Preinfusion timing and pressure
How preinfusion timing and pressure influence espresso extraction, flow dynamics, and final cup quality.
Pressure applied
Pressure and flow profiling curves
How pressure and flow profiling curves influence espresso extraction, and how baristas and researchers use them to optimize flavor and consistency.
Manometers and flow meters
The roles of manometers and flow meters in espresso machines, how they function, and how baristas can use their readings to monitor extraction.
Pressure profiling hardware
How different espresso machine hardware designs enable pressure profiling, and how this impacts extraction control.
Preinfusion and blooming espresso
How preinfusion and blooming techniques affect espresso puck saturation, extraction uniformity, and flavor outcomes.
Darcy-style intuition for flow in beds
