  „This espresso coffee has been packed into the portafilter in such a way as to create pressure that restricts the flow of water through the coffee. The pressure is created because the coffee is finely ground and the water is not free to flow quickly through the coffee. This is where I reintroduce the term BAR pressure. In order for hot water to be pushed through the ground coffee, the pump has to be able to generate serious pressure to overcome the resistance created by the packed coffee.“

As we move up the food chain of coffee machines, the types of pumps start to vary a little. In many higher end machines the common pump is a volumetric one. I wonít go into too many extra details on the properties of the volumetric pump.“

  „Espresso is often thought of as coffee's pure essence. Hot water is forced, under pressure, through finely-ground, dark-roasted coffee in a very short time to produce a strong, smooth demitasse (2 fluid ounce shot) of espresso. Successfully brewing espresso takes a lot of practice and the right equipment.“
