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 burnt bitter water, 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. \ x0d \ x0d \ Points to pay attention to when making coffee at home: \x0d\ 1. The degree of coffee grinding depends on the coffee equipment you choose. Because different coffee making methods need different grinding thickness. Use 92-96 degrees of water. \x0d\3. Different cooking methods require different cooking time \ x0d \ x0d \ Use a small home coffee machine-coffee must pass through a filter paper or a gold filter \ x0d \ 1. Use of small funnel: put a filter paper in the funnel and a cup of coffee powder (8- 10) in the filter paper bag. (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. \x0d\\x0d\2。 Electric drip 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 the pipes of boiler and brewing system; 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. \x0d\ coffee powder thickness: through filter paper or pot filter: medium \ x0d \ x0d \ coffee machine (also called tea maker or pot press) French coffee press \ x0d \ This is a traditional soaking method, and coffee powder and brewed coffee liquid are in the same container. This method can taste the advantages and disadvantages of coffee. \x0d\\x0d\ Practice: Press the coffee powder to match the thickness of the kettle (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. \x0d\\x0d\ Avoidance question: \x0d\\x0d\ 1. Choice of coffee pot: According to the current coffee culture atmosphere is slowly developing, the market for coffee brewing equipment is not very sound. When buying, be sure to pay attention to the uniform glass thickness of the coffee pot, the vertical cups and barrels with the same caliber, and the metal shelf outside should be strong and have a certain hardness. \x0d\\x0d\ Second, water temperature: too high water temperature will make the oil quality of coffee worse and make coffee bitter, while too low water temperature will not make coffee sour and astringent. So the normal water temperature is 9 1-96 degrees Celsius. \x0d\\x0d\ III. Grinding thickness of coffee powder: This is a soaking cooking method, which takes 3 minutes to soak, so the coffee powder should be thick. \x0d\\x0d\ Fourth, press down: You need to do this carefully, hold down the pressure bar with your palm, and press 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. \x0d\ Coffee powder thickness: thick. \x0d\ x0d \ Italian mocha home espresso (also called "espresso on the stove") Mocha espresso \ x0d \ basically, coffee is added to the top of the bittern cup, but it should be gently pressed. There should be a certain gap at the top of the halogen cup, because coffee will expand after soaking in water. Cook over medium heat until you hear the sound of water in the pot. Remove the pot and serve coffee at the same time. \ x0d \ x0d \ Coffee powder thickness: Italian home espresso: medium to high. \ x0d \ x0d \ espresso, machine-made espresso \ x0d \ salt water cup, add 7g coffee and press it gently, leaving a certain gap at the top, because the coffee will expand after soaking in water. Add water and observe the color of Crema when she comes out of the coffee pot. When the coffee oil starts to turn from golden brown to white, stop adding water. The whole process takes 22 to 28 seconds. Remember, a real espresso is a very small cup of coffee (40 to 50 ml or 1.5 oz). After five seconds, the coffee should start to flow out. It should flow at the bottom of the coffee spoon like hot honey. If it takes too long to start flowing, try not to press the coffee too hard, or use coarser particles instead. If the coffee flows out too fast, press it a little, or use finer particles. \ x0d \ x0d \ coffee powder thickness: espresso: fine. \ x0d \ x0d \ cappuccino \ x0d \ espresso comes from espresso. Espresso will taste good when it is made. If the espresso is not standard, it will also be affected. The brewed foamed coffee is divided into three steps. \x0d\ Step 1 Prepare espresso according to the above method. Espresso should account for one-third of this drink (not one-third of the cup, because the capacity of the cup is unreasonable). \x0d\ Step 2: Add one third of the hot milk (the same amount as espresso). \x0d\ Step 3, add another third of the foam. \x0d\\x0d\ Thickness of coffee powder: directly use the prepared fragrant coffee without adding powder. \ x0d \ x0d \ Turkish coffee is probably the most difficult coffee to brew. Real Turkish coffee can only be obtained through complicated procedures. Each cup of coffee needs two spoonfuls of coffee and one spoonful of sugar (if necessary). You should drink Turkish coffee in a small cup. Add coffee and sugar to Turkish coffee pot "Ibrik" (Jezva). Your boy measures water and adds as many cups as you need. The coffee pot can only be half full, because a lot of foam will be produced when the water is about to boil. After the coffee boils, remove the coffee pot from the fire and let the foam