Mahlkönig Grind-by-Sync Commercial Espresso Grinder

The Mahlkönig Grind-by-Sync (GbS) is the most technologically advanced commercial espresso grinder in the Mahlkönig range — engineered for specialty cafés where consistency, speed, and intelligent automation are essential from the first shot to the last. Available in two configurations — the E65W GbS with 65mm burrs and the E80S GbS with 80mm burrs — the Grind-by-Sync combines gravimetric precision dosing, wireless machine connectivity, electronic burr adjustment, and Disc Distance Detection into a single, streamlined workflow tool that makes reliable espresso extraction achievable at scale.

At the heart of the system is Mahlkönig's Grind-by-Weight technology, measuring coffee dose 6,000 times per second via an integrated high-precision load cell. The result is accurate, repeatable dosing directly into the portafilter — eliminating the shot-to-shot variation inherent in timer-based grinding. And with Sync System connectivity, the grinder communicates directly with your espresso machine to automatically align grind settings with your target extraction parameters, closing the loop between grinder and machine in a way no traditional grinder can.

Why the Mahlkönig Grind-by-Sync is in a Class of Its Own

Most commercial grinders require baristas to manually dial in grind size repeatedly throughout the day as temperature, humidity, and bean density change. The Grind-by-Sync is designed to reduce that burden — dramatically. Burr calibration that previously took over 10 minutes now takes just 10 seconds with a few taps on the display. Dose accuracy is handled automatically. And with Sync System integration, the grinder and machine work in concert rather than in isolation.

• Grind-by-Weight (GbW) technology — integrated load cell weighs dose in real time at 6,000 measurements per second for unmatched accuracy and repeatability
• Mahlkönig Sync System — wireless connectivity between grinder and compatible espresso machine; automatically adjusts grind settings to maintain consistent extraction parameters throughout service
• Disc Distance Detection (DDD) — patented technology that ensures accurate and repeatable burr distance positioning, eliminating guesswork from grind adjustments
• Electronic burr adjustment — motorised, software-controlled burr positioning for micro-precise grind size changes with no manual ring adjustment
• Burr calibration in ~10 seconds — vs 10+ minutes on conventional grinders, dramatically reducing downtime during service
• 65mm special steel burrs (E65W) — 1,400 RPM idle speed (50Hz), burr grind life approximately 800kg at median settings
• 80mm special steel burrs (E80S) — larger burr set for higher-volume environments requiring faster throughput
• 1,800g bean hopper capacity — generous hopper suitable for continuous high-volume service
• Integrated portafilter detection — automatically triggers grinding when the portafilter is inserted, reducing barista effort and improving workflow speed
• Active temperature management — powerful motor and integrated cooling maintain stable grinding temperature during peak service
• High-resolution digital display — large, intuitive interface for grind settings, dose programming, and real-time feedback
• Cloud-enabled connectivity (E80S GbS) — allows multi-location coffee businesses to monitor grinder performance and manage recipes remotely across sites
• Compatible with Sanremo, La Marzocco, and other Sync-enabled espresso machines

Who Is the Mahlkönig Grind-by-Sync For?

The GbS is the right tool for coffee businesses where espresso consistency, operational efficiency, and technology integration are strategic priorities:

• High-volume specialty coffee shops that pull hundreds of shots per day and need reliable dose accuracy without constant manual adjustment
• Multi-location coffee businesses that want to standardise espresso recipes across sites using cloud monitoring and remote recipe management
• Flagship café operations pairing the GbS with a Sync-compatible espresso machine for a fully automated extraction workflow
• Baristas and café managers who want to reduce dial-in time, eliminate dose variation, and free up attention for customer-facing service
• Coffee roasteries with retail bars requiring consistent grind performance across multiple barista shifts

The Problem the Grind-by-Sync Solves

In any busy café, espresso consistency degrades over the course of a service. Burr temperature rises, ambient humidity shifts, and bean density varies — each of these subtly alters the grind and the resulting extraction. Conventional timer-based grinders cannot compensate for these changes automatically; they require manual intervention from an experienced barista who notices the drift and adjusts accordingly.

The Grind-by-Sync addresses this at two levels. First, Grind-by-Weight dosing removes dose variation from the equation entirely — every shot receives the exact same mass of coffee regardless of grind setting or bean density. Second, Sync System connectivity enables the espresso machine to feed extraction data back to the grinder, which can then auto-adjust to keep shots on target. The result is a closed-loop system that maintains espresso quality throughout service with minimal barista intervention.

Frequently Asked Questions

What is Grind-by-Weight technology and how does it work? Grind-by-Weight uses an integrated high-precision load cell scale built into the grinder to measure the mass of coffee being ground in real time — at 6,000 measurements per second. The grinder stops automatically when the target dose weight is reached, delivering a consistent and accurate dose directly into the portafilter on every single shot, regardless of changes in grind setting or bean density.

What is the Mahlkönig Sync System? The Sync System is Mahlkönig's wireless connectivity platform that allows a GbS grinder to communicate with a compatible espresso machine. The espresso machine shares extraction data with the grinder, which can then automatically adjust its grind setting to maintain consistent espresso extraction parameters. This eliminates the need for manual dial-in throughout the day and is compatible with a growing number of machine brands including Sanremo and La Marzocco.

What is Disc Distance Detection (DDD)? DDD is Mahlkönig's patented technology for precisely measuring and setting the distance between the burr discs. It ensures that grind size adjustments are accurate and repeatable, removing the mechanical variability found in traditional burr adjustment systems and enabling the electronic control that makes rapid calibration possible.

What is the difference between the E65W GbS and the E80S GbS? The E65W GbS uses 65mm special steel burrs and is suited to most specialty coffee bars and high-volume independent cafés. The E80S GbS uses larger 80mm burrs, offering faster grinding throughput for the highest-volume environments or multi-grinder setups. Both models share the same core GbW, Sync System, and DDD technology.

How fast is burr calibration on the Grind-by-Sync? Burr calibration — the process of adjusting and verifying burr distance — takes approximately 10 seconds on the Grind-by-Sync via the touchscreen interface. On conventional commercial grinders, this process typically takes over 10 minutes, making the GbS a significant operational advantage during busy service.

Which espresso machines are compatible with the Sync System? The Sync System is designed as an open platform and is compatible with a growing list of espresso machine brands including Sanremo and La Marzocco. Compatibility continues to expand.
