Espresso Grinder Maintenance and Burr Replacement

April 25, 2012

time for a change

If you can’t remember the last time you changed your espresso grinder burrs then chances are they could be dull. In fact, if you grind coffee, and I’m sure you do, then your burrs are slowly dulling each and every time you turn on your espresso grinder. This goes for all the your bulk grinders too, though their burrs tend to last significantly longer.

“SO WHEN DO I CHANGE MY BURRS?“

THE OFFICIAL ANSWER:
The easy answer is to change your burrs using the grinder burr manufacturer’s recommendations.

Mazzer Mini (58mm flat burr) – change at 660lbs coffee throughput
Mazzer Super Jolly (64mm flat burr) – change at 880lbs coffee throughput
Mazzer Major (83mm flat burr) – change at 1300lbs coffee throughput
Mazzer Kony (63mm conical burr) – change at 1640lbs coffee throughput
Mazzer Robur 110V (71mm conical burr) – change at 1700lbs coffee throughput
Mazzer Robur 220V (83mm conical burr) – change at 1800lbs coffee throughput
La Marzocco Swift (64mm ceramic flat burr) – change at 3300lbs coffee throughput
Anfim Caimano (75mm flat burr) – change at 1300lbs throughput
Burr life is calculated by burr size and the amount of coffee put through each grinder. While there are recommended grinder burr life spans, these will vary for both flat and conical burrs, the burr material, and size ( i.e. cutting surface area) of the burr. Smaller grinders use small burrs. For example, the Mazzer Mini uses a flat burr set 58mm in diameter, this cutting surface sees a lot less action than the Mazzer Major flat burr set which measures 83mm in diameter.

PREMATURE WEAR.

Premature burr wear can be caused by rocks, nails, etc., that aren’t removed in the roasting and bagging process. Motor shaft and/or bearing damage can also accelerate burr deterioration.

THE COFFEE PROFESSIONAL’S APPROACH TO BURR LIFE:

For the serious coffee professional the manufacturer’s recommended replacement standards take the burrs far past their personal threshold of quality. The extreme perspective might call for one to change their burrs at the half-life. So your 880lbs becomes 440lbs and so on…

We suggest to our customers that you just be aware of the condition of their burrs. If you are quality orientated and find yourself particularly sensitive to negative effects dull burrs can have on espresso flavor or consistency, Espresso Parts recommends to start looking for signs of wear beginning from 50%-75% of the recommended burr life. (See chart above)

It’s a fine line. As long as things are looking and tasting great you are probably good to go.

WORN BURRS. THINGS TO LOOK FOR.

  1. Grind consistency. Are your grounds similar in size with very little variation?
  2. Taste. Does your espresso taste flat no matter what you do?
  3. Burr edges. Do they feel dull?

PROLONGED LIFE?

To prolong the life of your burrs keep them clean. We find that Urnex Grindz does a terrific job of cleaning the burrs and removing lodged solids and oils.

Removing, thoroughly cleaning, and re-installing grinder burrs regularly will also help extend their life.

LASTLY…

Brand new burrs can require a breaking in or “seasoning” period before they achieve the consistency you might desire. Its a good idea to save a few pounds of old coffee so that you have something other than fresh coffee to break those bad boys in. Mazzer Robur burrs are probably the most notorious for requiring such a break in period.