disappear. Repeat the above procedure twice, and then slowly add coffee to the small cup. If you do it carefully, most of the coffee particles should stay in the coffee pot. A real Turkish coffee expert can add a little foam to each guest's cup, but this can also be done with a spoon. \ x0d \ x0d \ Did you know that two-thirds of coffee drinkers drink Turkish coffee (or Greek coffee, depending on where you come from)? \ x0d \ x0d \ coffee powder thickness: superfine. \ x0d \ x0d \ Legend has it that one day when Muhammad was about to be conquered by his sleepy head, his archangel Gabriel immediately offered him a cup of brewed coffee. The rich aroma of coffee greatly inspired Muhammad, making him-subduing forty warriors and making forty women happy-but this story did not explain how Gabriel made this magical drink. \x0d\\x0d\ Method of making coffee: Coffee brewing methods are generally divided into the following types -\ x0d \ x0d \ Turkish lbrik coffee: \ x0d \ \ x0d \ This is a concentrated, high-concentration coffee with a little aroma. How to make it-heat a copper coffee pot, put a proper amount (one teaspoon per cup) of finely ground coffee powder and sugar in the pot, and brew with boiling water. The total contact time is about 1 min and the pressure is 1 atm. \x0d\ There are two ways to drink this coffee: \x0d\ 1. Start drinking when the insoluble part is still suspended on the surface. \x0d\2。 Wait until it settles before drinking. \ x0d \ x0d \ Filter coffee: \ x0d \1.5 ounces of lightly roasted and coarsely ground coffee powder is put into the filter paper, and then boiled water is slowly poured into the center and periphery of the coffee, and then returned to the center from the periphery. Drop the cooked ground coffee powder into the pot, about 8 ~ 8 water per cup. The boiling water temperature is 100℃. \x0d\\x0d\ mocha: \ x0d \ \ x0d \ is a kind of distillation. Coffee brewed in a mocha pot has stable concentration and aroma. Mocha pot is divided into upper and lower parts. Water boils in the lower part of the pot until it boils. When water boils, it rises through a filter filled with coffee powder and reaches the upper part of the pot under the pressure of steam. When the coffee begins to flow to the top of the pot, turn down the fire, because too high a temperature will make the coffee have a burnt taste and destroy the original flavor. The common choking method of Japanese cuisine also uses the same principle. \ x0d \ x0d \ Napoletana: \ x0d \ x0d \ is a kind of filtered coffee. Put the moderately ground coffee powder (5-6g per cup) into the filter of Napoleon's pot, cover the filter and put it into the boiler. When the water boils, remove the pot and turn it upside down. Napoletana coffee is not very strong, but it tastes full and smooth. \ x0d \ x0d \ espresso machine brewing: \ x0d \ x0d \ coffee is an extremely unstable liquid, which may change its characteristics at once. This is one of the reasons why the coffee machine was invented. An espresso machine can extract several cups of coffee continuously. The high pressure in the brewing process can emulsify and dissolve the oil and gum in coffee beans, and the essence of beans can be completely extracted by pressure, so that the brewed coffee is more concentrated and has better taste and fragrance. \ x0d \ x0d \ siphon: \x0d\\x0d\ First, put the coffee powder into the upper funnel, then add the water into the kettle, then fit the funnel mouth tightly to the kettle mouth and boil the water. When the boiling water rises to the funnel, soak it for about 40 seconds to 1 minute while stirring, and then turn off the alcohol lamp. At this time, when the coffee drips back into the pot, you can take down the funnel and pour it out for drinking. \x0d\ Coffee lovers know that choosing good coffee is only the first step to make good coffee, and proper storage, grinding and brewing can ensure the quality of coffee. \ x0d \ x0d \ Pay attention to the following points when brewing coffee -\ x0d \ x0d \ Boiling will make coffee bitter, so never brew coffee, and the appropriate brewing degree should be slightly lower than 96℃. \x0d\ Coffee can't be heated any more. When brewing, you should pay attention to cooking only the required amount at a time, and it is best to drink it as soon as it is cooked. The best drinking temperature of coffee is 85℃. \x0d\ A cup of coffee contains 98% water, so it is best to make coffee with filtered water, especially chlorine-containing water. \x0d\ Don't reuse coffee grounds, the brewed coffee grounds will only leave unpleasant bitterness. \x0d\ Carry out proper coffee grinding according to the coffee machine used. Grinding too fine will make coffee bitter, and it is easier to block the coffee machine. Too rough grinding will make coffee tasteless. For filtration brewing, the time for dropping properly ground coffee powder should be 2-4 minutes \x0d\ recommended dosage -2 tablespoons coffee powder /6 ounces of water.
