Walking into a cafe, many people will choose a fancy coffee based on Italian concentrate, such as latte, cappuccino, American coffee and so on. Each coffee has its own unique flavor, such as the perfect blend of latte coffee milk, the thick milk foam of cappuccino, and the light softness of Australian white coffee, are very popular. In this article, Qianjie Coffee will share with you the knowledge of making espresso.

To make a cup of strong and delicious fancy coffee, you need to prepare two kinds of ingredients, namely espresso and whisked milk, and then the two ingredients are mixed in different proportions and in order to get fancy coffee with different flavors. Like everyone's favorite latte and cappuccino, but there is less milk foam on the surface of the latte.

Milk plays a very important role in a cup of coffee. Good milk texture can enhance the flavor characteristics of coffee. Coupled with beaten milk foam, silky and sweet milk can be made. Like front street coffee, you usually choose whole milk because it contains fat and protein that not only enhance the flavor, but also make the foam more stable.

There is also the problem of keeping milk fresh. If the milk is kept for a few days and it is not so fresh, the protein will break down into amino acids. Refrigerating the milk in the refrigerator can slow the process, but if it is not put back in time after it is taken out, it will speed up the denaturation of the milk, even if it still tastes or smells fresh. So Qianjie advises you to put the milk in the refrigerator after you use it.

When everyone chooses a type of milk, it is about the steps to dispose of the milk. There are two steps to get rid of milk, to get rid of it and to get rid of it. Next, Qianjie Coffee introduces the following process of dispensing milk.

1 pour the milk into the milk tank, the liquid level should be below the outlet of the milk tank at 1 beat 3 to 2 beat 3.

(2) clean the steam pipe and remove the residual material.

3 put the milk tank close to the steam pipe so that the steam pipe just goes into the liquid surface, and the point deviates slightly from the center of the liquid level. Open the steam valve and listen to the hiss of the steam operation.

After getting enough fine milk bubbles, slowly remove the milk jar. This step is to get rid of, at this time the temperature of the milk can not exceed the body temperature! Heat the milk to about 60 degrees, but not more than 70 degrees, otherwise the protein structure in the milk will be destroyed.

(5) prepare to have sex. Take the outlet of the milk tank as the fulcrum, lift the milk tank up, let the steam pipe go deep into the milk, and the milk should have a vortex under the action of steam.

6 by the time the milk tank starts to burn, the temperature should reach 60-65 ℃ (the test is to touch the bottom of the tank with your hand, at this temperature, you should not last 3 seconds). It's done.

Don't close the steam valve yet, use the steam to clean the steam pipe.

8 knock on the side of the milk tank, shatter the large foam on the liquid surface, shake the milk tank, and mix the liquid and milk foam. A good milk foam will be a success.

After talking about milk, there is the question of espresso. The first is to choose beans. It is important to choose a coffee bean that suits your own flavor. Like Qianjie Coffee, the Italian mix beans currently used are sunflower warm sun coffee beans. This blend uses red cherry coffee from Honduras and Esseyega Chevy. Through the continuous blending of baristas on the front street, the perfect ratio is 6:4. The espresso is made with obvious acidity, berry aroma and wine aroma, and a pleasant finish.

This espresso bean is baked by Qianjie Coffee. In addition to this coffee bean, there are three other coffee beans with different Italian flavors. Such as Qianjie Coffee basic blending of coffee beans: the use of coffee beans is Yunnan coffee beans with Brazilian beans, according to the proportion of 3:7, the production of Italian coffee with soft fruit acid, caramel sweetness, nut, dark chocolate flavor, smooth and sticky, but light taste.

And Qianjie boutique coffee blending: using Colombia: Brazil, through the Qianjie baristas 3:7 proportion blending, the production of Italian coffee soft slightly sour, sweet, nuts back sweet, the overall feeling is not too exciting, peaceful, fat belongs to medium.

When you have selected the beans, you can extract the coffee beans. The following are the parameters of Qianjie Coffee for extracting sunflower warm sun coffee beans:

Grinder: Pegasus 900N

Degree of grinding: 1.6

Pressure: 9 bar ±2

Temperature: 90.5 ~ 96 °C

Time: 20: 30 sec

Powder content: 20g (double espresso)

Extraction amount: 40ml

Ideally, the coffee liquid from the outlet is very uniform in terms of color and thickness. If the beans are grinding too fine or pressing the powder too hard, it will prolong the time for the water to pass through the powder, resulting in excessive extraction (bitterness); if the bean is ground too thickly or the powder is not pressed enough, it will shorten the time for the water to pass through the powder, resulting in insufficient extraction (watery, thin taste).

If the extraction is successful, the espresso flavor of Qianjie Coffee: smooth taste, medium mellow thickness, obvious acidity in the mouth accompanied by a hint of berry aroma, whisky, strong chocolate flavor.
