Eco-friendly, non-electrical, portable espresso machine! Makes premium quality espresso anywhere: whether on holiday or on a business trip, in the countryside or on the sea, in your kitchen or in the garden, the Nanopresso is a true must have! It's slightly smaller than it's big brother, the Minipresso, but don't let size fool you. Even though the dimensions are less it delivers twice the pressure (16 bars instead of 8) to extract even more flavours from your favourite ground coffee. It even has a bigger water tank, 80mls which is 10mls more than the Minipresso. You will need to add hot water - either using your own kettle or for true portability a vacuum flask (neither kettle nor the vacuum flask are supplied). Once you have added your ground coffee and hot water simply release the piston from its carry position and press it back in to control the amount of extracted coffee - a few pushes is generally all that is required to achieve the optimal extraction pressure. A rich and bold espresso is then released into your espresso cup for you to enjoy.
