80mm flat burrs, sub-micron alignment, built for the obsessed
the EG-1 Mk.3 is a single-dose grinder built around 80mm flat burrs with a patented blind-shims alignment system that achieves sub-micron burr parallelism. variable RPM, 5-micron stepped adjustment, magnetic burr mounting, and near-zero retention mean it moves from espresso to filter without purging or recalibrating. it is a precision instrument first, kitchen appliance second, priced accordingly at around $3,973 to $4,095 depending on retailer and region.
what it does well
- sub-micron burr parallelism via patented blind-shims alignment reduces channeling and uneven extraction
- magnetic burr mounting allows quick swaps between core, db2, and ultra burr sets
