Deeply explore 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 running it through a smooth coffee. Under the pressure of water, all the ingredients of the coffee are separated by the phenomenon of absorbing hot water through a soft compacted coffee. Water carries solutes, oils, and even insoluble substances into the cup.
There are two basic layers of espresso separation: the crema layer and the liquid layer.
Crema layer made of CO2 foam is surrounded by water and oil. Crema also includes coffee and emulsifying oils found in coffee beans. This layer can be very bitter and have a lively debate that should be stirred before drinking to mix the layers together or not.
The main component of separating espresso is the liquid formed by solutes, gases, and insoluble substances. This is the part that makes up the taste of the espresso we love.
Don’t think that this crema will be as soft as cream or peanut butter. It is a beautiful part of espresso shot but it is not really “delicious” as you think.
How to make Espresso?
For a delicious Espresso coffee, it is necessary to use a dedicated brewing machine, but if you do not have the experience with the mixing machine, you can follow the classic style by using a bottle phase called “Moka Pot” or “Moka Express”
However, the classical style seems complicated and requires a lot of technology so it is necessary to use an espresso machine to make delicious, simple and crema-rich espresso. In this machine hot water 88 ° C to 94 ° C is pressed at an initial pressure of about 9 bar (bar is a pressure measurement unit) through a finely ground coffee powder. The flow time must be 25 seconds. If the appropriate amount of water flows faster than the flavors are not dissolved, the water flowing through the coffee powder too slowly will have too much dissolved bitterness.
