One of the roasters I use is the Popper v1 from Sweet Maria's and the way I finish out 1st crack is to start counting when first crack is confirmed and then 10 seconds after hearing the last crack, I roast for an additional 90 seconds before starting the cooling phase. Have had really good luck with a flavorful coffee using that technique.

Hi Paul, thanks for watching. I’m glad you are enjoying these videos!

Mike, this video is SO important, especially for those of us using less expensive roasters. I roast with a Behmor 2000AB+. It's a great roaster for the money and I am now making some very good coffee with it! But two things have become vividly clear to me in my roasting experience: 1) I MUST know the fundamentals of roasting. Not so much about temperatures and timings, but more about what happens to the coffee seed (aka bean) as heat is applied, and the chemical and physical changes it undergoes; and 2) I must primarily rely on my human senses to read the progression of a roast. When I roast with my Behmor, I record temperatures every 30 seconds, but that is only to make some cool looking graphs. I never rely on temperature readout values to control my roasting, since they do not accurately tell bean or even drum temperature. Sidewall chamber temperature is not very useful to me at all. Currently, the only thing I use chamber (B) temperature for is an indication of my pre-heat level. But I rely very heavily on my eyes and nose just like you mentioned, and I use my ears to tell me when first cracking occurs. Maybe every 30 seconds I should be recording bean color and size and roast smell. Not sure how to accurately record smell though :-). I don't mean to be tough on the Behmor or any inexpensive roaster; I am trying to attribute the success of my roasts mostly to my senses and information I have learned.

Hello Lou, great comments. All you have to do is look at the poll i created to see that the majority of home coffee roasters will have to rely on their senses if they want to improve their roasting skills. I'm going to wait a couple of more weeks before I try and process the results but they are very telling. I think one area that home coffee roasters don't think much about is how pre-heating will influence their roast. The other is controlling their heat. But how do they control heat if they have no reliable way to measure it? I've been doing a lot of thinking about that and hope to include my thoughts on a future video. I'm glad you are enjoying great coffee now! You must be getting low on your original order. What are you going to do for greens?

@@VirtualCoffeeLab There are a couple of key things I have learned to do to tame and somewhat better control the Behmor: pre-heating, and using a "Roast Weight" of 1/2-pound. Using pre-heating causes my Drying Phase times to be much shorter and more in line with those of roasters using better equipment. Without pre-heating, it takes a lot longer to get through the Drying Phase. It was not uncommon for me to have Drying Phase times of more than 6 minutes; now they are 4:30 to 5:00. I think pre-heating causes the beans to undergo drying a little more like that of a solid drum roaster. I have pretty much have batch sizes of 300 grams or less, and I always press the 1/2-pound "Roast Weight" button. I used to always select a 1-pound Roast Weight to get the longest possible roast time available, in case I needed it. But the advantage of using 1/2-pound Roast Weight is it causes the afterburner vent to open at a roast time of 5 minutes, instead of at 8:30 when a 1-pound Roast Weight is selected. When the afterburner vent opens, it significantly disturbs the roasting temperature, and I felt it would be better for that to happen earlier on in development, like close to the end of Drying or very early on in Browning. I felt it would make temperatures more stable in the Browning phase, and might possibly provide a more uniform overall development. I had heard of others doing that, and after I started doing it, my roasts have been much easier to control and have come out much better. Anyone thinking of doing this please note, I always press + a bunch of times to get the maximum roast time for a 1/2-pound Roast Weight (which is 13:30). If your roast needs to take longer than 13:30, you will have to use a 1-pound Roast Weight. When I bought my roaster, it came with 8 lbs of a variety of green beans. I have used up most of those, as well as some I bought from a roaster in Grand Rapids. I have a few pounds of green beans left, then I will probably be ordering some from a wish list I have at Sweet Maria's.

I’m in the same boat as you - usually roasting between 200-300 grams, preheating, etc. I’ve found that, especially with roasts with some more development on them (darker side of “medium” prior to second crack), using the 1 lb setting gave me some smoky/carbon flavor, where the 1/2 lb setting tasted cleaner/less smoky. There could be other issues at play, but I think the exhaust/afterburner plays a big role in dissipating the smoke and steam that could impact flavor. Great point Lou!

I’m almost 70 years old and find it difficult to discern subtleties in odor. I believe this to be a fairly common issue as we grow older. I know I love the smell of roasting coffee but find my senses unreliable when roasting in my 3lb drum roaster. Wikipedia has an article on coffee roasting which gives temperatures for the various roast levels like City, Full City, etc, and I use those temps successfully to determine when to drop. This may be helpful to the few that have similar issues with their sense of smell. I’ll try to use your suggestion of smelling every 15 seconds or so and see if this old dog can learn a new trick. 🙂

@VirtualCoffeeLab

2 жыл бұрын

@oldgrumpus, thank you for your message. Not being able to discern subtle changes in smell is unfortunate. Assuming you have a 3K roaster, you then have a tryer to smell. I have found that sometimes it takes a couple of sniffs for me to get the aroma. The heat from the beans doesn't help while sniffing but after a couple of sniffs I can usually get some detailed aromas. I'm in my 50's so I still have a little ways to go before I experience the difficulty of discerning aromas. I'm still learning how to describe what I smell which is a big challenge for me. I think temperature is a great solution but could get a little tricky based on the type of coffee being roasted, at least for me. The best time to really try and sniff out the notes would be just after first crack starts. 15 seconds is a long time to wait to smell just before dropping coffee so I probably didn't explain that very well in my video. I watch my end temp very carefully when I roast and I am on the tryer all the time in that last 15 - 30 seconds of the roast. Are you able to taste notes for brewed coffee? Just curious.

