Thành Phần Chính Của Tách Espresso

Let's start with the basics: espresso is a drink made by compressing a small amount of water at a near evaporation temperature and passing it through finely ground coffee. Under the pressure of water, all the ingredients of coffee are separated by the phenomenon of penetrating hot water through compressed fine coffee. Water carries dissolved substances, oils, and even insoluble substances into the cup.

There are two basic layers of the espresso cup: the crema layer and the liquid layer.

The crema layer is made up of CO2 foam surrounded by water and oil. Crema also includes coffee and emulsified oils found in coffee beans. This layer can be very bitter and there is a heated debate about whether to stir well before drinking to mix the layers.

The main constituent of an espresso cup is the liquid layer made up of solutes, gases, and insoluble substances. This is the part that makes up the flavor of our favorite espresso.
