The Mahlkönig X64 SD is Mahlkönig’s compact single-dose home grinder for users who grind beans by portion while still wanting to cover a wide range from espresso to cold brew. It combines 64-mm steel burrs, stepless grind adjustment, and a single-dose workflow designed to minimize retention.
64-mm steel burrs
The Mahlkönig X64 SD uses 64-mm burrs made of special steel. Depending on the grind setting, Mahlkönig specifies an average grinding speed of around 2.5 to 6 grams per second. For espresso, the manufacturer states at least approximately 3 grams per second.
This makes the X64 SD significantly faster than many small home single-dose grinders, while remaining considerably more compact than the brand’s professional commercial grinders.
Single dose instead of a permanently filled hopper
With the X64 SD, you weigh the beans before grinding and add only that amount to the grinder. This is particularly useful if you frequently switch between roasts or want to store beans in individual portions. A bellows is part of the design and helps move any remaining grounds out of the chute.
Anyone who uses the same house blend every morning and wants maximum speed without pre-weighing may find a hopper or grind-by-weight grinder more convenient. Single dose is therefore not a quality level, but a workflow choice.
Stepless grind adjustment at the micron level
Mahlkönig describes the grind adjustment as stepless and finely adjustable. The range extends from fine espresso to coarser methods such as French press and cold brew. The lid also includes guidance for various brewing methods.
This makes the X64 SD particularly interesting for users who want to cover multiple brewing methods with a single grinder. When switching from very coarse back to espresso, you should nevertheless reproduce the setting carefully and adjust it if necessary.
X64 SD or E64 WS?
Within Mahlkönig’s home range, the X64 SD and E64 WS are two completely different concepts. The X64 SD is designed for single dose. The E64 WS uses a bean hopper and grind by weight. If you frequently switch between beans, the X64 is more flexible. If you use the same beans every day and want to grind directly to the target weight as quickly as possible, the E64 WS is more convenient.
How compact is the X64 SD?
Mahlkönig specifies approximately 14.3 cm in width, 24.9 cm in height, and 25.3 cm in depth. The net weight is around 4.8 kg. For a 64-mm grinder, this is exceptionally compact and makes it easier to integrate into smaller kitchens.
Is the X64 SD only suitable for premium machines?
No. A high-quality grinder can also make sense alongside a Profitec GO 2.0 or Gaggia Classic E24 if you plan to upgrade the machine later. The taste advantage does not come from the machine and grinder having the same price, but from being able to adjust the grounds precisely and reproducibly.
Conclusion: Flexible 64-mm grinder for single-dose users
The Mahlkönig X64 SD is particularly strong if you want to combine 64-mm burrs, single dose, and multiple brewing methods in one compact device. Its advantage lies less in prestige than in everyday flexibility: weigh the beans, grind them fresh, and switch quickly between coffees when needed.
At BaristaYOU, we primarily recommend it for home baristas who deliberately want a single-dose workflow. Those who prefer a fast hopper workflow should instead compare the E64 WS, Eureka Libra, or other grind-by-weight solutions.
