Graef CM 800 review (2026)
Graef CM 800 is a electric grinder that suits Espresso, Moka pot and AeroPress. From €167.52 delivered to Germany, prices vary by country.
A cheap, sturdy espresso-first grinder with very fine steps. Reviewers flag loud noise, heavy retention and a fiddly burr adjustment, and Kaffeemacher would not recommend it.

Pros and cons
Pros
- Coffeeness and Sonntagmorgen both report a very even grind and fine adjustment steps.
- Both German reviewers call the build robust and forgiving of user mistakes.
- Kaffeemacher notes it can grind fine enough for espresso, which it says is unusual in this price class.
- Portafilter holders in two sizes give a grind-on-demand workflow, according to Coffeeness and Sonntagmorgen.
Cons
- Kaffeemacher measured about 8 g of grounds staying inside, and calls that a lot.
- Coffeeness and Sonntagmorgen both describe the sound as loud and unpleasant, and note static scattering grounds.
- Reaching espresso range means opening the grinder and shifting the upper burr ring, and Coffeeness says a wrongly seated ring gives coarse gravel.
- In Kaffeemacher's blind triangle test the Graef shot was picked as the worst espresso in every set.
What owners report
- Retention and old grounds. Reviewers who used it for a long time report hidden piles of old coffee after each grind. The first dose after a bean change carries old grounds.
- Adjustment ring moves by accident. The main ring turns easily. Coffeeness mentions an owner who marks the setting with a pen.
- Hard to switch brew methods. Because the fine screw shifts the whole range, moving between espresso and French press is awkward.
What experts measured
- Kaffeemacher measured about 8 g retention and reported dissolved solids of about 17.9 percent, against up to 21.5 percent for the other grinders in its test.
Alternatives
Melitta Calibra
Coffeeness and Sonntagmorgen both point filter drinkers away from the Graef; the Calibra is aimed at filter with a built-in scale.
