Roasting light coffee on the Gene Cafe has always been something not associated with this roaster. In today's video we talk about the challenges home coffee roaster people have with whatever type of coffee roasting machine they might be using. Each machine seems to have limitations of what typr of roast they are good at. We talk about how to get creative with our roasters to achieve our roasting goals. What type of questions do you have about home coffee roasting. Roasting light coffee on the Gene Cafe is possible and can produce some wonderful results.
Thank you to the Captains Coffee for letting me borrow his roaster and for donating some delicious Honduran coffee to roast and enjoy!

I just lifted the hood off my six years old Gene CBR-101 to do a visual inspection, and some cleaning. The machine measures temperature in the air flow. There is one sensor in the heater outlet (to the right), and one in the exhaust channel (to the left). I don't know how the two measurements are weighted, but it is clear that the actual bean temperature is not measured directly. Maybe it can be estimated from the difference between the left-right readings. The heater is either on or off. The fan is always running, at constant speed I believe. It spins up a little during the cooling phase though. So when you drop the temperature with the red knob, the heater goes off almost instantly. The air temperature drops only seconds later. What the temperature is inside the beans, and how quick it drops, we can only guess. To get a quick view of the parts I mentioned, check out images of the spare parts. It seems that most parts of the Gene can be replaced, which is nice.

GREAT job Mike! Of all the attempts I've seen at light roasting on the Gene, this might be the best one I've seen! You nailed it in your intro: all roasters can do pretty much anything well, you just need to make some accommodations if you want to push the boundaries. You've provided an awesome sample profile here and I can't wait to experiment with it when we get our Gene Cafe back from you 🤣🤣. Don't rush, though, I want to see what else you can do with it! Quick note on the coffee: we've been roasting a lot of anaerobics lately and across the board they benefit SO MUCH from a lengthy rest time. They are tasting ok to great at about a week post roast, then suddenly at around 14 days they just blossom like a flower! Glad you liked this Honduras, it's been one of my favorites since we got it in 🥰

Awhile back I asked you to try a Gene Cafe so we could benefit from your roasting expertise using this machine. I was tickled when you released your last episode with this machine. This episode is even better. It's such fun to see this machine in your hands because you have such an understanding of the process. For example, taking on a light roast and understanding the need to reduce the amount of beans in the batch, for starters. Your explanation of not only the "hows" but also the "whys" so enhances our understanding. Thanks for all of that. Side note: I believe the temp fluctuations you are seeing with this machine are simply the way the heating elements switch on and off. Search the web and you will find mods that have been used to work around this...mainly from the UK, I believe. (Yet another rabbit hole to explore ;)).

Hey Mike!!! Guess what? You know ive been having trouble with my roaster. Yesterday i took a bunch of the bad beans i pull before roasting and i practiced without the stress of wasting my good coffee. I feel i have been scared to use lower heat because in my mind if i use higher heat i know ill hit 1st crack. Using medium heat the beans came out beautifully. I cant drink it because i pulled the beans due to mold and other defects but it looks great. I started with a lower charge temp, like you suggested. I also apllied heat right away instead of very slowly creeping up. Ill try with my good beans soon. The coffee in this video seems like something i would love. Honduran with fruity flavors. Very nice. Thanks man, i feel good again. The frustration has left me. 😊

Nice. Glad that worked for you. Correct, don’t do a soak with the cube. Figure out a way to measure your heat settings. You said “medium” but see if you can create markings on tape or something with more specific increments like “two notches above medium” and then use those as references in your recipe.

My speciality beans are uneven and ugly. I tried to use the same heat application all 3 times. Maybe just maybe, these beans are like the Miramar beans I had a couple weeks ago. I believe those were dried out too much or not enough. Idk... I try so damn hard and I get frustrated and upset. You know my situation and buying great coffee is a luxury so I feel upset when I fail to roast well. I'm going to take a step back for a bit and come back when my head is clear. I'll see if I can send you a few pictures Have a great rest of the week. Take it easy my friend.

Hey Mike, interesting video, especially to give me a new way to look at roasting with the Gene Cafe. On the heating element, last week I did an experiment with an IR thermometer: in the heating phase it was a lot behind the GeneCafe measurements, but in the cooling phase it quickly became spot on, as in the same exact measurement between what Gene Cafe tells me, and what IR sensor says about external cassette temperature. In my interpretation, this implies that when heat element is off, what GeneCafe reports as temperature is a good proxy for the temperature inside of the cassette. I have now done a one off experiment with halting my roast mid roast and opening the cassette to get an IR measurement of the beans and that was 'only' 10 degrees higher than the externally measured cassette temperature. So there you go, you could probably quickly turn the temperature down, let the heating element switch of and get a better bean temperature measurement if you feel lost in your roast :)

@jlantz3691 Жыл бұрын

Hi Mike. Really appreciate the way you emphasize principles (phase %, events, roast plan, color, etc) that are applicable to any roaster. I usually adjust weight based on the way the bean was processed. Dry and honey create more chaff, so I normally reduce the weight slightly. Do you think the reason you had temp variation was because of the reduced weight of this roast? Did you experience as large a variation when you roasted more bean weight last time?

