Jerichos were manufactured in China and sold by Coffee Bean International from outside Portland. Rising manufacturing costs a couple years ago resulted in CBI discontinuing these grinders and replacement parts, including burrs, which are all long gone. If this is the specific grinder I'm thinking about, the same burrs were used in the KitchenAid Proline grinder. I would love a set of burrs if you happen to find any
We used the Proline grinder and pour overs at public functions to demonstrate to consumers that they are just as capable as we at making delicious coffee.
