Burr coffee grinder Graef CM1116 — 310 W, 220 g bean hopper, iron colour

The Graef CM1116 is a burr coffee grinder designed for consistent, repeatable results in home and small office environments. It combines a 310 W motor with a 50 mm hardened steel disc grinder and a 220 g bean hopper to deliver steady grinding performance. The metal housing in iron colour and a machine weight of approximately 5.1 kg provide stability and reduced vibration, while a measured sound power level of about 60 dB keeps operation comparatively quiet. The grinder offers stepless grind adjustment and an integrated anti-clumping system to support a wide range of preparation methods.

Advantages

The 50 mm hardened steel discs ensure uniform particle size and a high grinding rate, supporting both espresso and filter preparations. The stepless adjustment wheel on top allows precise tuning of grind fineness to match bean type and extraction method. A timer-based dosing option provides repeatability for consistent shots, while the minimal dead space reduces retention and preserves freshness. A removable, height-adjustable stainless steel portafilter holder enables hands-free grinding for portafilter use and can be fitted with a support pad to protect and stabilize the portafilter.

Suitable for

• Home baristas seeking consistent grind quality for espresso and filter coffee
• Small offices where a compact, reliable grinder is needed
• Users who require hands-free dosing into a portafilter
• Coffee enthusiasts who value adjustable, stepless grind settings

How to use

Fill the 220 g bean hopper with fresh coffee beans and set the grind fineness using the stepless adjustment wheel on the top of the unit. For portafilter grinding, attach and adjust the height of the stainless steel portafilter holder and hook the portafilter into place; you can grind hands-free by using the timer-based dosing or start grinding manually for single doses. For ground coffee collection into a container, remove the portafilter holder and position the container under the dispenser. Clean the hopper and grind path regularly to avoid oil and residue build-up and follow safety instructions in the user manual when performing maintenance.

Usage recommendations

Use freshly roasted beans stored in a cool, dry place and adjust the disc setting incrementally when changing bean origin or roast level. For espresso, start with a fine setting and make small adjustments to achieve the desired extraction; for filter coffee, move toward a coarser setting. Regularly remove residual grounds from the portafilter holder and wipe the dispenser to maintain consistent dosing and to minimise taste transfer between different coffees.