@VirtualCoffeeLab Жыл бұрын

I’m glad you appreciate the principles I share that apply to almost any roaster J. I intentionally do this. Although the title says “Gene Cafe”, it could really have almost any roaster name in the title. As far as charge weight goes, processing is one variable that might cause me to adjust my weight. Mostly it is the profile requirements. There would be no way for the Gene Cafe to do a light roast done right in 9:30 at a half pound of beans. Especially since I used a lower charge temp than in my previous video by 100 degree. The temp variation seems to be to be caused by the roaster heating element turns off when it reaches the target temp and then turns back on after a period of time or a degree decrease from target temp. Not sure which. I think more bean mass would cause the speed decline rate of the temp decreases a little slower but still A 20 degree difference. It would go down 20 degrees in 15 seconds and then go back up in 15 seconds. I think you can see it in the video. Thanks for your comments and for watching.

Hey Mike, great video I’ll definitely try it. I have noticed that changing weight makes much more of an impact than heat. I thought of doing this to do a light roast but I wasn’t sure how much to reduce my temperature, this video will give me a great guide. I tried the profile of your last video and got similar results, I was able to pick up fruity notes but was slightly muted and had a little more roast flavour than I would have wanted. It was great nonetheless and I am excited to try this. Thanks again and keep up the good work!

@VirtualCoffeeLab Жыл бұрын

Thanks for watching and your comments Naif. I'm glad it was helpful. Yea, charge weight has a huge impact on the roast performance. Because there are fewer room temperature beans, the roaster can increase temps quicker. There is also less mass in the bean pile of room temperature beans touching each-other. That is a good thing for performance BUT it is also a challenge on some roasting machines because it is harder to slow down the roast later in the roast. Not with the Gene Cafe. It seems to be able to cool quickly. The other consideration as you mention was charge temperature. I chose that temp based on the bean size, density and process type. I wanted to target a 5 minute dry time. So, if you do a roast trying to follow my recipe, the charge temp may need to be increased or decreased based on what time you find yourself getting to the dry end event. Let me know how it goes.

This is the first time I was able to go this light without having an underdeveloped taste. I this this will work great with an Ethiopian or a fruity washed coffee. I will order some soon and try this again.

@VirtualCoffeeLab Жыл бұрын

ok so based on your times, you would need a little more heat during the dry phase, and a little less head during the middle phase which would give you more time to get to first crack. Did you lower your heat during this roast? Possible your brazil beans are lower density and they tend to take move quicker once the heat has penetrated the bean. How does it taste? It may be "tart" tasting based on your times but i'm curious to see how it turned out.

@naif6821 Жыл бұрын

@@VirtualCoffeeLab Yeah definitely need to adjust my heat for the dry phase and middle phase. I started at 198c ~388f target for 3:20 minutes then switched to full heat until 10 seconds into FC then reduced my heat to 226c ~ 438f till the end. There’s some tart/pungent flavour but not overpowering, still a smooth cup with hints of tobacco and cinnamon. These beans aren’t the best quality they are low density ~1000 masl natural Brazil Rio Minas, pretty cheap I bought a couple of kilos to practice on my gene as it was a new machine to me, unfortunately I ran out of the good beans so I have to wait for a new order. My best roast with these beans was 226g green beans > preheat 250 for a few minutes > put the beans in at target temp of 205c for 2:45 minutes > 245c till FC > 231c till end giving me dry 5:15 55% FC 7:47 26.5% end 9:12 18% development 15.4% weight loss 14.2 with 194g end weight. Very tasty in milk based drinks but lacking flavour in filter/french press. In addition, the colour was more medium than light. Overall, the tart roast had some flaws and lacked flavour in milk based drinks but was flavourful when using a v60, the medium roast was the exact opposite. It really showed me how much a roaster can influence the end result. I apologise for the long comment but wanted to share my experience with you as I am a big fan of your content and learned very much from your channel.

