Check out the full review by Coffee expert Matt from Lifestyle lab to listen how much he loves this system!

The Mahlkonig X54 is an excellent coffee grinder with an awesome taste profile but it suffers from massive grind retention making it unusable for single dosing. With the Single Dosing Kit from SingleDoseBrew, you can cut down grind retention by up to 99%, so you get fresher grounds every time. Plus, easily switch between coffee beans with almost no retention between changes, giving you the freedom to enjoy different flavors for you and your other half. The V2 now comes with an innovative bean gate to ensure consistency with every grind.

The Mahlkonig X54 Single Dosing Kit features:

• Reduced grind retention by up to 99% from the grinder to your portafilter!
• The new V2 version includes an innovative bean gate to control the release of beans once the motor reaches full RPM, ensuring consistency of grinds every time.
• The Single dose hopper lets you grind beans as you need them. No more stale overnight beans.
• Comes with a commercial grade silicon coffee grinder bellow. 
• Extremely tough silicon bellow tested for thousands of pumps. This helps to flush grinds stuck in the grind chamber and chute. Get class leading low retention for your grinder!
• Holds up to 80g of beans.
• Less bulky than the original hopper.
• Plug and play replacement for the original hopper.

Feature Highlights

The V2 version of the SingleDoseBrew X54 Single Doser features a built-in gate system that optimizes grind consistency by ensuring the grinder reaches its maximum speed and torque, before the beans are dropped in.

A simple lift of the doser opens the inner gate allowing beans to flow in to the grind chamber. A second internal chamber allows all the beans to drop in nearly instantaneously, after which a narrow channel guides beans into the grind chamber to gradually allow a limited number of beans to allow every bean to be ground evenly and prevent overcrowding.

The V2 also features a new double seal inner funnel which prevents stray grounds from leaking out of the grind chamber into gaps between the upper burr and the chassis. This also ensures the maximum air pressure through the new air jet slots, which pushes air through thin slotted openings, enhancing the blowing pressure from the bellows.

These thin slotted openings also prevent back pressure where ground fines go backwards into the main bellow chamber and also reduce pop-corning for the last few beans that would be ground.

Safety is also ensured with the locking ring that includes a push switch which is only activated when the upper single dosing mechanism is fully screwed in. This prevents stray fingers from ever reaching the grind chamber. In the V2, the push switch has been further improved to prevent it from falling out during installation.

Beautifully finished with the handcrafted wooden lid, the V2 SingleDoseBrew Single Doser gives your Mahlkonig X54 a classy OEM look, which matches perfectly against any high end wood finished espresso machine. Talk about function and aesthetics!

Performance Test

The test was conducted by grinding 10 grams of beans one after another over 3 rounds, with and without the Single Doser and Bellow. The test shows wildly varying grind weight results without the single doser because of the amount of grind retention as well as old grinds being dislodged into the portafilter. The Single Doser and Bellow reduces this retention, so there would not be much left over to be dislodged or reduced between grinds, ensuring a much more consistent grind weight between grinds.
