Italian concentrate (Espresso) beginners say

When you first learn Italian concentration, there are always a lot of specious problems in front of you:

1. What is espresso (Espresso)?

To put it simply, espresso is coffee extracted by an Italian coffee machine.

Italian coffee machine is one of the many ways of coffee extraction, just like hand pulping and siphon.

The coffee extracted by the espresso machine is rich in flavor, often called "one shot". When the extracted coffee is drunk directly as a drink, it is called espresso (Espresso). Because of its rich flavor, it is a good choice for making fancy coffee.

In the World barista Competition (WBC,World Barista Championship), espresso needs to meet the following conditions:

a. The capacity of an espresso is 1 ounce (ounce) (25-35ml including Krima crema)

b. An espresso is extracted from several grams of coffee (the specific number of grams depends on the coffee and the degree of grinding)

c. The water temperature used for extraction is between 90.5 and 96 degrees Celsius (195 to 205 degrees Fahrenheit).

d. The extraction pressure of the Italian coffee machine is 8.5-9.5 atmospheric pressure.

e. The best time for coffee extraction is between 20 and 30 seconds, but there is no mandatory rule

f. For the Italian concentrate used in the same drink, the difference in extraction time must be controlled within 3.0 seconds.

g. Espresso must be served in a 60-90ml (2-3 oz ounce) coffee cup with one ear.

h. The Italian style is condensed into a coffee spoon, paper towel and water when the referee tastes it.

two。 How to taste espresso?

When drinking as a drink, you might as well follow the general way of tasting coffee:

Look at the color of crema, the uniformity of color, thickness, ductility, etc.

Smell, caramel, nut, chocolate, etc.

Taste, coffee sweet, sour, mellow, aftertaste, etc., especially pay attention to the Italian concentrated "bittersweet" taste

3. What should be paid attention to in the extraction process of espresso? (take the extraction of automatic coffee machine as an example)

a. When the first drop of coffee appeared, when the extract was obtained, the coffee would not drop until a few seconds after pressing the extraction button.

b. The condition, color, thickness, speed, and change of water flow in the process of extraction.

4. What should the perfect espresso taste like?

Some people say that the perfect Italian condensation is a gift from God, and it is extremely rare to have a perfect extract.

Many students often wonder what a perfect Italian concentrate should taste like.

A senior told me that the perfect espresso taste is the most delicious espresso flavor you have ever had in your life.
