Mahlkönig X54

What it does well

It is built well. Kaffeemacher praises the workmanship, the secure mount and the display, and describes repairability and spare-part supply positively. Mahlkönig rates the motor for more than 25,000 shots.

The espresso is good. Kaffeemacher found "clear espresso shots, relatively low unpleasant bitterness, and good extraction behavior." Sprudge rated the shots among the best its reviewer had made on a Rancilio Silvia.

It is easy to use. Sprudge found that "all the functions are easily decipherable" without the manual. Its 10-second timed dose landed at about 17 g, varying by roughly 0.1 to 0.2 g.

Adjustment is stepless. Kaffeemacher found the dial has no clicks or resistance, and called it more flexible than many classic espresso grinders.

Where it falls short

Retention is the main complaint. Kaffeemacher measured 7.6 g at an espresso setting on a 2021 unit. After Mahlkönig changed the flapper, it measured 4.1 g, and says early owners can swap the flapper at home.

Retention also behaves unpredictably. Kaffeemacher found powder sometimes clumps around the burrs and drops into a later dose. One shot came out at 16.5 g instead of 18 g.

It is not built for single dosing. Kaffeemacher found typical single-dose losses of 0.2 g, but outliers up to 1.2 g. About 20 g of beans also sit below the hopper slide, which slows switching coffees.

It is slow and tall. Kaffeemacher timed 16.5 seconds for 18 g. Sprudge says the grinder barely fit under an 18.5 inch cabinet, and calls the hopper "too large for home use."

Who should buy it, and who shouldn't

Buy it if you keep one coffee in the hopper and make espresso plus everyday pour-over. Sprudge rates it best for espresso and small-to-medium pour-overs. Kaffeemacher says anyone who re-weighs each dose "has a very good grinder."

Skip it if you single-dose or change beans often. Skip it too if you brew large Chemex batches. Sprudge found those needed the top of the range and still showed boulders.

If you want the best of both methods, consider two grinders. Kaffeemacher says it still prefers a separate grinder for espresso and for filter.

How it compares

The Eureka Mignon Specialità is another hopper grinder with timed dosing. It is more compact and focused on espresso, and reviewers of it stress how quiet it is.

The DF64 Gen 2 is a single-dose grinder with 64 mm flat burrs. It suits someone who changes beans often. See DF64 Gen 2 vs X54 for the dials.

The Baratza Vario+ is the closest like-for-like rival. It is also a 54 mm flat-burr hopper grinder with timed presets, aimed at espresso first with filter as well. It adjusts with macro and micro levers rather than a stepless dial.

Owning it

Mahlkönig publishes guides for flapper replacement, calibration and cleaning the grinding mechanism, plus a spare parts list. If you buy an early unit used, ask whether the flapper has been replaced.

Mahlkönig puts average burr life at about 500 kg. Our guides to cleaning a burr grinder and calibrating a grinder cover the routine jobs.
