About Mahlkönig
Mahlkönig has led global coffee grinding for a century, founded in Hamburg, Germany in 1924. Now part of the Hemro Group alongside Anfim, Ditting and HeyCafé, Mahlkönig grinders are trusted behind bars from independent specialty cafés to national commercial roasters. This is a brand built on German engineering precision, and the E65W GbS carries that reputation into one of the most connected grinders on the market today.
The Product
The Mahlkonig E65W GbS Grind By Sync Espresso Grinder is a commercial grinder built around two technologies working together: Grind-by-Sync (GbS), which lets the grinder communicate directly with a compatible La Marzocco espresso machine, and Grind-by-Weight (GbW), which doses every shot by real-time weight rather than time. It's designed for specialty cafés and multi-barista teams who need the same shot quality regardless of who's behind the machine. This is the future of café workflow — where your grinder and your espresso machine work as one system, not two separate guesses.
Key Features
65mm Special Steel Flat Burrs (Consistent Extraction)
The E65W GbS grinds through a set of 65mm special steel flat burrs, tuned for uniform particle distribution. That consistency is what gives you flavour clarity and a balanced shot, grind after grind.
Grind-by-Sync Technology (Smart Machine Integration)
Pair the E65W GbS with a compatible La Marzocco commercial machine and the grinder automatically adjusts burr distance to match your target shot profile. Every barista pulls from the same recipe, whether it's your opening shift or a second location entirely.
Grind-by-Weight Dosing (Precision You Can Trust)
A built-in load cell weighs the grounds as they drop, dosing by weight instead of time. It removes the guesswork and drift that come with timer-based dosing, so every dose lands on target.
Disc Distance Detection — DDD (Micrometric Adjustment)
Dual sensors track burr position to 0.001mm, giving you a level of grind-size control that timer- and dial-based grinders can't match.
Active Cooling System (Flavour Preservation)
An active cooling system keeps the burrs from overheating during back-to-back service, protecting the aromatic compounds in your coffee that heat can strip away.
Mahlkönig Sync App & Connectivity (Remote Management)
Wi-Fi and USB connectivity link the grinder to the Mahlkönig Sync app, so you can set up recipes, monitor performance and roll out changes across multiple machines or sites without touching each grinder by hand.
88.3mm High-Resolution Display (Clear at a Glance)
A wide-angle, high-resolution display puts grind settings and dose status in clear view from either side of the machine — no guessing at a dim screen mid-rush.
Illuminated Adjustable Spout (Mess-Free Dosing)
The adjustable spout lights up to guide grounds straight into the portafilter, keeping your bar clean and your workflow quick.
Who It's Built For
The E65W GbS is built for specialty café owners and multi-barista teams who want every shot to taste the same, no matter who pulled it or which shift it was. By combining Grind-by-Sync automation with Grind-by-Weight precision, it removes two of the biggest sources of shot-to-shot variation in a busy service.
Whether you're training new baristas or running the same recipe across multiple sites, the E65W GbS delivers consistency — automatically.
