I always wonder why coffee experts like John do not use SCA guidelines for levels of roasting. It is a much more effective way to judge your roast, ie city- to full city+. I have been roasting for about 15 years and everything John says is bang on!
Basically what I was able
To deduce from several hours of watching the Mill city roaster’s “Roaster Edication” playlist.
This is what I was lookin g fir to start off with, but I’m glad I watched all that other stuff as well.
Great Easy to understand tutorial! Thanks for making the roasting process much more straight forward!
Thanks for the tips. First time I’ve seen anything about the moisture loss percentage making with lvl of roast. Thanks so much that’s going to help me dial things in that much better.
Exactly what I needed! Excellent video and answered a ton of questions I could never find from other channels.
Glad to hear it! Happy roasting
Thanks for the informative and straight forward video of the roasting process. Very well presented and very helpful..
Extremely helpful;; how I wish I'd had the simple explanation two years ago. I stopped roasting two years ago due to it being too stressful as I wanted dark roast but ended up with either too light or burnt beans, because the information I had was too complicated is my roaster. But NOW I understand the precise process which is simple so I'm going to dust off my roaster, pull out the "green" beans and have another go, because I'm tired of crappy tasting "stale" coffee.
Great video! Loved how well you describe the process.
Love love love this!!!! What great knowledge. Str8 fwd and easy to understand. Thanks bro!
Great informative video, and straight to the important points.
Thank you for the clear and simple explanations!
Excellent video for beginners! Each word important, and nothing extra. Like!
Excellent and concise tutorial that answered many of my questions on roasting, since I’m a beginner!! Thank you very much!!! Subbed!!👍😎👍
Great info. Thanks for sharing.
🙏 thank you for sharing this with us 🙏
Oh my God this is soooo helpful. Thank you so much.
The quality of the content of your video was great. Very impressive and useful. Will be waiting for more updates. Keep posting.
Excellent tutorial. I’m ready to start!
Thank you so much for taking the time out to teach and help. It’s really appreciated! FR800 arrives tomorrow, so first roast tomorrow night. ;-)
That's amazing, have a wonderful time! As a great starting point, try these settings with the stock chamber:
Heat on 9 the entire time
Fan on 9 for 2 minutes
then
Decrease fan by 1 every minute until finished.
Enjoy
How did it go? I tried mine for the first time yesterday, and I'm drinking some of the best coffee I've ever had today. And, I live in a city with many very well respected roasters. I'm not a stranger to good coffee.
Lots of helpful info. Can’t wait to start my next batch.
Thanks! I have a Sonofresco fluid bed roaster and still have issues with the roast profiles....or I'm not very good with modifying them through the ADR software.
I get my best results when using sight, smell (which involves redirecting a portion of the exhaust air towards my nose) and hearing.
Your advice on different timing periods after first crack and the cool down window have given me a better perspective.
Am I right in thinking that a Sonofresco fluid bed roaster is over $3,000? I'm at the beginning stages of roasting. (First batch today!) Although it seems like a fun project, I'm not sure if I need a "real" purpose made roaster. Problem is, my wife and I love one really good mug of coffee a day. I'd actually like to drink 3 pots a day, but can't do that anymore!
Thank you. Great video👍👍👍🌟🌟🌟🌟🌟. Good and straight forward explaination.
Glad to hear that it helped you! Good luck with your coffee roasting journey!
Well explanation. Will try aim at that after the 1st Crack and going to stop it when starts to go for second Crack. Awesome. Gonna try it.
Home roaster facts. Excellent!!!!
Well Done. Bravo!
The total roasting time matters too, if you take too long the coffee starts to lose flavour, but if you roast too quickly, depending on the beans and the equipment, the batch can become uneven.
Brilliant thank you for the video very helpful ❤️👏🏾
Thank you so much! Happy roasting :)
Thanks. Great video.
Great video. Thanks a lot
Wow thanks forbm sharing information 😊
Thank you,I enjoy watching your video.
You're welcome! Good luck with your roasting
Man. It’s excellent.
Thank you for this important information I will give it a try.
Awesome video thank you!
Clear explanation, nice editing.
No wonder i saw in some video they jot down some notes. Thanks for the useful info.
You're welcome, I hope it helps!
Thanks sharing... great video
Perfect!! Better roasting video
Thank you!
you are a good man john dennery. thankyou and godspeed to you :)
Thank you and you are very welcome! I hope you really enjoy the coffee roasting journey!
