Coffee Roasting Explained! One batch, beginning to end

This is Coffee Roasting Explained! From the beginning of one roast to the end, I talk you through what we are doing and how that is affecting the coffee. From adjusting the heat/burner setting, to using software to read the temperature, to using sensory data (ie: look and smell) to determine when to end the roast, we're talking about the drying phase, development time, first crack, and more. Enjoy this roast-along in the Black & White Coffee Roasters roastery!
Machine: 15k Loring Falcon
Software: Cropster
Coffee: Colombia Santiago Caro, Washed Chiroso
I'm attempting different video/editing methods, so this one is "narrate-as-I-go." Apologies ahead of time for the background noise (roasteries are loud) and my "umms" and "uhhs" while trying to think in the moment. Maybe I should make another similar video and try voiceover narration - what do you think?

Great video! Would love to see what happens after the roast as well (e.g. optical sorting, dividing, packaging) and also what happens after that informs your curve development (e.g. sampling, cupping, and then how that informs what you change on the curve)! --edit-- nevermind, found some other videos that show the sorting and packaging! Would still love know (broadly speaking) how you choose to adjust your curves/ROR etc based on what you taste!

Fun to watch. Not sure you are using much on the sensory side. The roaster smelled the coffee for the first time just before dropping the batch. We train to smell at every color change and many times between as much as they want to learn the smells of every coffee origin going through the roaster. Looking and smelling the beans as much as needed to keep sharp. We are mostly a manual roaster. Small batch. Very hands on, no computers. Hand data logging - a lost art these days. Thanks for the video.

@roasterkat Жыл бұрын

Good to hear how you do things. And I agree - there are many ways to roast coffee. Some like to go fully manual. At the place I work now, we have found the most success with a combo of sensory and computer tracking. As a production roaster, my job is to carry out the roast as I've been trained to do at this company. So that's what I do! If you find success other ways, good on you, and keep doing what works.

@weetbixiron 2 жыл бұрын

Good stuff, love your channel :) If your roast profile is specific to the bean, why do you have to manually adjust the burner percent to match the target, can it not be preprogrammed? Or would that be inaccurate because of ambient temp influence?

@roasterkat 2 жыл бұрын

Great question! Some people do what’s called a “Power Profile” where they roast with the same control every time. But for most of us using the temperature, each batch changes, even just slightly every roast. You can program it with this machine, though most machines don’t have that capability. We do roast on automatic for some coffees and not for others - depends on how well the automatic control works with the beans. It’s not perfect for every coffee.

So i just started roasting on a loring and i know the air cool feature is one of the things theyre proud of but i never heard yall turn it on. And Im Also struggling with my coffee hitting first crack at around 410F and then the RoR just sky rockets but i have my burner at 20 (lowest) im pulling my hair out and would love some friendly advice.

@roasterkat 2 жыл бұрын

Welcome to the lovely world of Loring! We don't use the air cool feature - you're correct. We have found we don't need it for our coffees. For FC at 410 and RoR taking off, here are a few questions: - how long are your roasts? - how big are your batch sizes? - are you trying to roast to light/medium/dark? - what processing method are most of your coffees? A few things to try: - less energy in the system earlier on - lower charge temp - cut burner to 20 earlier (before FC) - use bigger batch sizes

@roasterkat 2 жыл бұрын

It also seems strange that your FC is happening at 410. How confident are you that FC is actually happening at that moment and not earlier? How are you determining FC?

Is there any difference in taste between convection and conductive systems?

@roasterkat 2 жыл бұрын

That depends. There are many other factors that go into the flavor than just the type of roasting system, so yes and no. If you sung know how to use them correctly, yes. But you can also get them to taste [nearly] identical if you know what you’re doing.

The temperature increases during the roast, from a low point of around 200 degrees F to 410-420 degrees F

@roasterkat 5 ай бұрын

It's a hybrid between fluid bed and drum. And yes, heat application is tied to airflow so you only have one variable to control. (Though you can consider batch size and charge temp variables as well.)

Really enjoy this style of delivery, and I think the real sounds add to the experience. Also appreciate your explanation of using sensory queues to determine when to drop the batch. Can you describe some of the things you look for to determine if development is high enough? Does a particular scent show up and then go away? Another somewhat related comment: sometimes I smell fruit in the trier, and I wonder if that means I just volatilized that flavor and sent it out the exhaust. Is that crazy talk? 😅 Thank you for a great roast-along!

@roasterkat 2 жыл бұрын

Thanks for the notes! As far as "what" I smell... it depends on the coffee. I don't think that if you smell fruit that means you just destroyed it and got rid of it. If that was the case no coffees would taste fruity, know what I mean? It's more the change in smells to "toasty" more or less for me. Some people say they detect acetic acid (vinegar) aroma at First Crack but I haven't smelled that consistently (maybe I'm not a super smeller). It's more getting used to the smell of each particular coffee and how it corresponds to the development that you're after. Haha sorry that's not too helpful!
