[key points of brewing] 1. Coffee powder is about 10-12 grams per person, while boiled water is 120 grams. two。 For those who like light coffee, the amount of powder is about 8 grams per person. 3. For those who like bitter taste, the amount of powder can be 12 grams per person and fully boiled. 4. The kettle for hot water injection is easier to operate if it is injected for about seven or eight minutes, and the amount of boiling water is prepared according to the number of people. 5. Heat the beaker without boiling it and pour it into the coffee cup. 6. Do not drop the filtered extract to the last drop (if all the drops are finished, there may be miscellaneous smells or impurities, etc.).

[program] the following parts of ① and filter paper are folded along the seam and put into the drip. ②, spoon the ground coffee powder according to the number of people (about 10-12g per person) into the drip, and tap a few more times to make the surface flat. ③, boil the water in a teapot, pour it into a small-nozzle kettle, gently pour the boiled water into the center, slowly screw the boiled water and spread it all over the coffee powder. Be sure to pour it in slowly. ④, in order to extract the delicious ingredients, steam the inflated coffee powder (stay for about 20 seconds). ⑤, the second boiled water, is slowly injected from the surface of the coffee powder. The amount of water injected must be consistent with the amount of coffee liquid extracted, and the amount of boiling water filtered must be kept at a certain level. ⑥, the extract can be stopped when it reaches the number of parts, and the state of boiling water left in the filter paper will be discarded.

Second, flannel filter brewing-showing the maximum flavor of coffee

[characteristics] the coffee brewed with flannel filter is the most mellow and delicious. However, special attention should be paid to the arrangement and storage of the filter, otherwise the coffee will taste low.

[preparation before brewing] 1. Coffee powder expands after boiling water is injected, so choose a slightly larger strainer. two。 Make the outside of the filter, fully twist the water off the wrinkles and straighten it out.

[about the safekeeping of flannel filter] when using a new flange filter, in order to remove the water paste or smell from the cloth, you can wash it with a brush (do not use soap or soap powder at this time. After that, boil the used coffee powder with water for five minutes before washing it with water.

[preservation method of flannel filter] the filter cloth should be washed well with water after use, and water should be added to the freezer to prevent oxidation. And the water must be changed every day, otherwise the scale will cause clogging of the cloth. When in use, brew it with warm water, then fully wring it out and then use it.

[program] ① cloth as the inside, coffee powder 10-12g per person into the filter cloth, and then flatten the coffee powder. ② shallow roasted coffee boiled water temperature is about 95 degrees, while deep roasting is lower, the initial thin line injection, while controlling the amount of boiling water while making a round injection. The coffee powder should be steamed for 20 seconds after brewing, which must be "suspended" during this period. After the second time, each time the same amount of boiled water is injected in a swirl, from the center to the outside and back to the center. ③ do not let the boiled water drop completely, just inject it according to the number of people, and take it out when the boiling water in the filter cloth is still in the remaining state. At the end of ④ extraction, the coffee liquid should be heated instead of boiling when the temperature decreases. Shake gently and pour into the cup.

Steam pressurized coffee maker-Italian flavor

[feature] the steam pressurized coffee maker is characterized by the use of steam pressure to extract the coffee liquid instantly. Bitter steam coffee is the basis of all kinds of coffee, and it becomes more popular with the years.

[about utensils] Vertical table (for household use) and automatic (mainly for business use), the use of upright table is introduced here.

Preparation before brewing. In order to improve the extraction effect, the coffee powder put in the bucket is pressed hard. The steam in the upper part of the kettle should not be leaked, but should be well covered. two。 Use with the number of people. It is necessary to use a capacity appliance that is larger than the number of people. if the vapor pressure is weak, the coffee drawn will be less delicious.

[program] 1. Pour the required amount of boiled water into the lower half of the bag, then gently squeeze the deep-baked and finely ground bucket, about 6-8 grams per person, from the top. two。 The upper half of the pot and bucket are combined with the lower part of the pot. Especially in the upper half of the pot must be well fastened. 3. Add fire to the set of utensils. When the boiled water in the lower half of the kettle boils, the water column will rise and take it off the fire after bearing the air. The coffee liquid sprayed up from the powder layer through hot water in the upper half of the kettle will be extracted. 4. The utensils are very hot, so be careful not to get scalded, and then inject them into a cup that is kept warm in advance.
