Do you know how espresso is made?

The invention of instant coffee brought coffee into every household and was another classic milestone in coffee history. Made a historic breakthrough in simplifying the coffee making process. How on earth did such intelligent espresso come about? How is instant coffee made? Let's find out together.

In 1930, the Brazilian Coffee Institute consulted with the Swiss company Nestle and asked them to try to produce a dry coffee that immediately became a beverage after being stirred with heated water. Nestle spent eight years researching. They found that the most effective method was to spray espresso extract through hot air jets. The heat evaporates the water from the coffee extract, leaving behind dried coffee particles. The powder became a popular drink because it dissolved easily in boiling water. The new instant coffee was launched under the name "Nestle," a famous brand that has been known worldwide since then.

Nowadays, the freezing and drying method is also used in the life of instant coffee. The method involves setting the coffee and then evaporating the water. The manufacturing process was invented in 1906, but it was not widely used until recent decades. Manufacturers claim that this method preserves more of the coffee's original flavor.

First, filter paper brewing---the easiest brewing method

The easiest way to make coffee. Filter paper can be used immediately discarded, more sanitary, but also easy to clean up. The amount of boiled water and the method of injection can also be adjusted. One serving can also be brewed, which is the best brewing method for a small number of people.

A dripper has one hole and three holes. Three holes are used here. It is better to pour boiling water into the pot mouth with a small mouth, so that boiling water can be poured vertically on the coffee powder, which is more appropriate.

1. Coffee powder for one person is about 10-12 grams, while boiled water is 120сс. 2. For those who like light coffee, the powder amount is about 8 grams per person. 3. People who like strong bitterness can have 12 grams of powder per person and cook it fully. 4. It is easier to fill a pot with hot water for about seven or eight minutes, and the amount of water to be filled depends on the number of people. 5. Heat the beaker to the point where it doesn't boil before pouring it into the coffee cup. 6. Do not drop the filtered extract to the last drop (if all drops are finished, there may be impurities or impurities).

[Procedure]①. The following part of the filter paper is folded along the suture part and then put into the drip. 2. Pour the ground coffee powder into the drip according to the number of parts (about 10-12G for one person), and then tap a few times to make the surface flat. 3. After boiling the water in a teapot, pour it into a small-mouthed kettle, gently and steadily inject the boiling water from the center point, and slowly make the boiling water penetrate and spread over the coffee powder in a spiral manner. Be sure to pour in slowly. In order to extract the delicious ingredients, steam the coffee powder that has been swollen (stay for about twenty seconds). 5, the second boiling water, slowly injected from the surface of the coffee powder. The amount of water injected must be consistent with the amount of coffee extracted, and the amount of filtered boiled water must be maintained at a certain level. 6. Stop when the extracted liquid reaches the number of parts, and discard it in the state where boiled water remains in the filter paper.

Second, flannel filter brewing----show the maximum limit of coffee flavor

[Features] Coffee brewed with flannel filter is the most fragrant and delicious. Do not filter the finishing and storage to pay special attention, otherwise the coffee taste will be low.

[Preparations before brewing]1. Coffee powder will expand after boiling water injection, so choose a slightly larger filter. 2. The fluffing of the filter screen is done outside, and the water is fully twisted off and the wrinkles are straightened before use.

[Storage of flannel filter] When using a new flannel filter, wash it with a brush to remove residual paste or smell (soap or soap powder is not allowed at this time). Boil used coffee powder in water for five minutes before washing.

[Storage method of flannel filter] Filter cloth should be washed well with water after use, and put in cold storage with water to prevent oxidation. And must change the water every day, otherwise it will cause scale cloth blocking. When in use, brew with warm boiled water, and then fully wrung out before use.

[Procedure]① Inside the cloth, coffee powder 10-12G for one person is put into the filter cloth, and then the coffee powder is flattened.② Shallow roast coffee boiling water temperature is about 95 degrees, and deep roast is lower, initially injected in a thin line, while controlling the amount of boiling water while drawing a circle. After the coffee powder has been finely foamed, it will be stewed for 20 seconds, during which time it must be "paused." After the second time, each time with the same amount of boiling water in a spiral injection, from the center to the outside and back to the center.③ Do not let the boiling water drip completely, inject it according to the number of people, and take it out when the boiling water in the filter cloth is still residual. 4. At the end of extraction, the temperature of the coffee liquid should be heated without boiling it. Shake gently before pouring into a glass.

Third, steam pressure coffee maker---Italian flavor

[Features] Steam pressure coffee maker is characterized by the use of steam pressure to extract coffee liquid instantaneously. Strong bitter steam coffee is the basis of all kinds of coffee, with the increase of years more popular.

With the rapid development of instant coffee, instant coffee is becoming more and more simple. A packet of instant coffee contains sugar, milk and coffee. A latte that requires only hot water to brew and stir to make a cup of coffee.
