Espresso

Nine atmospheres of pressure, seven grams of coffee, 30 second of extraction to create an espresso of 25-30 ml volume. As the name indicates, an espresso is a cup of coffee prepared on the spot for immediate consumption. When brewed properly, it is an enormously complex drink with concentrated flavours and aromas that distinguish it from coffee prepared by any other method. Espresso is an extraordinary beverage and, like all extraordinary things, is very complicated in his structure. First of all, it is a solution, because it contains different elements (acids, proteins, sugars, fats and others substances). It is also an emulsion, due to the presence of oils, which hold aromas and give espresso his full body. Finally, espresso is a suspension, for the thick and persistence layer of foam that you can find on coffee surface. To coffee connoisseurs, espresso is the quintessential form of coffee; the purest way to enjoy its aroma and flavour at their maximum intensity; a tiny miracle of chemistry and physics that is as much art as it is science.
