The barista express. A barista will quickly tell you that the most important ingredient to deliver an amazing espresso is to use fresh beans and to grind them as close to the time of use as possible. The in-built conical burr grinder allows you to grind only what you need directly into the portafilter. With a dedicated hot water outlet, impressive steam pressure and dual and single wall filters, you'll move from novice to barista in no time at all.
