Electrical Compatibility

The EG-1, as with all of our electrical products, are designed to work anywhere worldwide without a transformer. 90-240v, 50-60Hz, we have you covered. CE Certified.

They all use C13 style connectors (same as a computer), so they can be localized with just a cable. This is also an advantage as these cables are readily available in shorter lengths for kitchen countertop use. We currently send the correct cable for your country when available (US, AU, EU, UK styles only), but it may ship with a US style cable based on cable availability at time of purchase.

Flat Burr vs Conical

The EG-1 is our premier flat burr disc grinder. There is an incredible amount of information on the web surrounding the question "which is better -- flat or conical?". In short, there is no concrete answer, as this really comes down to personal preference. A couple of things that can be said about each are:


Conical Burrs

It is our belief that conical burrs are great for their all-around flexibility in making good coffee. Think of them like a tennis racket with an enormous sweet spot that always feels just about right, but never channels 100% of the swing's power. They will give you the power to make amazing coffee with margin for error, but might not pull out every single complex note of a very sophisticated coffee. They work great on all styles of coffee, espresso to pour-over.


Flat (or disc) Burrs

These are for when you want to dial in with the precision of a scalpel to get every single origin note possible from your coffee. Our CORE burrs do this with precision and clarity, both for espresso and pour-over coffees. Our ULTRA burrs reduce fines to the point they are virtually unusable for traditional espresso, but outstanding as a dedicated pour-over burr. Our BASE burrs are unique in that they are flat burrs, but act very much like conical burrs with a lot of mouthfeel and a bimodal distribution. See more about all three burr sets here.

Details Make The Difference

We set out to build the perfect flat-burr grinder. Zero-retention. Perfect for filter, impeccable on espresso. The EG-1 is the result of that effort. Your search is over.

5 Micron Stepped Adjustment

Simple stepped adjustment easily takes you from Turkish-fine to v60 ready, and back again without the need to dial in a second time. This allows you to keep several types and styles of coffee and go back and forth without needing to clean, dial-in, or purge with extra beans in between.

Maintenance & Cleaning

The EG-1 cleaning process is as easy as it comes.  The grind chamber can be opened, thoroughly cleaned and resealed a matter of seconds. The top and bottom funnel caps form a clam shell grind chamber and are secured together using sets of strong rare earth (Neodymium) magnets. The caps easily snap off the front of the unit, providing the barista complete and unobstructed access to the burr set and wiper system. The best part is that this deep cleaning doesn't affect grind size adjustment or burr alignment.

The upper dosing dish has also been designed to be easily removed for cleaning. Held in place by a pair of Neodymium magnets and a set of stainless steel pins, the dish can be quickly removed from the grinder for a quick wipe down.

At the end of the shift, in the middle, or even when changing the beans, it’s fast and easy to clear the grinder of any lingering residue. Ease of cleaning offers more options for using different roasts in high volume environments or in other service situations such as cupping rooms or roasting labs.

Burr Alignment

A common complaint with commercial grinders is the inability to check or adjust burr alignment. In the majority of machines, burrs are buried deep inside the grinder which makes a visual or mechanical inspection impossible. If there is an issue, evidenced by uneven burr wear or inconsistent shots, manufactures don’t offer adjustment mechanisms to calibrate a burr set after assembly.

We designed the EG-1 to make it simple for the user to both verify and adjust burr alignment. Without the use of any tools, the EG-1 burr set is fully accessible in less than 20 seconds. Ease of access to the burr set facilitates both regular maintenance and daily cleaning. If necessary, adjustments to alignment can be made with a 4mm metric hex key in a matter of moments without having to disassemble the grinder.

Burr Replacement

We reinvented the burr mount to make this easier to do than with any other commercial coffee grinder. With a 4mm hex tool and 5 minutes spare time, you can swap and perfectly align your EG-1 burrs to any of our 3 burr options depending on the grind profile you are going after.
