Introduction to Italian espresso

Italian espresso is what people often call Espresso. Espresso is an Italian favorite and can be counted as the starting point for any delicious fancy coffee. They are willing to have a hot Espresso at any time of the day. Adults also add a dash of Italian grappa to the glass to make Caffe Corretto. Today, espresso coffee has become a favorite all over the world, and it is also the basic ingredient for making fancy coffee such as cappuccino.

The origin of Italian espresso

In the 1930s, an Italian named Gorggia invented a machine for brewing espresso coffee. He also invented this unique method of brewing coffee, which allows hot water to pass through coffee powder under great pressure. Due to the use of the name "espresso," espresso coffee is often thought of as caffeine-rich coffee, leading to concerns that it is harmful to the body. But in fact, because the longer roasting process has caused the coffee beans to lose many irritating components, and the short water, it is impossible to make all the caffeine in the coffee dissolved in the water, so Espresso can be said to be more harmless than ordinary coffee.

Characteristics of Italian espresso coffee

The most important sign of a good espresso is that it has a light camel-colored Crema on the surface, which is a mixture of fat, water and air in the coffee during the extraction process. The emulsion should be uniform in color and about 3 cm to 5 cm thick. Shake the coffee cup gently. This emulsion will stick to the wall like thick syrup. If the emulsion is dark brown or even black, it indicates that the coffee has been extracted too much; if it is light yellow, it indicates that the coffee has not been fully extracted.
