What makes a coffee grinder,
the Ultra Grinder?

Low retention and static
If you have invested in an expensive single dosing grinder before, you know how frustrating it can be when your grinder retains grounds and the coffee doesn't make it into your portafilter due to static.
Retention on this grinder is consistently less than .1 g of coffee often with no RDT, partly due to the precision machining of the grinder, but also because of the clever chute system designed for the coffee's exit.
Both parts of the chute are magnetic, so they can easily be removed for cleaning or getting that last bit of coffee out.
Best In class grind consistency
The more consistent the grind is, the better the extraction. This grinder is capable of getting 23-25% extractions with espresso which is almost unheard of.
With huge 98mm burrs this grinder is ready to take even the lightest of roasted coffees at the lowest RPMs.
Because the servo motor has an incredibly short shaft, and the machining tolerances are very small, the runout on the moving burr carrier is less than .0005".
The Ultra Grinder is designed so that the upper burr carrier is 100% independent from the adjustment mechanism. They are separated by a high quality, German manufactured roller bearing to ensure smooth movement of the adjustment mechanism. The upper burr carrier plate is held in place by high tensile strength springs, pushing the carrier up into the adjustment mechanism, allowing it to be locked in place without needing a set screw. This also prevents any movement of the adjustment funnel. Since the adjustment system is independent, there is no way for the upper carrier to move when the grinder is on which means no coffee can get in the threading. Even the best other high end grinders on the market could potentially move under this stress.
The Ultra Grinder also uses a proprietary alignment system that allows us to make adjustments to compensate for the tolerance stack of all of the parts, making this grinder better aligned than anything on the market, out of the box.


Quiet operation
Only 20dB at rest, which is about as loud as rustling leaves. It clocks in at only 50dB when grinding.
Grinds beans quickly, consistently and quietly so you can experiment with different brews all morning without waking up your partner.
Sleek Design and quality build
Designed and assembled by coffee nerds for coffee nerds.
Stow away the power supply with 5 feet of hideable cable. The PSU is cleverly designed to be standalone from the grinder to keep your counter top clean.


Simple to use, outstanding results
What goes in your grinder comes out, every time.
No more wasting time and coffee changing grind sizes. The Ultra Grinder is easy to dial in and adjust grind settings with no extra work or cumbersome tools.
