Espresso have to literally “pressed”. This method of brewing using hot and steamed water through roasted and ground coffee with high pressure (ideally 9-10 atmosphere) makes coffee 15 times more dense than coffee compared to other countries. A cup of espresso is black and concentrated juice with a very high concentration. Therefore, the level is limit to less than 20 ml. A delicious espresso cup needs a layer of reddish brown foam floating on the face called crema (cream).

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.

To make a delicious and crema-rich espresso, use an espresso machine. In this machine hot water 88 ° C to 94 ° C have pressed with an initial pressure of about 9 bars through a finely ground coffee powder. The flow time must be 25 seconds.
