From espresso to pour-over coffee preparation, the EG-1 is Weber Workshops's 80mm premier flat burr grinder for specialty coffee, now upgraded to the Mk.3 edition. The EG-1 Mk.3 ships with your option of two burr sets, both magnetically mounted. For everything from pour-over to espresso, we recommend the CORE burr set. For pour-over & filter only brewing, we highly recommend the ULTRA burr set for the highest clarity. If you purchase a second set of burrs at the same time as the grinder, you'll receive an automatic discount in the cart ($100 off on CORE, $150 off on ULTRA).
