THE PREPARATION |
Together with the tes, coffee is the most drunken drink in the world. The preparation and usage methods can be classified into 2 main systems:
1) infusion: when the coffee’s powder is left to macerate in boling water, like in the case of the Turkish coffee.
2) percolation: when the hot water flow is passed through the grinded powder, as though for the expresso, the moka pot and the Neapolitan coffees.
Among these methods, the expresso is the one which takes advantage of the 700 substances that form the volatile aromas, in fact thanks to the practiced pressure, it is possible to extract some of the oils and of the colloids which are responsable of the greater excitation of our senses of taste.
What are the advices to make such a coffee?
We suggest to follow the 5M (in italian language) to make a good coffee: blend, grinder-doser, expresso machine, hand and maintenance.
BLEND |
BLEND |
You have to choose it after a careful research, without using the yardstick saving only. A good blend is what makes the customers come to your coffee bar.
THE GRINDER-DOSER |
THE GRINDER-DOSER |
The grinders need to be regularly regulated during the operation to have a right degree of the flour milling which is often influenced by the moisture.A normal dose for a normal expresso, has to be extracted in 25/30 seconds. If the time exceeds the 30 seconds it is necessary to reduce the flour milling, the coffee has been ground too fine. If it takes less than 20 seconds to grind, it is necessary to bind the flour milling to slow down the water flow passing through the coffee powder.
THE EXPRESSO MACHINE |
THE EXPRESSO MACHINE |
The water’s temperature for the infusion – between 88° and 92°.
The pressure in the boiler – between 0,9 and 1,2 atm.
The pressure of the volumetric pump – between 8 and 10 atm.
