The Mahlkönig E80W Grind-by-Sync (GbS) espresso grinder replaces the E80S Grind-by-Weight (GbW) and retains full Grind-by-Weight functionality with added features for improved control.
While the GbS name highlights its ability to pair with compatible La Marzocco machines (AV or ABR configurations) for dynamic burr adjustments based on target extraction time, it works as a standard Grind-by-Weight grinder with any espresso machine. This ensures precise dosing and versatility across all setups.
The E80W GbS includes cloud-enabled connectivity and an intelligent algorithm for automated burr adjustments. Baristas can adjust settings manually or use the grinder’s syncing capability for consistent results with minimal effort.

This grinder functions perfectly, despite the dent and scratch on its exterior. It will be shipped in its original packaging; detailed photos of the imperfections are provided for your review.

Includes Free Shipping and a 12-month parts warranty.

  • Grind-by-Sync (GBS) technology - Synchronizes grind size with real-time dosing for optimal extraction.
  • 80 mm Special Steel Burrs - Delivers consistent grind quality.
  • High-Precision Burr Gap Adjustment - Features micrometric electric motor control for grind size adjustments accurate to a single micron, making setup quicker and easier than traditional methods.
  • Quiet Grinding & Powerful Motor - With active temperature control for high-speed performance.
  • Cloud-Enabled Connectivity - Electric burr adjustment, allowing manual fine-tuning or automatic syncing with espresso machines for optimal extraction. Accessible through the Mahlkonig Sync mobile app.
  • Patented Disc Distance Detection (DDD) - Enables accurate settings of the degree of fineness.
  • Time Savings and Quality Assurance - Integrated through Portafilter Detection.
  • Adjustable Illuminated Spout - Provides a clean and centered coffee outlet.
  • 88.3 mm Display - With a high-resolution wide viewing angle.

    X64 SD
    Rated 5 out of 5 stars
    Great grinder!

    Loving my purchase of the X64 SD. I am a single doser, needing to switch back and forth between decaf and caffeine beans, and I like to drink different coffees during the day. I upgraded from a Sette 270 which I loved for its performance in a single dosing setup, but it is the loudest grinder I have ever used. So, when the X64 SD arrived, I was happy to give it a go. It is faster, quieter and I no longer have to have a WDT step in my routine. Maybe the only issue I have is that I like to grind directly into my portafilter and it does tend to spray more particles around, so my cleanup of the area is a bit more often. Zeroing the grinder is a must, mine shipped with a healthy safety tolerance so the first grinds were less than 1 on the dial to get good grinds. After zeroing there is a better range between 1 and 2 for my range of coffees. Plenty of range for dialing in. It is solid, retention is not very high, about what I expected. The 64mm flat burrs are producing nice grinds. All in all, a great upgrade!

    E80S/T (New Open Box)
    Rated 5 out of 5 stars
    Built like a tank

    It’s huge, but we love it. So easy and intuitive to make calibration adjustments. We are in a busy hospital and this grinder keeps up with us.
