The production of espresso, is Italian American concentrated

I am a coffee practitioner, the following is my personal understanding of coffee, I will summarize my experience of coffee for your reference, do not spray if you have different opinions! Today is the most basic coffee of espresso: espresso

Espresso, in the eyes of Italians is a part of life, in the morning is a cup of short coffee, a cup of long coffee at noon, and then cappuccino, latte, etc., coffee is more and more in our Chinese life, how do we drink this cup of coffee, teach to make a good cup of coffee.

The first thing to know is what espresso is, what does it need, and what are the standards?

Need: coffee machine (professional semi-automatic coffee machine), coffee beans (high freshness), grinder, milk, chocolate sauce, whipping cream, sugar packets and other coffee accessories (this is too much, there is no way to say too much detail, friends who want to open a store can refer to it).

Standard: 7g-10g ground coffee 8-10bar pressure Boiling water at a temperature of 87-93 degrees Make a 30ml espresso cup in 22-30 seconds.

Influencing factors: 1. The quality of the coffee machine, the effect of professional semi-automatic machines is definitely better than that of small semi-automatic machines for general households, except for high-end people (especially high-end household machines).

2. Grinder, the thickness uniformity of the coffee powder ground by a good grinder is relatively high, and each coffee powder can be fully extracted.

3 personnel (main part).

4. Water quality, environment, etc.

The main explanation is the personnel factor.

In the case of the same equipment and water source, the personnel operation is prominently important, mainly three variables will affect the quality of a cup of coffee, the thickness of the coffee powder, the amount of coffee powder, and the strength of the pressed coffee powder.

The coffee powder is too coarse, the coffee powder is too little, the pressure is too light, the density of the coffee powder is too low, the contact time between the extracted boiling water and the coffee powder is too short, the extraction is not sufficient, the color is light, the coffee oil is white, the coffee taste is basically absent, the coffee flow rate is fast, and vice versa.

Observe the flow rate of the coffee when extracting the coffee, and know how to adjust it if it is too fast or too slow, so that the extraction is sufficient (I personally think that the tail of the little mouse is just right).

A good cup of espresso grease is dark golden yellow, very heavy, the cup is tilted at 45 degrees, the grease layer will not reveal the black coffee liquid, the coffee is relatively heavy, and the faint aftertaste of coffee will remain in the mouth within ten minutes.

Ingredients: coffee powder, purified water;

Steps: 1. Take 7 grams of coffee powder and pour it into the filter of the distilled coffee machine;

2. Knock the coffee filter cover flat to evenly distribute the coffee powder, and press the coffee powder in the filter cover with a pressure stick;

3. Install the coffee maker, put in the purified water according to the instructions of the machine, start the switch, take out 30ml of espresso, and drink it hot.

The espresso is used as a coffee base to make a variety of flavored coffees; Americano, on the other hand, is the right ratio of espresso made with water.

Do you know how the often drunk concentrated and American style came from?

Originating in Italy, the sedan royal coffee is named in Italy in the way of "fast". In Chinese it means espresso coffee.

During the war, American soldiers stationed in Italy were not accustomed to espresso, and added water to the concentrate to dilute it to simulate the taste of home. Hence the name Americano.

Based on espresso, it can be divided into two categories: 1. Black coffee; 2. Milk coffee.

Extract the coffee powder at high temperature, high air pressure, and in a short period of time, you can get a cup of espresso

A good concentrate can drink the sour, bitter, and mellow layered flavor.

There are three types of coffee that require espresso to make with mocha, latte, and hot American

1 Hot American: Pour a certain proportion of hot water into the cup to concentrate.

2 Latte: Extract espresso whipped milk foam latte art.

3 Mocha: Pour the chocolate sauce into the cup to concentrate, stir well, beat the milk foam, latte art, and chocolate sauce carving.

The extracted espresso can be double-served or single-serving, and the double espresso has a strong flavor; A single serving is more suitable for friends who are caffeine intolerant and can't drink strong coffee.

Ingredients: coffee beans, water, coffee machine, grinder, electronic scale.
