The History of Italian espresso-the meaning of Italian espresso

History of Italian espresso-Italian espresso meaning

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.

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 coffee beans to lose many irritating components, and short water, it is impossible to make all the caffeine in coffee dissolve in water, so Espresso can be said to be more harmless than ordinary coffee.
