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 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 enable you to make amazing coffee with margin for error, but might not pull out every single note of a very complex coffee. They work great on all styles of coffee, from 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 filter coffee. Our ULTRA burrs reduce fines to the point they are virtually unusable for traditional espresso, but outstanding as a dedicated option for filter coffee. See more about our burr sets here.

Maintenance & Cleaning

The EG-1 cleaning process is as easy as it comes.  The grind chamber can be opened, thoroughly cleaned, and resealed in a matter of seconds. The top and bottom funnel caps form a clam shell grind chamber and are secured 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 multiples coffees in high volume environments or in other settings such as cupping rooms or roasting labs.

Burr Alignment

A common issue 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. Manufacturers generally don’t offer adjustment mechanisms to calibrate a burr set after initial assembly. This makes it very difficult for users to align their grinders. 

We designed the EG-1 to make it simple to both verify and adjust burr alignment. The burr set is fully accessible in less than 20 seconds without the need for any tools. Ease of access to the burrs 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 a spare 5 minutes, you can swap and perfectly align your EG-1 burrs.
