The NESCAFÉ® Dolce Gusto® machine heats water, which is passed at high pressure through a capsule of high quality coffee into the cup. NESCAFÉ® Dolce Gusto® machine uses up to 15 bar pressure, similar to coffee house machines to deliver a great cup of coffee every time. The coffee that is used in the capsules is made of premium 100% pure Arabica coffee beans.
The high pressure and capsule technology is designed to deliver an even distribution of water and pressure through the coffee to maximize the flavour. While traditional drip coffee machines operate at one bar of pressure (normal atmospheric pressure) and a number of other one-cup coffee machines operate at no more than two bars, the NESCAFÉ® Dolce Gusto® system can operate at 15 bars. The higher the pressure the more flavour is extracted from the coffee.
