How to make coffee is better?
Before making coffee-be sure to have good water and fresh water. After boiling, it will contain a proper amount of carbon dioxide, which will increase the aroma of coffee, but the continuous boiling of water will reduce the evaporation of carbon dioxide, so the optimal water temperature is 95℃. Too low water temperature will not completely release the taste of coffee, while too high water temperature will make the coffee ingredients deteriorate. Too much or too little is not good. In order to keep the temperature of coffee, you can heat the cups and plates with coffee first. If you drink coffee, you can soak the coffee pot in hot water for insulation. If you put the coffee pot directly on the gas stove, be careful not to boil it. Once the coffee is boiled, some components will undergo chemical changes, the acidity will become stronger, and the original flavor will be destroyed. Coffee brewing method 1. The simplest brewing method with filter paper grinding method: Fine brewing with filter paper is the simplest and most hygienic brewing method. You can brew coffee in the simplest way at home without buying expensive equipment. Another advantage is that it is easy to adjust the amount of coffee powder, the amount of hot water and the injection method. The brewing pot has a thin spout. Hot water can be injected vertically, and the pot can be filled with hot water for 7-8 minutes. When pouring boiling water, pour slowly when the coffee is small, and pour quickly when the coffee is large, so as to brew strong coffee. Brewing step: alternately bending the sealing line of special filter paper for coffee, and putting it into a drip coffee pot; Put 10g coffee powder into a cup of coffee, and gently shake the drip coffee pot to flatten the coffee surface; Carefully pour boiling water on every inch of coffee powder; In order to extract the delicious ingredients of coffee, it takes about 20 seconds to cook; According to the amount of coffee, pour a proper amount of hot water from the center outward, and draw a circle at a time until the coffee drops into the tray. 2. Flannel filter drip grinding method Ultimate manual drip grinding method: Its soaking method is similar to that of filter paper, but the coffee tastes more detailed, which can completely present the bitterness and sourness of coffee, but the flannel filter is inconvenient to maintain and cleaner than filter paper. When you use it for the first time, you need to rinse it with hot water. Then put it in boiling water soaked with coffee powder or tea residue 10 minute, remove the peculiar smell of the cloth, wash it with water, wash it with hot water after use, soak it in clear water and refrigerate it. Remember not to use soap or dry it directly, otherwise it will produce odor. When it is put in the refrigerator, it is best to put it in a closed container to avoid polluting the smell of other foods. Brewing step: take out the filter screen from the water and gently wring out the water by hand. Pour the coffee powder into the filter screen, with the plush facing outward, gently shake it, and put the boiling water drops into the coffee, from the center to the periphery. Don't inject too much at a time to prevent coffee powder from leaking out and expanding, resulting in fine foam. When the coffee liquid starts to drip a few drops from the filter screen, remove the filter screen immediately. Sometimes impure substances are mixed in the foam, and the taste of coffee will become worse. After extraction, the central part will not sink, and no foam will remain on the surface. 3. Siphon appreciation of drama performance grinding method: Medium-fine is a method of extracting coffee by steam pressure, which is interesting because it can completely see through the process of coffee extraction. After boiling, the boiling water in the flask directly evaporates and rises to the funnel to complete the coffee extraction procedure, and the extracted coffee flows into the flask again. This seems to be a theatrical performance, which not only enjoys the taste, but also satisfies the vision. Brewing steps: pour water into the flask, light the alcohol lamp below and heat it, put the filter on the funnel, pour a proper amount of coffee powder into boiling water, and insert the funnel above the flask (if the water temperature is low, the taste will become worse). After heating, water evaporates and rises to the funnel. Coffee powder will float above the boiling water under pressure, and the coffee powder deposited below will be completely dissolved, soaked in boiling water for 30 seconds, and then slowly stirred with bamboo slices in a funnel for 6-7 times. After stirring for 45 seconds, the alcohol lamp will be turned off, and the coffee in the funnel will flow down to the flask after being filtered by the filter, and you are done. 4. The steam pressure espresso grinding method is like riding a fast train: very fine steam pressure coffee uses steam pressure to extract coffee liquid instantly, which means fast. Espresso espresso has a strong bitter taste, and delicate and soft bubbles will appear on the surface of freshly brewed coffee, because hot water is ejected instantly and coffee is extracted at one breath, which is the unique flavor of espresso. Brewing step: first use the lower part of the pot and pour the water in the pot for nine minutes (because the water will be absorbed by the coffee powder). Pour the coffee powder into the cup, gently press it with a spoon, cover the pot up and down, and then cover it. Remember to lock it to prevent steam or heater from leaking. Put the coffee pot on the gas stove, boil it over high heat until the hot water rises, and turn it down. Remember not to open the lid to prevent water from overflowing. When the hot water rises to the upper part and the foam has not disappeared, pour it into the coffee cup quickly. 5. The water-drop method is an exquisite carving method that requires patience. Grinding method: The fine method is to dissolve coffee in water and slowly extract it from the water. Because it takes a long time to extract drop by drop with a coffee distiller, the taste of coffee will vary with the degree of roasting, the amount of water and the time, so it is suitable for deep roasted coffee beans. Otherwise the sour taste will be too strong. Brewing step: pour water into the upper pot to fix the filter paper in the cylindrical filter tube, add coffee, and press gently from the top to fix it. Assemble the filter tube and the cup with coffee powder, and adjust the drip plug (about 40-42 drops per minute) for about 5-6 hours to complete the refining. 6. Grinding method of cooling iced coffee by heart and spleen: brew coffee liquid by any of the above methods. However, the concentration should be twice that of hot coffee. Fill the cup with ice cubes and add coffee to make it freeze quickly. Or put the coffee pot in cold water to cool, and then put it in the refrigerator for refrigeration. However, it should be noted that if the cooling time is too long, ice cubes will be formed or the taste will be poor. The mixing method of sugar juice is to boil sugar and water at a ratio of 4:6 and let it cool naturally. It should be noted that too much water will weaken the taste of coffee, and too little water is not easy to dissolve with coffee. After mixing, the sugar machine can be stored in the refrigerator for a period of time.
