coffee powder should be dripped for 2 to 4 minutes each time-2 tablespoons round tablespoon coffee powder / 6 ounces of water
