- We discuss how both grind size and packing characteristic determine the permeability of a coffee bed.
- We explain the concept of jamming and how it determines the degree to which we can compress the puck when we tamp.
- We explore what factors contribute to the onset of jamming and how grinder design might influence compaction.
- We look at ways to overcome jamming, to allow tighter packing in the coffee bed.