@@VirtualCoffeeLab Yes, my sense of taste is pretty good and taste matters! So no problem there. Maybe this seems counter-intuitive since taste and smell are closely tied. So here is an important question that I have not heard anyone talk about... When smelling the roast, and judging the color, how does that influence when to drop? How can one know it's the right time, the optimal time? Maybe a few seconds more would make a difference that matters... I've seen one person pull samples using the tryer at 15 second intervals and cupping all the samples. I would think that leaving the tryer out of the machine that much could possibly alter the temperature inside the drum enough to make it difficult to accurately duplicate the roast next time.... Just pondering. Maybe too much... :-)

Hello @superlloito thanks for watching my video. It's interesting you describe the aroma's after first crack as vinegar. Could you be a little more specific about what you are asking? I would like to help answer the best I am able but a bit more clarification would he helpful. I will try and answer based on my current understanding of your question. It sounds like you are roasting a bean that has aromas that begin to appear after first crack. It is at this point the bean has broken under pressure as moisture escapes the bean. The bean has reached a point where, although not fully developed, is drinkable and giving off aromas of sweetness and other aromas as the amino acids continue to react to heat. Depending on the origin, varietal, roasting profile and length of time being roasted, these beans will give off aromas that don't always transfer to what we taste BUT give us some very exciting and in many cases, pleasant smells! I hope that was helpful from my layman's experience.

Mike, normally I would recommend putting greens in a pre-heated roaster but I know that there are a few applications like popcorn poppers and some air systems where you might not want to do that. So if you have a drum roaster, you want stable temperatures. Your environment is a little outside the box of "normal" so I guess I would ask the question about your roast profile. How long does it take for your coffee to go from green to yellow ? That dry time phase is an important question because it will more or less make or break you roast.

That video is part of a new series I am working on called the "secret sauce of roasting coffee". The videos are meant to start with basic roasting concepts that can be used for any home coffee roasting enthusiast. You will need to be patient with the Behmor and get some roasts behind you so you can understand how it works. Use the Auto mode for a while and then start to practice roasting manually. Most important. Don't roast an entire pound of coffee per batch. Try and limit your batch size to 8 oz (1/2 pound). This will keep you within a total roast time that should produce some decent coffee.

I’m roasting on a freshroast sr540 with an extension tube. Would your recommendation to have a long dry phase (5 or more minutes) apply to an air roaster like this? My dry phases last 2-3 minutes max but my understanding is that air roasters transfer heat more efficiently than a drum roaster like I see you have. Please help!

@VirtualCoffeeLab

2 жыл бұрын

Hi Daniel, thanks for watching my video. First my disclaimer ;-) I have never roasted on a freshroast. So, your statement about transferring heat more efficiently could be true, I don't know. I think your roaster has the ability to control temperature and air right? If yes, I would allow more time during the dry phase for a couple of reasons. First, this will allow heat to move towards the center of the bean evenly. If you apply too much heat, the outer bean will be brown quicker and you could have an underdeveloped roast. I talked about this on the "why is the dry phase so important" video as well as the "how to roast sweet and flavorful coffee". If you fly through the roast, your roasting the outside of the bean but not all the way through. Second, slowing your dry phase will allow you to control the pace of your roast all the way through the other two phases (browning & development). So, if you heat up your beans too quick during dry, more than likely you will rush through the browning phase too. If you are able, give it a try. Try to have your dry phase last 4-5 minutes. Then have the browning phase last 3:30 till first crack and then do your 1:30-2:00 minute development. I think I heard the freshroast is slow to cool down? Keep that in mind when selecting when to end your roast. I think if you try this profile compared to your faster one, you might get a more flavorful cup. Let me know what happens!

Hey Mike, Do you find the temperature of the room the beans are being roasted in greatly effects the roast? What temperature would you suggest roasting at or would all the suggestions of monitoring sight and smell apply? Is there a guide to roast in various temperatures or adjust as normal rules apply. I'm so eager to roast my next batch. 😋

Generally speaking, the room temperature can affect your roast times. My indoor temps in my roasting environment change about 5-10 degrees throughout the year. This temperature range will not really affect my roasting temps and total roast time. People who roast outside with extreme temperature difference do notice a significant impact on total roast times. Consistency is what is important.

I Magyver'ed a paper funnel. Lastly, every time I grind my kitty waits for me to let him smell the coffee. He puts his nose to the catch cup and sniffs it for maybe 10 seconds.

How much coffee are you roasting per batch? If you can keep your coffee moving at charge, consider a higher charge temp. This will help shorten up the entire roast from 11.5 minutes to about 10 minutes. The Guatemala can handle the heat as long as you keep the coffee moving. i think you will like the result with a little shorter of a roast time using the higher heat. Also, I would wait a day or two before drinking the coffee. Give it a chance to degas a little. Also, the roasting plan will help you with the declining ROR and control.

Hi Paul. Temps are difficult to discuss because they vary based on the type of roaster, bean density, batch size and more. Dry time doesn’t really affect flavor but is reveals the pace of your roast. A better way to determine your charge temp and your dry end temp is to simply use time. How long does it take to dry your beans so the are no longer green? Temps won’t always be the same for your dry phase. Moisture levels and process type can cause your “dry end” event to read different temps. So, what type of roaster do you have? What type of coffee are you roasting? What roast level are you aiming for? Share a little and I might be able to give you a better answer.
