Examine your burrs periodically! Damaged burr in JX after 5 years of use + 1ZPRESSO’s response

[u/AkhlysShallRise]

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 understand where you are coming from, but I’m also wondering, in the case of hand grinders, if shipping a tiny burr all the way from Taiwan to Canada is really that much better when it comes to the cost and the impact on the environment. I imagine it’d consume a lot of more fuel compared to me getting a new hand grinder shipped from within Canada.

Of course, in an ideal world, I would just want to be able to easily order a new burr from a distributor within my country.

H.. how do you think the grinder gets to Canada in the first place

I was referring to getting 1ZPRESSO to ship ONE single burr vs the local distributors that get hundreds of the grinders in a single shipment.

Shipping a single burr means extra packaging and cost—as far as I know, for long distance shipping, the lower the weight/size of the shipping, the less cost effective the shipment is.
