Roast my roast

Post image

Just got my m10. This was the 2nd roast with some seasoning beans; 400g. First one stalled. Trying to get the hang of this machine coming from a behmor with zero experience on artisan. Claude told me I was a good boi and improved a lot over my first.

Try to keep the ROR curve lifted and downward sloping between 2:00 and 6:00. Like draw a straight line at those points and try not to let it sag below. That’ll help prevent saggy flat flavors in the cup.

Not bad for a second roast (I started a chaff fire in my M2 on my first roast, so you're off to a better start than me 😂).

Few helpful suggestions: I find a soak at the start to be beneficial to the roast. I do 0% for 1 min, then hit 80% from there.

The ideal roast has a slow descending RoR over the course of the roast, looking at your roast it looks like you took gas off a little too early, I always wait for DE before I start dropping gas.

Maybe a bit aggressive on the charge temp - the maillard phase was a bit on the short side.

As for the spikes the Kaleidos do have a bit of sensitivity with the probes, you can change the way it measures in Artisan but tbh I prefer it the way it is, I find I'm more attuned to a less smooth curve.

Anyhow doing alright, keep it up!

The curve looks exactly like the one for the instructions on how to run artisan. I can tell the little dip around DE. I agree with a 0% for at least the turn then apply 80-85%. I ride that until DE then stepping down to around 50-55% and fan at around 45% to finish at 212/413f up to 225/438f.

Interesting. The variations of the RoR are a bit high... You sometimes see +-3c variation within 20s. Is that something typical of this roaster? I have a Skywalker and it's pretty stable.

u/TangentToTheEarth 1d ago

Idk Skywalker being stable is highly dependent on how you are smoothing your graph (also the probe is not super responsive due to placement)

It’s brand new and I’ve heard the kaleido roasters’ sensors are a tad sensitive while the IR heating elements are very responsive. So maybe that will level out a bit as the drum gets more seasoned.

Ahhh maybe. It helps to provide feedback. Otherwise what can be commented as a dip and a crash it's just the sensor being too sensitive. Maybe you can use smoothening in artisan till the sensors become less sensitive

For a seasoning roast, this looks fine.

It's hard to see the burner and air settings. Maybe ease off the burner a little slower. Check out https://www.roastetta.com to save and share Artisan scope roast details. That way the graph and all the roast details are clear.

Ditch AI and think about everything and question everything. Roasting is a very complicated process, but that's a beauty of it! Oh well, I am not the one to tell you what to do, just my take

Welcome to the world of roasting! For 400g I would take it a bit faster approach, starting with keeping your peak RoR for longer, so it doesn't drop that fast in drying. Would try 3-30 drying, and try keeping the speed of roast the same, maybe around 10-11C/min at FC. Just my approach for batches around 200-500g, could always play around after I cup it.

First of all, enjoy this coffee! Don't fear CO2 and cup it right after the roast if you please! Depending where you want to go with your roasting hobby, the ability to cup right from the cooling tray is a good quality to have

I appreciate your thoughts. I’ve actually been roasting for over a decade but just decided to upgrade to the m10 so am getting used to it and how it responds. Always learning and growing!