@VirtualCoffeeLab Жыл бұрын

Comments are really helpful as they help fatten up the conversation and explain what happened in th roast. Yep, those tart pungent notes are most likely because you rushed the browning/miallard phase. If you would have gone longer, the tart pungent would have morphed into a more plesant acidity like citrus or whatever those beans are capable of.

My GC stays within 7-8 degrees of the setpoint as it cycles the heating element with the cover down. I would like to get a 240 VAC model. That is really the problem with ALL electric home roasters in the USA--coffee roasters require a lot of power for heat. 120 VAC @ 15 amps is just baby getting the beer. When I first got mine, I couldn't help but notice that the GC did twice as much beans in twice the time of my old Fresh Roast. I have to reduce the charge weight to that of the FR in order to get a good light roast--around 120 grams. I can get a very good city/+ roast with 210g of washed beans to first crack in 10 minutes. So yes, absolutely the only way to get a good light roast with this machine is to back off on charge weight.

I have used a Gene Cafe for years and roasted some amazing 5-6 bean roasts. My later experience was each bean type roasted individually. I think temp fluctuation was do to moisture expulsion/evaporation. Love this roaster as it is amazingly even, you just never know actual bean temp. Found a local roaster, Rimini in SLC, that has an incredible light roast offering. Baldoria & Purugia are my favorites. Gene Cafe is a worthy machine but it is a small batch roaster. You have to study what's going on and observe. Try... and learn pay off.

@slam854 Жыл бұрын

I was a batch Pig and loaded the machine with 240g of each bean type. At those volumes this machine cools slowly. I would do my roast at 3 temps and when done, emerg stop and dump beans into a colander with a fan below. Bean temps came down quickly that way with agitation to prevent carry over. A secret from Evergood is to use 8-10% by weight fermented Brazilian coffee. This unlocks favors in the other beans which you do not taste without this.

Ken, are you having the same difficulty with every coffee? I have found that some coffee is hard to hear but most of them are clear. As I get older I am noticing that higher frequency sounds are getting more difficult to hear, especially when there is other ambient noise in the room. The Gene Cafe people are using a paper towel tube as a resonator. They place it up against the exhaust vent to listen to crack taking place in the roasting drum. I wonder if a similar concept could be used with the fresh roast? Maybe experiment with the tube up near the base of the glass chamber?

It was very difficult to hear first crack. On my drum roaster I could refer to the temperature as another reference when first crack starts BUT i am not able to use the temperatures to know about when first crack takes place using the Gene Cafe or the Fresh Roast as a precise measurment. Color can sometimes be helpful to determine first crack as well. There is a guy who records the sounds using a microphone up close to the freshroast. I'm wondering if ou can useHave you tried the paper towel tube trick to hear first crack on the Gene Cafe? Place the tube up near the exhaust vent and listen for crack. Don't put it in the direct stream of the hot air or you could burn yourself. Another interesting option. i hope to demo in an upcoming video is using a "Sound Spectrum Analyzer". It is basically an app you can use on your cell phone that displays sounds on a graph and where there are clicks, snaps, etc.. that occur within the other noise, they display on the graph. This could be a visual option for first crack but i have not experimented with it yet. You might want to look into that.

Hi Faniel, Chaff hanging into the bean can be more frequent in washed, lighter roasts. Commercial roasters using a large drum find less of this and also time spent in the stirring/cooling tray promote this chaff to rub off. So, find a way to cause some friction on the beans and see if that helps.

Thanks for watching. That's a tough question. Actually, I am doing a livestream tonight about "which is the best home coffee roaster?". We are going to be focusing on the roasters under 800 dollars like the Gene Cafe, FreshRoast, Behmor, Popper, and Hive. Depending on the criteria used to determine "which is best" really determines the answer. I don't have any experience with the Kaffelogic, but I have watched a roast in person and drank the coffee of a "Link" which has the same mechanical parts as the Kaffelogic, just different software I think. The roast I saw was a medium roast level. I have not seen one do a light roast. If you are looking for automation to do the light roast, the only roaster in the 800 or less is the Behmor. Even that isn't fully automatic. The Bunafr is the roaster to watch when/if it actually comes out. higher capacity, manual or fully automated. That roaster seems do it all. I loved the Gene Cafe for light roasts. It was pretty easy to get the roast I wanted (very light) but I had to sacrifices by roasting a lower charge weight to achieve the light roast. I plan to talk more about that tonight. Sorry I didn't give a definitive answer about what is the best roaster for light roasts. Any of the roasters i listed above can do a light roast with some effort.

