The Xbar is a compact and high-performance espresso maker built for true espresso enthusiasts, from beginner to expert. The machine features ultimate pressure control by using a simple yet powerful compressed air/gas system. It provides the ability to manipulate brewing pressure (between 0 and 12 bars, static or progressive) during the extraction process. Our goal is not only the professional quality espresso but also the way to explore the role that pressure plays in espresso extraction.
