Differences between the Mahlkönig E65W GbS and the E65S GBW
The Mahlkönig E65S GBW was the first professional espresso grinder with integrated Grind-by-Weight technology: a high-precision load cell measures the ground coffee in real time, performing up to 6,000 readings per second to deliver the exact grams set in the recipe with exceptional accuracy. On top of this foundation, it features the Disc Distance Detection (DDD) system, which defines the grind size based on the actual burr distance, and Portafilter Detection, which automatically recognizes the portafilter and recalls the associated preset, simplifying the barista’s workflow and reducing errors.
The Mahlkönig E65W GbS was developed as an evolution of this platform: it retains the 65 mm flat burrs, the Grind-by-Weight logic, and the suitability for high-volume workflows, but integrates the Grind-by-Sync system. This allows the grinder to communicate with a compatible espresso machine or a Sync Scale and, based on the actual extraction times, automatically adjust the grind to maintain the target recipe. In practice, weight control is combined with in-cup time control, ensuring even greater consistency throughout the entire working day.
Features of the Mahlkönig E65S GBW vs E65W GbS
To get a clear view of the differences, it is worth summarizing the main features of the two models.
Mahlkönig E65S GBW – Main Features
- Grind-by-Weight technology with integrated load cell for real-time gravimetric dosing.
- Up to 6,000 measurements per second to ensure precise adherence to the grams set in the recipe.
- Disc Distance Detection (DDD) system to set grind size based on the actual burr distance.
- Portafilter Detection: automatic recognition of the portafilter and recall of the associated preset.
- 65 mm flat burrs made of special steel, optimized for espresso.
- Continuous grind adjustment for precise micro-tuning.
- High-resolution display with programmable dose profiles.
- Compact design, quiet grinding, and engineered for high-volume café workflows.
Mahlkönig E65W GbS – Additional Features and Advantages
In addition to inheriting almost everything that makes the E65S GBW a benchmark (65 mm burrs, Grind-by-Weight, DDD, portafilter recognition, ergonomics, and speed), the Mahlkönig E65W GbS introduces a series of advanced functions that place it on a higher level:
- Grind-by-Sync system: the grinder communicates with a compatible espresso machine or Sync Scale and adjusts the grind based on actual extraction times.
- Automatic grind correction to maintain consistent recipe parameters throughout the day.
- Native integration into the Sync System, designed for modern management of cafés, chains, and roasteries.
- Faster and guided calibration, with “intelligent” logic that reduces downtime and trial-and-error adjustments.
- Enhanced capability for data collection and management of usage and extraction metrics (depending on system configuration).
From a product line perspective, the Mahlkönig E65S GBW is gradually being phased out in favor of the E65W GbS, which is set to become the reference platform for those seeking not only precise dosing but also automation, repeatability, and integration with new extraction technologies.
Where to buy the Mahlkönig E65W GbS
One of the most critical aspects of espresso preparation is grind size. If the coffee is ground too coarsely, the water will flow through too quickly, resulting in a weak, watery espresso. On the other hand, if the grind is too fine, extraction slows down, making the coffee bitter and over-extracted. Those using pre-ground coffee should be careful to choose the right grind size for their machine. Those who grind fresh beans have the advantage of being able to fine-tune consistency, achieving more reliable and personalized results.
