A “configuration” is the way the machine operates, or the way the barista interacts with the machine to produce espresso.
More manual configurations allow baristas closer engagement with brew parameters like pre-infusion and pressure. More automated configurations allow the barista to program a repeatable output and give more of their focus to customer engagement. The style and volume of your business will be crucial in deciding which configuration to choose.
