Introduction to the method of grinding degree of varieties describing the taste characteristics of Italian-style coffee

Espresso

It usually takes 7 grams of coffee powder and 40 to 65 milliliters of water to make a small cup of espresso. If you want the coffee to be stronger, you can reduce the amount of water. Boiled Espresso should be placed in a thick, small coffee cup that is pre-heated, and it will not taste until it is hot.

The coffee beans that make espresso are usually Arabica beans. It doesn't matter whether you use individual beans to brew Espresso. There is a lot of freedom to choose. Some coffee merchants even sell coffee beans used to make espresso that are a mixture of several Arabica beans.

The coffee powder for making espresso should not be ground too fine, which will cause the coffee to be over-extracted and make the coffee taste bitter. On the contrary, the coffee will not be ground too thick, so the extracted coffee will taste too light.

The most important sign of a good espresso is that it has a light camel-colored emulsion (Crema), which is a mixture of fat, water and air in the coffee during the extraction process. The emulsion should be uniform in color, about 0.3 cm to 0.5 cm thick, shake the coffee cup gently, and this layer of emulsion will stick to the wall like thick syrup. If the emulsion is dark brown or even black, the coffee is overextracted; if it is yellowish, the coffee has not been fully extracted

Italian coffee ESPRESSO

"Espresso" means "express" or "fast" in Italian. Italian coffee is called the root of good coffee. Although the reputation of Italian coffee belongs to Italy, the first Italian coffee machine was simply tried in France, but as we know today, it was successfully developed by the Italians.

In Italy, the price of a cup of Italian coffee is controlled by the government. For Italians who want to experience the taste of extra-bitter, espresso, they use "demitasse" (which means half a cup) to enjoy this coffee, which consists of 1.5 ounces of black coffee with some excellent cream to float on top of the coffee.

Generally brewing Italian coffee at home is made using a mocha pot invented in Italy, which also uses the principle of vapor pressure to quench coffee (another Watt's apprentice). The mocha pot can make the pressurized vapor pass directly through the coffee powder, allowing the steam to pass through the cell wall of the coffee powder (or Hook's apprentice), quenching out the inner essence of the coffee, so the brewed coffee has a strong aroma and strong bitter taste, and a thin layer of coffee oil appears on the surface of the coffee, which is the source of the attractive aroma of Italian coffee.
