The Art of the Pressure Curve
Pressure profiling allows users to dictate how the pressure changes throughout the espresso shot. This might involve a pre-infusion phase at lower pressure to evenly saturate the coffee puck, followed by a ramp-up to peak extraction pressure, and then a controlled decline. This level of granular control enables the extraction of nuanced flavors and aromas that might be lost with a constant pressure approach. For the technically inclined, this feature opens up a vast landscape for experimentation, allowing them to mimic or even innovate upon established extraction curves and discover new flavor dimensions in their coffee beans.
Integrated Scales and Flow Meters: Data-Driven Brewing
To complement pressure profiling, some of the most technologically advanced espresso machines integrate in-built scales and flow meters.
