Mahlkonig E65S: 65mm Flat Burr Commercial Espresso Grinder

The Mahlkonig E65S is a commercial espresso grinder built in Germany for small to medium cafes and serious home baristas. Normally $2,700, now on sale for $2,399. It sits between the Eureka Atom 75 at $1,199 and the Mahlkonig E80 Supreme at $3,000 in the premium commercial grinder market.

This is a hopper-based grinder, not a single-dose machine. The 800g bean hopper and timed dosing system suit high-volume environments where speed and consistency matter more than retention. The 65mm hardened steel flat burrs, 3.5-4 gram per second grind speed, and sound-insulated casing define its performance.

The E65S is quiet for its class, stepless for precision, and programmable for workflow efficiency. It is not the fastest grinder available, an 18g dose takes roughly 4.5-5 seconds, but the trade-off is consistency and reduced noise. For cafes prioritizing a calm environment and reliable extraction, this is meaningful.

A GbW (Grind-by-Weight) variant is available at $2,750, adding load cell technology for weight-based dosing instead of timed.

What Is the Mahlkonig E65S

The E65S is Mahlkonig’s mid-tier commercial espresso grinder, manufactured in Germany with an aluminum body and steel internals. It targets coffee shops, restaurants, and dedicated home setups that need professional grind quality without the footprint or price of the E80 Supreme.

As one of the best commercial espresso grinders of 2026, it has earned recognition for combining compact size, quiet operation, and precise adjustment. The 65mm flat burrs produce uniform particle distribution for balanced extraction. The stepless micrometric adjustment allows dialing in with minimal waste. The six programmable recipes let baristas switch between beans or roast profiles instantly.

The grinder is not designed for single dosing. Retention is higher than modern zero-retention alternatives like the Niche Zero or DF64 Gen 2. The workflow assumes a full hopper, timed dosing, and regular purging between grind changes. For cafes, this is standard. For home users, it requires acceptance of waste and stale-ground risk.

Key Features

65mm Hardened Steel Flat Burrs

Precision-machined for uniform particle size and long life. The 65mm diameter balances speed and heat dissipation. Not as fast as 80mm burrs, not as slow as 50mm alternatives. The sweet spot for small to medium volume.

3.5-4 Gram Per Second Grind Speed

An 18g double shot takes approximately 4.5–5 seconds. Slower than the E80 Supreme’s 6-7g/s but faster than entry-level commercial options. The motor runs at 1,400–1,650 RPM with burr speed near 1,700 RPM.

Sound-Insulated Aluminum Casing

Reduces grinding noise significantly compared to open-frame competitors. Exact decibel ratings vary by environment, but the casing makes the E65S one of the quieter commercial grinders in its power class. Ideal for cafes where conversation matters.

Stepless Micrometric Adjustment

Single-revolution dial with infinite settings between finest and coarsest. No steps, no clicks, no guesswork. Micro-adjust for espresso dialing without overshooting. The dial is firm and precise, resisting accidental shifts during busy service.

Six Programmable Dosing Recipes

Store up to six timed doses for different beans, roast profiles, or basket sizes. Switch instantly between recipes via the digital touchscreen. Eliminates manual timing and reduces dose variance during rush periods.

Digital Touchscreen Interface

Displays current recipe, grind setting, and shot count. Simple navigation for programming and adjustments. Backlit for low-light environments. Less sophisticated than smartphone-connected competitors but reliable and intuitive.

800g Bean Hopper

Large capacity for high-volume service. Not airtight, beans stale faster than single-dose workflows. Best for cafes with high turnover or home users who finish a bag within days.

Ergonomic Portafilter Holder

Adjustable fork holds portafilters hands-free during grinding. Reduces barista fatigue and improves workflow speed. Accommodates various portafilter sizes and dosing cups.

Comparison with Similar Grinders

E65S vs E65S GbW

The GbW (Grind-by-Weight) variant adds Acaia load cell technology for weight-based dosing instead of timed. It costs $2750. The base E65S uses timed dosing, faster but less precise as burr wear and bean density change.

Choose the base E65S for speed and value. Choose the E65S GBW if dose accuracy to 0.1g is critical for your program.

 E65S vs Eureka Atom 75

The Eureka Atom 75 costs $1,199 with 75mm burrs and stepless adjustment. It is faster and cheaper but louder and less refined. Build quality and long-term reliability favor the Mahlkonig.

Choose the Eureka for budget and speed. Choose the E65S for noise control, precision, and German build.
