Filter permeability and resistance
How the physical properties of coffee filters affect water flow, extraction, and cup quality.
Water flow
Grind size effects on flow
How grind particle size influences water flow, extraction efficiency, and flavor balance in brewed coffee.
Percolation vs immersion dynamics
Understanding how water flow dynamics—percolation vs immersion—affect coffee extraction and flavor development.
Scaling vs etching in boilers
Understand the difference between scaling and etching in espresso boilers and how water chemistry affects them.
Depulping equipment and settings
This topic covers the equipment and settings used in depulping coffee cherries, how the process works, and why calibration is essential for quality and efficiency in washed coffee processing.
