The false impression of espresso = high caffeine seems to have taken root in everyone's mind. In fact, the real espresso beans are usually roasted deeply for a long time, and there is not much caffeine left. As for the remaining little caffeine, it must be extracted for a long time before it can be dissolved.
Espresso has a thicker texture than water drop coffee and contains more dissolved matter per unit volume than water drop coffee; supply is usually calculated in terms of "shot". Espresso is chemically complex and changeable, many of which decompose due to oxidation or a drop in temperature. A feature of properly brewed espresso is the presence of coffee fat (crema), a reddish-brown foam that floats on the surface of espresso. It consists of vegetable oils, proteins and sugars. Coffee fat has the combination of emulsion and foam colloid. Through the short-time and high-pressure brewing process, the unique flavor of a cup of coffee is stronger than other brewing equipment after being concentrated. However, there is less caffeine because of the short quenching time.

The level is equivalent to the essence in spirits and perfumes, which is more choking, and not everyone can accept it. Drinking this kind of coffee will spoil people.

There are more extreme people who like to add wine to their Double, such as rum or whiskey, to pursue the satisfaction of being completely surrounded by taste. How to drink: don't try double espresso easily, because you will have the feeling that you can't go up and down. But once you fall in love with it, you can't help it.