I am learning so much from watching your videos. Thank you so much for sharing this amazing source of information. This one is quite helpful.
Thank you so much and I'm glad you enjoyed it! Coffee roasting has been such a treasure in my life, I hope you are really loving the process!
@@JohnDennerythis is awesome, i just got sr800 and this will help tremendously, thanks
What were your Fan & Heat lvls during process on this video
@@bbasevic So glad to hear that you're psyched! I always leave the heat on 9. Start with the fan on 9 for a few minutes and then begin dropping the fan speed roughly every minute or so until you start hearing first crack. You can fine tune this according to your voltage and ambient temperature but this will be an excellent default profile to play with. Enjoy the amazing journey :)
That super amazing explanation
success always for the chenel..
,👍👍
Great info
Great video
Another great lecturer in coffee roasting! Please include also the temperatures of each roast. And maybe your background plant could be a coffee tree. .
Love the idea of a coffee tree, just give me a few more years, hah! I've never used any temperature probes so I can't tell you what the bean temp should be at any given stage. The temp readout on the Behmor is useless and the one on the FreshRoast is helpful but inaccurate. I really just go off of total roast time, time to first crack, intensity and length of first crack, and then the % of weight lost. This has been enough to help me dial in the roasts to my liking.
Dope video!
Thanks!
Enjoyed your vidio, gave me a lot of good information
Glad to hear it! Good luck on your next roast!
Sure nice one
thank you very much :-)
Thank you so much more videos if you would
Very helpful. Does the process change much if you are using a hand roaster?
Thanks 🙂
Very helpful
Great information 😊😀 man thanks alot, please juat tell me where could we find this cool machine FR800 but it's nothing like this
Sweet Maria's has some in stock. It's called the Fresh Roast SR800
www.sweetmarias.com/fresh-roast-sr800.html
Great info JD. 😊
Thanks Kalen! Have you been roasting at home?
@@JohnDennery no, but watching you makes me think I should be.
A very straightforward video, I have the Behmor and agree about its limitations. With the FreshRoast, how can you hear 1st crack over the roaster noise?
It's much easier to hear in person, it's just hard to capture with my microphone. The fan is much louder than the Behmor but I'm able to hear even the weaker and fainter cracks no problem at all
Excellent! Thank you! Your way of explaining and detailing the process is exactly what I needed. Thanks!!
Thank you
Thanks for easy say
Nice video good info, how about the machine you use to roast?
For indicator, I look for oil. Its beautiful and delicious.
Liked liked liked a bunch if i could hit that button more than once. thank you for the calculation towards the end. This video was very help in understanding the roast level from light to dark. I'm new to roasting coffee from home using a popcorn coffee roaster so any new information is very much appreciated and put to work.
Thank you so much, I'm really glad this helped you! Coffee roasting is such a fun journey - enjoy that popcorn roaster! I hope you've been getting some great roasts dialed in
cool, let me try
Super helpful
Am a barista looking to get roasting lessons in uae
Hello bro, I'm a Barista too and wants to learn Roasting. Can I have your contact please?
I like your roaster, is it an air roaster, where can I order if from. Thanks for the info.
hey john what coffee roasting machine do you advise for batch sizes of larger than 15kg
Thanks for the informative and straight forward video of the roasting process. Very well presented.
You're very welcome. Happy roasting!
Do you weigh the roasted beans before or after cooling/removing the caff? How much weight does the chaff generally contribute?
I usually shake the chaff out and let the beans cool first. I’d be surprised if there was even 1 gram of chaff in a pound of coffee, it’s super light. Most of it just floats away during the roasting process
Hello, where did you pull this equation from? Looking for a guide from light to dark roast based on that calculation. Can you also change weighing from grams to oz?
Hi, this is just a mathematical equation to calculate the percentage of weight lost. I wouldn't do oz personally because you'll end up working with a lot more decimals.
There are no hard rules about which % correlates to each roast stage as this will change somewhat from bean to bean.
But I have found that, in general:
Light roast = 12.5% - 13.5%
Medium roast = 13.5% - 14.5%
Dark roast = 14.5%+
These values seem to be reasonably accurate for most of the coffee I've roasted. The one notable exception was a peaberry that lost about 18% moisture at a medium roast.
You'll have to dial this in for every bean you roast though. Just remember that the middle of first crack is a good place to start for a light roast. The end of first crack is a good place for medium. The very start of 2nd crack is dark. Roast to those points and then check the moisture. Repeat on your next roast and you'll be able to dial it in by going slightly longer or shorter on the roast.
