Fresh and moist water: Coffee is 97% water. Only with good water quality can the original aroma and richness of coffee be brewed. It's best to make coffee with filtered water. Don't make coffee, because boiling water will make coffee bitter. In addition, it should be noted that the temperature of water is slightly lower than 96 degrees Celsius.

It's best not to heat the coffee again. When brewing, you should pay attention to the amount you need to cook each time, and it is best to drink it just after cooking. The best drinking temperature of coffee is 85 degrees Celsius.

How to "make" delicious coffee at home

First of all, we will introduce what is "brewing" coffee. Boil-put things in water and boil the water with a torch. But the "boiling" of brewing coffee is the process of "washing" the taste of coffee with water of 92-96 degrees. So many people will misunderstand this word. If you really "cook" coffee in water, you will get a cup of bitter water with burnt taste, not a cup of coffee (because the temperature in the water has reached above 96 degrees). The temperature above 96 degrees can destroy the oil in coffee, and the taste is spicy and astringent.

There are several points to pay attention to when making coffee at home:

1。 The degree of coffee grinding depends on the coffee equipment you choose. Because different coffee making methods need different grinding thickness.

2。 Use 92-96 degrees of water.

3。 Different cooking methods require different cooking time.

Use a small home coffee machine-coffee should be filtered through a filter paper or a gold filter.

1, use of small funnel: put a filter paper in the funnel and a cup of coffee powder in the filter paper bag (8- 10). (To prevent coffee from entering the interlayer between the filter paper and the funnel wall) Wet the coffee powder with water at a proper temperature, and then add water (slowly, to avoid the water level being higher than the edge of the filter paper and the coffee grounds rushing into the coffee) until a cup of coffee is intact.

2, electric drop coffee machine: preheat the coffee machine before making coffee every day, add half a pot of water to the sink, and turn on the power; Firstly, the stale water in the machine is pushed out; Secondly, clean boilers and cooking pipes; Third, clean the coffee brewing funnel; Fourth, preheat the coffee pot. Put a matching filter paper into the funnel of the coffee machine, put 7-9g coffee powder per cup (note that coffee powder enters the interlayer between the filter paper and the funnel wall), and close the funnel door. Add each cup 175ml into the sink and turn on the power.

Coffee powder thickness: passing through filter paper or pot filter screen: medium.

Coffee machine (also known as tea maker or press pot) French press coffee

This 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.

Exercise: Press (8? 0 g) Put a cup in the pot, but it can't exceed the limit of the coffee pot. Pour water at 9 1-96 degrees Celsius into the pot until it reaches the top of the metal frame outside the coffee pot, put the filter rod away, soak it for 3 minutes, then push the filter rod to the bottom, and a pot of delicious coffee is ready.

Avoid problems:

First, the choice of coffee pot: According to the current coffee culture atmosphere is slowly developing, the coffee brewing equipment market is not very sound. When buying, you must pay attention to the uniform glass thickness of the coffee pot, the vertical cup barrel with the same caliber, and the metal shelf outside should be firm and have a certain hardness.

Second, water temperature: too high water temperature will worsen the oil quality of coffee and make it bitter, while too low water temperature will not make the taste of coffee sour and astringent. So the normal water temperature is 9 1-96 degrees Celsius.

Third, the thickness of coffee powder: this is a soaking cooking method, which needs to be soaked for 3 minutes, so the coffee powder should be thick.

Fourth, press down: you need to make this action carefully, hold down the pressure bar with your palm, and force it vertically and in a straight line at the bottom of the pot. Remember to apply force evenly, too hard will make the coffee pot burst. Fifth, coffee powder can't be cooked twice: the standard first time, good coffee is cooked, and the second time is rotten water. Any kind of coffee cooking method is to wash out the taste of coffee (water-soluble and water-insoluble organic and inorganic substances) for the second time, and there is no taste.