The temperature surfs when it hits the target temp. The thermostat turns off the heating element until the temp falls and then switches it back on. The machine cycles through this until you move the target temp. You can modify the machine - Google 'dimmer switch mod' - that will gibe the machine much better control. I live in Ireland, and I had to change out the heater from a 240v to a 230v - this made the machine much more responsive. In the end, I sold on my gene cafe. It was a good starting point but I wanted more control similar to your mill city roaster.

I have been roasting for years: popcorn popper, stir crazy, modded ronco, and now a behmor 1600+. the Behmor is about to go, temp surfing has become so ridiculous that the batches don't even finish. So I am in market for a new roaster. If I am being honest, I am frustrated with the market; I don't see anything I like. Couple reasons: I want a 1lb batch size potential which is why I got Behmor to begin with. I however want a modern roast, light and bright. I agree that knowing your roaster and having a roast plan to manipulate off of the roaster's natural abilities (so to speak) is important. Yet, correct me if I am wrong, an air roaster will still offer an easier (perhaps natural) way to roast light than a drum roaster, right? Tools are tools and we don't pound nails with a screw driver. I am asking strictly from a buying decision standpoint since that is the moment I am personally in. Then whatever I get I will learn so I can use the tool the way I want to use it. I don't know where a stir crazy fits in that regard. A lot of the air roasters are small batch sizes. So coming full circle you now know why I am frustrated. Past that it takes thousands to buy something that does everything I want and I cannot justify it. So, it seems you have multiple roasters and have tried many; do you have advice on the direction I should take? I was thinking low entry like the sweet Marias popper since I am not happy with anything...why pay more for something that falls short? I saw also there seems to be a new Kickstarter that has promise. I could also upgrade to a fresh roast but to not know if the extra hundreds is worth it in comparison to popper? Again my goal is light roasts to medium roasts. I accept begrudgingly that my batch sizes will be low since I can't afford an expensive machine. Anyone with any thoughts?

Hi Todd. I'm sorry you are frustrated with the lack of affordable "larger capacity" coffee roasters. Typically, home roasting involves pretty small batch sizes. Yes, manufacturers like Behmor say their capacity is 1 lb but realistically, as far as performance for a variety of profiles under 12 minutes for 1 lb, it is a stretch (my humble opinion). The fact that you are having power issues will make that roasting time even longer. Hot air roasters will be more affordable than a drum roaster and even hybrid DIY breakmaker/heat gun type roasters are used by some that like DIY or are on a budget. I think the KKTO/stir crazy type home-built roasters might be a good option for you if you are slightly creative and handy at cobbling something together. I'm not comfortable saying an air roaster will offer an easier (perhaps natural) way to roast light than a drum roaster. You would have to explain that idea a bit more for me if you want. Natural, as in no emissions? Anyway, even the light roast statement is something I have not worked through with my SR540 to my satisfaction but I am working on it. I am leary of Kickstarter for roasting coffee. Also, their capacity doesn't seem to fit your need for 1 lb. The popper can do a decent job roasting but the capacity is a factor. Even the fresh roast sr540 is limited. Are there people roasting 1 lb of coffee on the 540? The 800 might handle that but you would need the extension tube. It is a tough one trying to figure this out. You may need to go down the DIY route Todd. I'm not sure my comments were helpful. I do appreciate you watching my video and for sharing your dilema and question and for subscribing to my channel. Let me know what you end up deciding.

@@VirtualCoffeeLab I appreciate your feedback. Natural as in one roaster being more inclined to do something more capably than another...kind of like a fastball getting thrown down the middle in the batters "wheel house." If that makes sense. The reason I struggle is my experience. I went from a modded Ronco showtime drum roaster that hit 450 temp to a behmor that safety shuts off at 330 and is now failing. To be honest, I have never understood how behmor roasts instead of bakes if common roasting rules of thumb put roast temperatures anywhere between 356 and 482. I am sure there is a scientific reason, but I have always thought my roasts on a behmor are too long and the safety feature angers me; it is a stressful roast and I have lost plenty of batches over the years. So, my point is in agreement; if the market demands $500+ on machines that I do not grade highly based on experience than the modded route is the way to go but if I am being honest that is insufficient and frustrating. What is the point of saving money to get great roasts as a home roaster if the minimal entry point for a machine is cost prohibitive? I mean, what is the least expensive 1 pound possible roaster with capability out there and how long would it last? Are we saving money, spending more, or breaking even? I am all for a fun hobby and will find a way to continue, yet I think the roaster market is lacking....big time. Sorry for my rant, you are gracious with your time as I try to understand where I fit inside it all.

