3.Has one touch cappuccino
With one press of a button you can create a cappuccino.
4.number of grind settings
A higher number of grind settings gives you more flexibility when choosing the fineness of your ground coffee. The particle size is important as a grind which is too coarse can produce weak tasting espresso, whereas a grind which is too fine can lead to a bitter taste.
A 3-way solenoid valve relieves the portafilter of pressure and moisture after the extraction. This produces a dry puck which can easily be removed afterwards. It also means that you don’t have to wait for the pressure to equalise, so that you can make back-to-back coffees.
6.Has a pre-infusion function
With a pre-infusion function you get a low pressure of water before it ramps up to around 9 bar of pressure. This gently expands the grinds to get a smooth extraction and to help prevent channeling in the cake.
