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. Actually, it's best to limit the time between grinding and extraction to seconds, not minutes. That's why we've built a grinder into the Barista Express™ espresso machine. The in-built conical burr grinder allows you to grind only what you need directly into the portafilter. It's fully adjustable in grind size and dose, so you can tweak to taste. The patented Razor™ dosing tool trims the puck for consistent extraction, while PID digital temperature control delivers accurate water temperature throughout the extraction. With a dedicated hot water outlet, impressive steam pressure and single wall filters, you'll move from novice to barista in no time at all.