Hi Mike Great video on the Gene cafe rooster. Just watched your video that you did on the 6/7/23 at 8:47am. Can you tell me what the phase one graft meant, eg. 5.03, 53%, 55%, -00!10.5 Just want to understand how you came up with those numbers. Thank you for your help, Tim (Australia)

@VirtualCoffeeLab Жыл бұрын

Hi Tim. I entered my target goals for the total roast time, the phase percentages for dry, browning (Maillard), and development before starting my roast using this timer my son is developing. 5:03 is the total time of the dry phase 53% is the dry phase percentage of the total roast 55% was my target dry phase percentage -00:10.5 is how much time from my target dry end event. I was about ten seconds earlier than planned to reach that event.

Can you please do a similar "how to" light roast for the Behmor? I'm a beginner struggling. I can only preheat to 250 before cut-off. And, even when in P5, temp B will automatically hold only up to 320. Then, at 7min exhaust fan, temp A will climb past 320. I cannot seem to get a good light roast and welcome any suggestions you may have. Thanks!

@VirtualCoffeeLab Жыл бұрын

The Behmor is different. It generates heat using the quartz elements. In general you can preheat to 200 if you were doing a lighter load. You should also consider using the 1/2 lb setting so the fan turns on at the 5 minute mark, not the 7 minute that happens when you use the 1 lb setting. Remember, your roast time is going to be shorter since you will be using less coffee. I am assuming you will be roasting in the manual mode. You don't need to go over the 320 temp, although you can after the 5 minute mark using the 1/2 lb setting. Keep in mind you will need to slow your roast down as you approach first crack. If you don't, the middle phase will be too short, especially with the lighter load. I do plan on doing a light roast on the Behmor but it may be a while. Experiment with a lighter load using the 1/2 pound setting. The fan will naturally lower your B temp at 5 minutes so crank up the power about 20 seconds before the 5 minute mark to keep your temps from dropping too much. Then after you get past the fan event, monitor temps and start to move to lower power settings to time your first crack event. Also keep in mind that you don't want to go into first crack too fast. If your cracking is really fast and intense you are going too fast and your roast will be too dark. I realize this is a lot for you since you are new to roasting. I would suggest you watch the playlist "Home Coffee Roasting Essentials" as it covers basic concepts about the things we just talked about. Thanks for your comment and for watching Brooke.

Nice video, I tried but the result was medium roast, not light. What maybe I'm doing wrong? It was a Castillo anaerobic.

@VirtualCoffeeLab 4 ай бұрын

Thanks for watching and for being a subscriber. Not seeing the bean or knowing how old it is, there are a few variables. Regardless, the way to correct this would be by managing your heat. Did you reach first crack around the same time I did? There is a good chance you reached first crack sooner. So, that means you would lower your power a little. Look at your roasting events and compare them to mine. Make adjustments to the heat to match the time of the events (dry, first crack, and drop). If you did reach first crack at the same time, then lower your temperature about 10 degrees f when first crack begins and see if that helps.

Any suggestions for a roast profile for Geisha coffees on the Gene Cafe? Would it be the same as this video?

@VirtualCoffeeLab Жыл бұрын

Like any profile, it all depends on what your goal is for the cup. Light, fruity, sweet, juicy, balanced, darker notes. These points equate to phase times/percentages, total roast time and drop temperature along with moisture loss percentage. Consider these things and then understand how the coffee will respond to heat. Think about density, bean size, process type. With that info you can put a plan together. Was that helpful? I don’t know about your particular coffee details so my suggestion wouldn’t be very helpful. Sorry about that.

If you are looking to drink a variety of coffees at different roast levels then the fresh roast might be a good choice. If you like medium to darker coffee with a roaster that is a little easier to use (in my opinion), the Gene might be a good consideration.

@@VirtualCoffeeLab I am to the point where I just don't know where to invest. I have watched so many videos and price is another thing. This will be for me only. Not many in my family drink coffee and my next door neighbor uses one of those K crap things. I like the idea of being able to play with the machine as you do. In the past months I have learned so much about coffee. Most people have no idea what it takes to make a real cup. I like the learning process. I have even thought about the Kaldi wide with the thermo couples. That would make me have to buy a computer. I am a Mac person and my roasting will be in my shop. Even purchasing a cheap computer would add another $300 or so to the cost. I am going to wait on the Fresh roast 800 and hope I can get one before they sell out again. Watching you video on the Gene, I do not want a machine that takes that long or does not give me any control. You of all people know that being able to control the roasting is what it is all about. Thanks again for reading my comments.

No problem Jerry. I know this can be overwhelming. The fresh roast is a great choice. Take it one step at a time and then as you grow and master the control of the fresh roast you can decide if you want to build on your hobby with a different roaster. For now, just enjoy the journey & challenge.