I hope this helps! Have fun :)
This is very interesting! I want to start roasting when I buy a coffee shop, is the process any different in a commercial machine
The beans will still go through the exact same stages but you will have WAY more control. You’ll be able to preheat as much as you want, as well as quickly change the temperature up and down as desired. Plus you’ll have temperature probes charting the entire roast so that you can replicate the results you prefer.
For the two home machines I’ve used, I basically need to roast on full power the entire time. Commercial machines give you nearly endless options to play with. Sure sounds like fun! Best luck to you on becoming a masterful roaster!
@@JohnDennery thank you for your reply!
Hi John, sorry , i did not go through all the questions that may be be similar than mine, I want to know where you got hold of your home roasting device and what make it is, also what capacity it can handle? Thx DG
I'm using the Fresh Roast Sr800 with an aftermarket extended chamber (RazzoRoasting on Etsy). It does 1/2 lb at a time
i woudl have thought there would hav been more sound for the first crack. like does each seed have to emit this sound? or is that sound many seeds at once ?
It’s a bit hard to hear over the sound of the fan on this machine but it generally takes from 1-2 minutes for all of the beans to go through first crack. As long as the heat isn’t too low, you will hear all of them like a batch of popcorn
While you wait 3-7 days to off gas what do you store your beans in? Will it off gas in an air tight container or do we burp it like curing weed?
I generally just leave mine in a colander on the counter lol. I’m roasting small enough batches that last 4-5 days so I don’t really worry about it anymore. But I used to always wait until the second or third day to transfer to the airtight container. Seems like the CO2 would all disperse from the airtight container once you opened it but I can’t honestly say for sure
I am using a rotisserie in an air fryer @ 450 degrees. It takes at least 23 minutes to reach 1st crack. Does it matter how long it takes to get to first crack. I saw just over 6 min on your machine. I am roastin an organic Ethiopia Gera nano Challa wet processed. I have had some success, but noticed the end result tastes good, but is missing a full flavor one would expect in a freshly roasted coffee.
In my own experience, any roast that takes more than 13-14 minutes to complete has a negative effect on flavor. People often refer to these as being "baked". This happened a lot on my Behmor, which is why I much prefer the FreshRoast roasters. If there is any way to boost the temperature of your machine, or get it fully preheated before adding the beans, I would recommend trying to shave as much time off your roasts as possible and see how you like it. Keep in mind that most commercial roasts are completely finished in the 10-13 minute range. Keep experimenting and I hope you enjoy your results!

Great! What is the name of your roaster?
This is the Fresh Roast SR800
Where did you buy the machine?
What roasting machine do you use?
While waiting for 2 days after roasting, what do you use for storage?
I usually just leave it in a colander on my kitchen counter. Since I’m roasting smaller batches (1/2 lb) I don’t really have any problems with losing freshness. At some point on the 2nd or 3rd day I’ll transfer it to my airscape container
Pl share what machine to purchase for small scale business purposes.
I’ve only used small, home roasting machines but if I was going to upgrade I’d get the Aillio Bullet. This is fully capable of helping you with a small business. Some shops use 2 or 3 of them and it looks like an absolutely fantastic roaster!
aillio.com/?product=bullet-roaster-r1
Hi, at what temperature you set your roaster?
This roaster is a bit underpowered so I leave it on the highest heat setting the entire roast. It doesn’t give accurate temperature readings though so that’s all I can say
Where can I buy flavoring oils for roasting flavored coffee?
Hey, I really don't know anything about flavoring coffees at all but I hope you have fun researching and experimenting with it!
I often hear people saying they roast for X amount of minutes "from first crack". Does this mean when first crack literally starts, peaks, or finishes? E.g., I heard something say they roasted for 45 seconds from first crack, and apparently that is considered a very light roast.
Great question. They're talking about the amount of time from the start of first crack. Not from the first few outliers, but the actual start when you hear multiple cracks in a row. 45 seconds is a very short amount of time. I would generally aim between 1:30-2:00 depending on the batch size and the heat level (I go for ~medium). Hotter roasts progress more quickly so this won't always give you the same results but is a decent statistic for you to dial things in.
@@JohnDennery That's what I did with my SR800 yesterday when trying it for the first time with some organic Honduran beans. I continued to roast about 2 minutes after hearing first crack. Whatever it was I did certainly worked, because the coffee is amazing today. I just hope that wasn't beginners luck, and I can repeat it. lol
I didn't see what roaster you were using. It looks like a tube was added to a freshroast like roaster. What roaster were you using for this video?
