Description

Engineered to Impress, Designed for Home

The Mahlkönig X64 SD is for the home barista who refuses to be locked into one bean, one brew method, or one routine. With zero retention, 64mm special steel flat burrs, and micron-level stepless adjustment, it delivers café-grade consistency in a compact, single dose format — then gets out of the way when you're done.

Switch from a fine Ethiopian espresso to a medium pour-over grind in under a minute. Load exactly what you need. Leave nothing behind. The X64 SD is purpose-built for the way freshness-focused home brewers actually work.

Freedom to Switch. Precision to Dial In.

Zero Retention Design: The X64 SD is engineered to leave virtually no grounds behind between doses. Every grind starts clean — no stale coffee from the previous session affecting your cup. The included bellow makes purging the chamber effortless between bean switches.

64mm Special Steel Flat Burrs: Flat burrs produce a significantly higher proportion of uniform-sized particles compared to conical burrs, translating directly to cleaner flavor, more consistent extraction, and greater dosing accuracy. These are the same burr spec Mahlkönig uses across their professional lineup, manufactured at their Hamburg facility.

Stepless Micron-Level Adjustment: The intuitive dial knob runs on a scale of 0 to 12, with infinite adjustment between any two points. Espresso lives at 0–2, filter at 2–7, coarse methods from 7–12. Because it's stepless, you can make the micro-adjustments that actually matter for espresso dialing — not just click between pre-set positions.

Swappable Hopper System: Three hopper attachments are included and swap in seconds — the standard 30g anti-popcorning lid for single dosing, an 80g bellow for purging and larger doses, and a 100g hopper extension when you want more capacity. No tools, no fuss.

About Mahlkönig

Founded in Hamburg in 1924, Mahlkönig has spent a century defining what precision grinding means for specialty coffee. The X64 SD Single Dose Home Grinder is engineered in Zürich, Switzerland, with burrs manufactured at Mahlkönig's own Hamburg facility — the same production line that supplies their professional commercial grinders. Every unit is conceived, assembled, and quality-checked in-house, from start to finish.

Frequently Asked Questions

What is a single dose coffee grinder and why does it matter? A single dose grinder is designed to grind only the exact amount of beans you need for each brew, with no large hopper full of beans sitting idle. This means maximum freshness for every cup and the freedom to switch between different coffees without cross-contamination. The X64 SD's zero retention design takes this further — virtually no grounds are left in the chamber between doses.

How does the zero retention design work? The X64 SD's burr chamber and grinding path are engineered to minimize how much coffee stays behind after each grind. The included bellow lets you purge any remaining grounds with a simple squeeze before you change beans or brew methods, keeping each dose clean and accurate.

What is the grind range on the X64 SD? The stepless dial runs from 0 to 12 and covers the full range of brewing methods — from fine espresso (0–2) through filter and pour-over (2–7) up to French press and cold brew (7–12). The built-in grind size guide on the inside of the lid makes it easy to find your starting point.

What espresso machines does the X64 SD pair well with? The X64 SD works with any home espresso machine and is a natural fit for the prosumer machines in our lineup — including the Lelit Mara X, Breville Dual Boiler, Ascaso Steel Duo, and Fiorenzato machines. Its compact footprint fits comfortably alongside virtually any countertop setup.

How is the X64 SD different from the Mahlkönig E64 WS? Both use 64mm flat burrs, but they serve different home baristas. The X64 SD is optimized for single dosing, bean switching, and allround brewing — espresso through cold brew. The E64 WS is dedicated to espresso and adds Grind-by-Weight (built-in scale), Grind-by-Sync (auto-adjusts with compatible machines), and app connectivity. If espresso is your main focus and you want automated precision, the E64 WS is worth the step up. If you switch beans and brew methods regularly and want the freshest possible dose every time, the X64 SD is the better fit.

How long do the burrs last? At a median grind setting, the 64mm special steel flat burrs are rated to approximately 500 kg of coffee. Actual lifespan depends on grind size, bean density, and roast level. Signs of wear include grounds running coarser than expected or warmer than usual after grinding.

How do I clean the X64 SD? Mahlkönig recommends cleaning with food-safe grinder cleaning tablets (such as Grindz) at least once a week. Run the tablets through the grinder as you would coffee beans to clear oils and residue from the burrs and chamber. The exterior can be wiped with a damp, lint-free cloth. Avoid chemical detergents on any surface.

Can I use the X64 SD for methods other than espresso? Absolutely — it's designed for allround use. The stepless dial covers everything from espresso through cold brew, and the zero retention design means switching between fine and coarse settings doesn't leave over grounds behind. Use the included dosing cup for coarser filter grinds to keep things clean.

Where is the X64 SD made? The X64 SD is engineered in Zürich, Switzerland and manufactured in Mahlkönig's own facilities in China. The burrs are produced at Mahlkönig's factory in Hamburg, Germany. Every unit goes through in-house quality control from design to final assembly.
