You can now get extra-strong coffee without compromising on aroma. With the aromaDouble Shot function, two single espressos are ground and brewed, as opposed to one large espresso, This automatic process ensures that there is no bitter aftertaste, as less water means that less bitterness is released - ensuring that only the best of the beans make it into your cup.
The preparation of really good, aromatic coffee specialities is a delight - cleaning the milk system isn’t. Which is why Siemens developed autoMilk Clean. This fully automatic steam cleaning system activates after every drink, ensuring perfect hygiene and relieving you of having to clean the milk system every day. Milk residue simply doesn’t get a chance to develop - allowing you to just sit back and enjoy a great cup of coffee.
The high-quality ceramDrive grinder grinds the coffee beans to a very even consistency, allowing all the different notes to develop during the brewing process - for an exceptionally aromatic coffee experience. Unlike steel grinders, ceramic is very robust and stays sharp for longer, meaning long-lasting premium-quality coffee is guaranteed.
Thanks to the coffeeSelect Display, the perfect coffee experience starts the moment you switch on the machine. The large user interface presents an inviting selection of aromatic coffee and milk specialities that can be accessed by simply touching the sensor controls - making your coffee experience as seamless as possible.
