Filter paper can be discarded immediately after being used once, which is more sanitary and easy to arrange. The amount of boiling water and injection method can also be adjusted.

2. Flannel filter brewing-maximize the taste of coffee.

The coffee brewed by flannel filtration is the most mellow and delicious. Don't pay special attention to the sorting and storage of the filter, or the coffee will taste very low.

3. Steam pressure coffee machine-Italian flavor

The utility model relates to a steam pressurized coffee machine, which is characterized in that the coffee liquid is instantly pumped out by steam pressure. Strong bitter steam coffee is the basis of all kinds of coffee.

Before making coffee-prepare water to match it.

After fresh water is boiled, it will contain a proper amount of carbon dioxide, which can 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 deteriorate the composition of coffee. Too much or too little is not good.

Heat preservation and preservation of coffee

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.

Filter paper brewing and grinding method: medium to fine

Brewing with filter paper is the easiest and most hygienic way to brew coffee at home, without buying expensive equipment, and there is another advantage that it is easy to adjust the dosage of coffee powder, hot water and injection method.

The kettle for brewing has a thin spout. Hot water can be injected vertically, and the kettle can be filled with hot water for 7-8 minutes. When pouring boiling water, slowly pour the coffee when it is little, and quickly pour the coffee when it is long, so as to brew strong coffee.

Brewing steps:

Alternately bending the sealing line of the special filter paper for coffee, and putting the sealing line into a drip filter 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.

Dropping bubble grinding method of flannel filter screen: medium

Its soaking method is similar to that of filter paper, but the coffee taste is more detailed. The bitter taste and sour taste of coffee can be completely presented, but the inconvenience of flannel filter compared with filter paper lies in maintenance, cleaning and finishing. First of all,

When it is used for the second time, it needs to be washed with hot water, then boiled in boiling water soaked with coffee powder or tea residue for 10 minute to remove the odor of the cloth, then washed with water, washed with hot water after use, and soaked in clear water for refrigeration. Remember not to dry it with soap or directly in the sun, otherwise it will produce odor. When put into the refrigerator, it is best to put it in a closed container to avoid polluting other foods.

Taste.

Brewing step: take out the filter screen from the water, 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 into the coffee, from the center to the periphery, without injecting too much at a time, to prevent the coffee powder from leaking and expanding, resulting in fine foam. When the coffee liquid starts to drip a few drops from the filter screen, take off the filter screen immediately. Sometimes impure substances will be mixed in the foam, and the taste of the extracted coffee will not deteriorate.

Siphon grinding method: medium to fine

This is a method of extracting coffee by steam pressure. It 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 for heating, install a filter on the funnel, pour a proper amount of coffee powder, put the funnel above the flask after boiling (if the water temperature is low, the taste will get worse), evaporate and rise to the funnel after heating, and the coffee powder will float above the boiling water under pressure. Stir and precipitate the coffee powder below with bamboo chips to completely dissolve it, soak it in boiling water for 30 seconds, and then slowly stir it with bamboo chips in the funnel for 6-7 times in a concentric way.

Steam pressure grinding method: extremely fine

Steam pressure coffee brewing is to extract coffee liquid instantly by steam pressure. Espresso stands for fast. Espresso has a strong bitter taste. Fine 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. These bubbles are the unique flavor of espresso.

Brewing steps:

First use the bottom 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 it up and down, and then cover the pot. Remember to lock it to prevent steam or heater from leaking out. 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 top and the foam has not disappeared, pour it into the coffee cup quickly.

Water drop grinding method: fine

Coffee in water is mainly extracted by dissolving coffee in water. Because it takes a long time to extract drop by drop with a coffee distiller, and the taste of coffee varies with the degree of roasting, water quantity and time, it is suitable for deep roasted coffee beans, otherwise the acidity will be too strong.

Brewing steps:

Pour water into the upper pot, fix the filter paper in the cylindrical filter tube, add coffee, and press gently from the top to fix the coffee powder. The filter tube is completely immersed in water, and the cup for containing coffee powder is assembled. It takes about 5-6 hours to extract by adjusting the drip plug (about 40-42 drops per minute).

Grinding method of iced coffee: fine

Brew coffee liquid by any of the above methods, but the concentration should reach 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.

Mixed sugar juice

The preparation 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 will make it difficult to blend coffee. The stirred sugar machine can be stored in the refrigerator for a period of time.
