Mahlkönig X64 SD Single Dose coffee grinder

The Mahlkönig X64 SD Single Dose coffee grinder is suitable for filter coffee. You can adjust the grind size steplessly between 120 and 1,500 µm. The grinding system made of hardened steel delivers a fine and even result, which is important for filter coffee.

The X64 SD is designed for Single Dose use. When switching between different single origins, the beans can be easily exchanged. Purging remains minimal most of the time. You get consistent results when dialing in. It is recommended if you often want to test different varieties.

The X64 SD features a stepless grind size adjustment from 120 µm to 1,500 µm. This covers the range for turbo shots (140–160 µm) and the required range for light V60 filter roasts (800–1,200 µm). The 64 mm flat burrs ensure consistent particle size and slightly more heat generation than conical grinders. For espresso you use about 10–15% of the adjustment range. If you regularly switch between espresso and filter, the X64 SD is one of the few Single Dose grinders that can uncompromisingly handle both applications.

The manufacturer's specification of 'under 65 dB' cannot be directly substantiated based on the Home-Barista posts. Many users find the X64 SD to be noticeably quieter in operation than classic grinders, but not particularly silent. Compared to a Mazzer Kony S, it appears to be significantly more subdued, yet still clearly audible. The RPM is lower than that of fast commercial grinders, which reduces noise. The grinder is suitable for an open kitchen, but it does not achieve nighttime silence. Some users report: quieter than Niche Zero or DF64, but without true whisper quality. Those who want it almost silent must resort to hand grinders.

The exact outlet height of the X64 SD for direct portafilter dosing is not specified in the available specifications. To check if the grinder can be used under your E61 brew group, it is advisable to make a direct inquiry with the manufacturer. Alternatively, many baristas use dosing cups when space is limited.

For espresso, models with 64 mm or 65 mm burrs are ideal. The E65W GbS is currently one of Mahlkönig's main café grinders and can handle 80–120 pulls daily with consistent quality. For home use the X64 SD is perfect: it grinds single portions fresh, has a 64 mm flat burr set made of hardened steel and you can adjust the grind steplessly from 120 to 1,500 µm. The ground coffee is very evenly distributed, which makes the espresso taste clearer and less bitter.

The X64 SD is specifically built for Single Dose. You only put in the beans you need, it grinds everything through and almost nothing remains in the grinder. This is perfect if you want to try different coffees without residues mixing. The E64 WS can also weigh single portions with grind-by-weight. Classic café grinders like the E65W have a bean hopper and are intended for continuous operation.

The X64 SD is ideal for home. It is compact, grinds fresh per cup and operates quietly under 65 dB. The E64 WS is the bridge between home use and a small café: more precise with grind-by-weight but more expensive. Both have 64 mm burrs which are completely sufficient for espresso. Important: Mahlkönig grinders are an investment. If you previously had an inexpensive entry-level grinder you will notice the difference in taste immediately.

The EK43 is legendary for both preparation methods. It has 98 mm burrs and delivers very consistent ground coffee from espresso to filter coffee. That is why it was used for years in barista championships. For pure espresso in a café there are now faster alternatives like the E65. The X64 SD at home covers both areas with its stepless adjustment from 120 to 1,500 µm. For filter coffee you simply set it coarser.

The number indicates the diameter of the burrs in millimeters. Larger burrs grind faster and generate less heat because the work is distributed over a larger area. 64–65 mm are standard for home espresso and in smaller cafés. 80 mm and above are intended for high throughputs in larger establishments. The X64 SD has 64 mm burrs made of hardened special steel. That is completely sufficient for precise espresso grounds.
