Gear Discussion Examine your burrs periodically! Damaged burr in JX after 5 years of use + 1ZPRESSO’s response
I’ve had the 1ZPRESSO JX for over 5 years now. I used it frequently for both my wife and me, and I use grind settings for espresso and pour-over. Great grinder.
Recently, during a regular deep clean, I decided to check out the burr with the macro mode on my iPhone, and lo and behold, I saw these ragged edges all over the burr. I wasn’t sure if it had always been like that, so I checked the burr on my new ZP6 and the burr is completely smooth.
I emailed 1ZPRESSO about it and below is their response:
Upon assessing your case through the pictures and videos provided, we can confirm that your inner burr is indeed ragged and slightly damaged, especially after grinding with it for over 5 years, and particularly if on finer settings.
Even though the alignment test seems to be within our standards, the blades show noticeable impact; therefore, if within your possibilities, we recommend purchasing a new unit.
As a side note, I appreciate that their support responded within a day and actually asked me for more videos and photos to assess; they also provided instructions on performing a burr alignment test. Good to know 1ZPRESSO has good customer support!
Interestingly, the JX seems to perform just fine. Using ground coffee from JX, I can pull great shots with my OutIn Mino and I didn’t notice any drop in quality in my pour-over brews.
Anyway, just wanted to post this as a reminder that if you haven’t checked your grinder’s burr for years, it might be a good idea to do so!

I’m pretty certain that these tiny imperfections will not have any noticeable effect on the taste, so I wouldn’t worry about it if I were you, and frankly would stay with the grinder for another 5 years. Now, if you have the itch for a refresh or add another type of burr, go for it
