The main difference between the E65W and E80W grinders is their size and burr size. The E65W has 65mm burrs and a smaller footprint, while the E80W has 80mm burrs and a larger build. Both models share the same advanced features.
This video reviews the Mahlkönig E65W and E80W GbS espresso grinders. While designed for commercial use, the presenter highlights the innovative technology potentially applicable to future home models. The focus is on the grinders' advanced features, including grind-by-weight, grind-by-sync, and toolless burr calibration.
The transcript indicates a taste difference between the 65mm burrs (E65W) and the 80mm burrs (E80W). The presenter states the 80mm burrs offer "higher extraction and sweetness," and that the "body and sweetness you get from these burrs is fantastic," describing the difference in sweetness and aroma as "huge compared to other espresso burrs." However, no specific taste differences beyond sweetness and body are detailed for the 65mm burrs.