Thanks
That was the SR800 with an extension chamber from Razzo Roasting (seller on Etsy). Highly recommended add-on for all freshroast users!
thanks
Where dd u purchase from your equipment and at how much
You can search for the Freshroast SR800 online. I think it was about $220 USD. I also purchased an extended chamber from Razzo Roasting on Etsy. Don't remember the price on that. It's been a really good setup for a few years now!
Thanks, John, very much. How about hands-on tutorials on skillet roasting?
You're very welcome! I do have one video showing a similar style roaster in action, which you can view here th-cam.com/video/0nQdt6f_Ljg/w-d-xo.html
I recently moved and only brought the FreshRoast and the Behmor with me so I won't be able to make any tutorials about that but if you follow the guidelines in this video and make sure you keep your beans moving, I'm sure you'll do great!
Steady heat application and consistent movement are the keys. Best of luck to you!
what to do when you cannot hear crack sound? my air Roaster's fan is too loud to hear anything else.
You'll have to rely on your other senses of sight and smell. Also you can pay close attention to timing compared to other roasts. If there is a way to get a temperature probe into your setup, that will also give you some accurate readings that will be useful. You may find in the future that different coffees crack more loudly due to their higher moisture content so hopefully you can get that experience to help you!
it looks so dark so early already after the first crack i didnt think it would be that fast
Do you have commercial roasting tutorials???
Hi, I'm just a home roaster! I've been lucky to learn a few things from a friend who is a professional but I really just love to research and experiment. Luckily with commercial equipment you'll likely have some sophisticated graphs and readouts you can refer to to dial things in but I don't have access to any of that so I'm just going on sight, sound, smell, time, and taste!
Great tips. I cringed/laughed at the necessity of explaining how you come up with the percentage. Must be a ton of math challenged ppl out there...
To cool, invest in a good fan.
The biggest issue with roasting coffee is smoke. If you can't solve that, you can't roast. Roasting generates significant smoke and I've found that hood vents on stoves are not capable of handling the smoke. Since this is such a big problem, I am puzzled why this issue isn't addressed in videos such as this?
Smoke and vapor can certainly be an issue. I had to roast outside for several years due to insufficient vent hoods and overly sensitive smoke alarms. Currently, I am able to roast under the vent hood at this house but I never do dark roasts and my batch size is 1/2 lb or less. Roasting indoors has definitely been a gamechanger, since I am getting stable temperatures year round, but you are right that it isn't possible in all homes.
How big are your batch sizes and how dark are you going?
What happened between 5:15 and 7:35?
Drop? Tempature? Can you please explaine
Drop is when you end the roast. In a typical drum roaster, the beans will literally "drop" down into the cooling tray. For the home machines I use, it just means when I end the roast and begin the cooling cycle. I've never used temperature probes so I can't comment on any specific temperature data to look at. Listening carefully to how the cracks are progressing will give you all the info you need!
@@JohnDennery I just found your channel.
I'll watch more videos and hope to find the info on the application of heat applied to each stage of the roasting process.
What stage requires what abount of heat. Please reply so we can discuss the finer details of the various methods.
Thank you so very much. I just roasted on a cube shaped roaster over a gas camping stove not 30 minutes ago.
I don't understand the point of weighing to measure moisture loss, because you never know the starting moisture content of the green beans.
The point is to help you determine the level of roast compared to other batches you have roasted of the same beans. If I roast a coffee that loses 13.5% and it tastes amazing, I will try to repeat that again with the next batch. If it seems like a bit lighter or darker would be more to my liking, I will use that as a guide to make my next roast longer or shorter. It really just helps you dial things in!
@@JohnDennery I disagree. To you it may seem to work, but the science doesn't support it.
There’s a third crack, “the charcoal”. tried it once the taste is unbearable😂
Wait, are you serious? I’ve never heard of that. But then again, I desperately avoid 2nd crack at all costs 😂
@@JohnDennery yup im serious..hehe..i messed up my 1st roast..the beans overcooked so it became charcoal then i tried it on espresso it does tastes like charcoal..hahaha

how to roast sustainably ?using renewable energy and only selling to locals to reduce carbon footprint?
That would be an excellent choice. You could also go much deeper and research the farms producing the coffee, the methods they use to ship the coffee, and the packaging it arrives in, etc. This will require a global effort at some point but renewable energy and selling locally will be a powerful way to start!
