I have never tried Nordic roast coffee, but would like to try it. I am thinking about ordering Wendelboe or Sey coffee. My hesitation is that when I ordered my grinder, an 804 Ditting with cast Sweet burrs, the Ditting person warned against grinding ultra light roasts. She did not use the term Nordic, because when I asked about Nordic, she was not familiar with the term. She called it ultra light or something similar. She said Ditting recommended against grinding such light roasts. She implied it might be okay from time to time but not something I would want to consistently grind - that is my assumption from a year old conversation so she might not have meant that and instead meant to never grind it. Either way I am cautious about grinding it at all.

Is Nordic roasted coffee so hard that it could harm, or excessively wear grinders?

I wouldn't worry about the burrs. They are rated for 8000 pounds of coffee. Lighter roasts and finer grinds may result in a marginal decrease in longevity. But assuming you grind a couple of pounds of coffee a week (100 pounds a year) it would take you 80 years to wear out the burrs. It could however be that grinding lighter roasted coffee puts more stress on the motor. Given that this is a bulk grinder you may not want to continuously grind large quantities of light roasted coffee which could overheat the motor. I'd ask for clarification from Ditting, but I think the burrs should be fine. Many of us grind light Nordic style roasts on cheap Baratza grinders and they handle it fine for home use.

Ironic. I searched for my grinder and Nordic roast as search terms and one of the first results was the Nordic Barsita Cup tournament where my grinder was one of three that was allowed for the competition - the competing baristas could only use on of those three grinders:

Is it the Peak or are we talking 804 grinder?

Peak has problems with ultra light/Nordic roasts, just like the K30's before it (and allot of others from different manufacturers), so I have heard a similar warning about those specific grinders before. But be aware the warning is for use in a commercial environment, not in a home setting, so it should be no problem with using the lightest of roasts.

However neither 804 or 807 series should have those issues, there are a few cafes in my area that run these for both filter and spro with Nordic roast, they have experienced no issues, in fact they say they had fewer issues with those grinders then any other grinder they had before. So I would no be worried, your not gonna run these like a cafe, and people do use Nordic Roast in much less capable grinders. However it might shorten the lifespan of the grinder, but your probably never going to get near its max in a single lifetime, even if it reduces lifespan.

Kr804 but with Sweet burrs. Someone from Wendelboe replied that it is same grinder they use. He recommended running it before pouring beans into it for single dosing, not as any preventive caution, but he said it would make a more uniform grind. I used to grind that way but started putting beans in first. It never crossed my mind but it makes sense it would be more uniform sense the first few beans would get ground at a different speed and torque as most of the other beans if you put beans in first. Plus easier on grinder to turn on first, so I will go back to that.

I have a much lesser grinder, a Eureka Mignon Specialita, and am currently pulling a Sey Burundi that keeps overpowering it. I turn it on with coffee in it, dial it finer, and then when I start it again at that setting the motor won't turn on unless I make the grind coarser.

Which is to say, here's an example of a Nordic roast being hard on a grinder.

Yeah it's a good idea to turn it on before dumping the beans into the grinder, I have done this ever since I started SD. Yes there are theories that it deliver a more uniform grind, however I don't think it's been completely proved yet, and how the bean is fed to the burrs might also play a part.
