2 reviews for 500g/1lb Gas Coffee Roaster
Ian Picco, Director of Coffee at Topeca Coffee
It is SO much different than my cast iron and IR roasters, it’s like going from a 72’ Cadillac Eldorado to a Porche 911. The heat transfer is very fluid. So that took a little getting used to. This is going to be great for teaching purposes, especially our Heat Transfer class.
The fan speed control is super sensitive, which I heard from other folks prior to getting the machine. But even with the fan turned off, I’m getting a lot of draw through the drum. At 50 on the frequency gauge (the minimum working setting) I am pulling a lot of energy out the drum. If I go to 100 I start sucking beans. On the physical air control dial that is a range between ~40-45. Super narrow. I’ve also noticed that the frequency creeps up and down, which is annoying, because you think you have the air set where you want it, walk away for a minute, then return to see your frequency has crept from 50-70 on the gauge and your ROR is plummeting. I’ve concluded that I will need to install an inline damper on my stack to compensate for natural vacuum that exists in my roasting area. Hopefully this will gain me a little more range with the machine fan.
I am also going to replace the gas ball valve with a valve that is a little more controllable. Ball valves are great for on/off operation, but it gets a little difficult when trying to execute precision changes in controlling pressure variance.
Other than those two things, I’m enjoying the machine. I’m getting close to nailing down a workable/repeatable 100 g sample roast profile. I cupped a few samples I roasted on Friday, and they came out pretty darn good, just a few little tweaks needed.

Loving my North Roaster. When I originally ordered my roaster I was planning on it being destined for the basement. Once my wife saw it she fell in love with it and it now sits proudly in our Dining Room on a Stainless Steel cart (so it can easily be rolled into the kitchen for roasting). I have been roasting for about 15 years, mostly on a Behmor and the last couple of years on a Sonofresco. Not blaming either machine but I had gotten into the auto pilot mode and without realizing it settled into coffee that probably wasn’t as good as the machines were capable of. The North Roaster has gotten me back involved with my roast and brought fun back into roasting. Overall the machine is an extremely high quality piece of equipment that looks great. The staff at Mill City was very patient with me and all of my questions (most questions were related to roasting or Aritsan software vs the roaster itself – which is very straight forward). If you are ready to step up to a machine that can last you a lifetime I would definitely recommend this machine!
I forgot to mention that the quality of our coffee has stepped up a few notches and still have lots to learn!
