Paper puck filters and channel control
How paper puck filters influence espresso extraction, reduce channeling, and affect clarity and mouthfeel.
Uneven extraction
Alignment checks and shimming
How to perform alignment checks on coffee grinder burrs and use shimming to correct misalignment for optimal grind consistency.
Recipe scaling for groups
How to scale ibrik and Moka pot recipes for serving multiple people while maintaining flavor balance and consistency.
Heat management and channeling
How heat control during Moka pot brewing influences extraction, and how poor management can cause channeling through the coffee bed.
Fines migration and flow restriction
How fines migration—the movement of tiny coffee particles during extraction—affects flow restriction, channeling, and cup quality.
Puck compressibility and porosity
How the compressibility and porosity of an espresso puck influence flow resistance, extraction uniformity, and cup quality.
