What is espresso?

Espresso, which is called "Espresso" in English, is an espresso that is extracted by a pressurized coffee machine for about one ounce. It's very popular in Italy. Espresso sounds similar to the English word Express, while Espresso also has fast and rapid properties. It takes only 30 seconds to extract a cup of espresso, while in Italy, guests will lean against the bar and order a cup of espresso. When the barista hands it to the guest, the guest will finish the coffee in one or two mouthfuls, pay for it and leave for less than two minutes.

What is the oil (Crema) in espresso? When the coffee machine extracts espresso, the coffee is ground to a very fine size and extracted under pressure up to 9bar. When the hot water passes through the coffee pressed powder, the carbon dioxide in the coffee powder is under too much pressure, and the water is supersaturated for the carbon dioxide. There is no way to release the carbon dioxide and melt directly into the coffee liquid. The high pressure also forces the oil in the coffee to detach from the coffee pressed powder and is brought out by the hot water.

After the coffee is extracted, when the coffee liquid flows out of the coffee machine, the atmospheric pressure returns to normal, and the carbon dioxide that remains in the coffee liquid. When it was ready to return to the air, the carbon dioxide encountered the oil in the coffee liquid. The grease wraps the carbon dioxide that is ready to return to the air. This golden layer of Crema grease is the soul of espresso.

How to make espresso?

Step 1: clean the powder bowl

Before extracting espresso, you need to remove the coffee handle and clean the coffee powder bowl with a special rag to ensure that the powder bowl is clean and free of water stains. Step 2, grind the coffee powder and pick up the switch to turn on the bean grinder and start grinding the coffee beans. Before picking up the coffee powder, you need to put the handle on the electronic scale and clear the zero, and then put on the electronic scale after receiving the coffee powder to make sure that the weight of the coffee powder is the same each time. When picking up the coffee powder, pay attention to the position of the coffee powder on the handle and make sure that the coffee powder falls evenly on all areas of the handle.

Step 3. Cloth powder

After receiving the coffee powder, spread the coffee powder with your finger or dispenser, in order to ensure that the coffee powder is evenly distributed and avoid inconsistent density when filling and pressing later.

Step 4: filling and pressing

After the cloth powder is filled and pressed, the direction of the filling pressure should be vertical to the powder bowl, and the strength should be moderate, neither too light nor too heavy, too light will make the coffee pressed powder loose, too heavy will make the coffee pressed powder too tight and dense, and the water will be difficult to pass through the coffee pressed powder, resulting in overextraction.

Step 5. Buckle the handle and extract espresso at the same time.

Gently buckle the handle on the coffee machine to avoid knocking the handle against the coffee machine. extra bumps will cause cracks in the coffee pressed powder on the handle, resulting in channel effect, insufficient and uneven extraction. As soon as you buckle the handle, turn on the extraction switch and begin to extract espresso. At the beginning of extraction, the liquid weight of espresso was weighed by electronic scale, and the time of coffee extraction and the color state of coffee liquid were paid close attention to.

Qianjie espresso extraction parameters reference: 20 grams of coffee powder extract 40 grams of coffee liquid, time is 25-30 seconds

Step 6: finish the extraction and clean the powder bowl

Remove the pressed powder from the powder box, clean it with a special rag, and finally buckle the handle back to the coffee machine.

Flavor characteristics of espresso

Aroma

When discussing food, pay attention to a "color and smell", that is, the first impression of selling appearance is very important, and the first impression of aroma is a "ticket" to determine whether you want to try it or not. The aroma of coffee is also an important impression that attracts people to drink coffee. The aroma range of espresso is relatively small, and it is generally necessary to lean over the nose. Traditional espresso has a strong creamy, nutty aroma that makes you imagine an almond cream cake. If you choose a slightly lighter baked SOE, the aroma is more light and permeated, emitting an attractive aroma of flowers and fruits.

Taste

This is the most attractive thing about espresso. The Crema of espresso is the soul of the whole espresso and makes it taste mellow. Therefore, when tasting espresso, unlike hand-made coffee drinks, you need to drink heavily, allowing espresso and oil to wrap around the tongue and mouth and enjoy silky. Traditional espresso tastes like cream and honey. SOE, on the other hand, tastes relatively thin.

The taste of traditional espresso is generally bitter, which is unacceptable to many people. If the front street is used to describe the flavor of espresso, it can be described as "turning the corner but there is another village". Even if we describe it as nut, dark chocolate and caramel when drinking concentrate, which translates as "colorful bitterness", as the coffee liquid is swallowed, the coffee left in the mouth will return a lasting sweetness and aroma. This is the aftertaste, and it is also an important category of espresso.

Of course, the flavor performance of espresso is closely related to the coffee beans used. For example, Qianjie currently uses its own sunflower warm Italian coffee beans, and the espresso flavor produced is vanilla cream, sherry, caramel and chocolate.
