@@yuryrushik5598 I roast on a Mill City 500Gram Coffee Roaster millcityroasters.com/ . They are manufactured in China, but engineered by Mill City. The older version like I have is very similar if not identical to the North TJ0-66.
@@VirtualCoffeeLab I heard China made roasters does not have a quality compare with Taiwan or Turkish roasters. Is it true ? .... What is your roaster price ? No any problem with it ?
@@yuryrushik5598 Because Mill City has engineered this machine, the quality is good. They provide great service here in the USA. If you live in another country, I am not sure of availability. You would need to contact Mill City Coffee Roasters to find out where they ship. When I purchased mine, it cost 2,500 dollars US but now they are more expensive (around 5,000). There is another roaster that is very good - the Aillio Bullet - which cost around 2,500 and has a similar capacity but also has some auto modes and is electric, not gas. You will need to research that, I don't have any more info about that.
What a hobby. If I had that machine, my neighbors would drink free coffee. Yesterday, 3.8.2024 I bought some beans and I am going to use my wok to roast my beans.
Thanks for the info Mike. I have two more times to season the roaster then ready to start roasting great coffee. That is great! So far everything I have done on the roaster has been great. I think you will like roasting on it. I will be waiting for your videos to be available, in the meantime Happy Roasting!
Missed your response. Not roasting yet, but really looking to start. I’m a new product development chemist, so I love the science and experimentation aspect of roasting. I used to brew beer but the calories from that endeavor got me a bit plump. Lol.
Thanks for your comment and for watching my video. There is a learning curve to coffee roasting. Don't get discouraged. What are you using to roast your coffee?
@Eduardo Godoy, my roaster is a Mill City 500 gram coffee roaster. I purchased it in the fall of 2017. It has been a great roaster and allows me to roast coffee in almost any profile!
@@VirtualCoffeeLab it looks like if it’s new! It looks like if you just set it up out of the box! It’s immaculate! It’s simply beautiful set up! I looked it up and the new model had gone up in price to about $4,700 if I recall correct! Maybe some day I may consider something like this! But for now let’s see how the Behmor 2000 AB plus works for me when it arrives next week! Thanks!
Thanks for your question Erhard. I am able to understand my parameters for gas and fan based on my past experience (trial and error). If you watch my ideo “3 tips for new home coffee roasters” Break down the total roast into three phases. Each phase is a percentage of the total roast time. Because I know approximately how long it takes for my roaster to dry coffee. I can select a specific temperature to aim for my total dry time. For my roaster, It takes between four and five minutes to dry my coffee. That means I’m probably gonna have a 9 to 10 minute roast. I plan the rest of my phases accordingly. Because I want to avoid roasting defects like scorching and tipping, I want to make sure my gas is not too high. So, are usually set my gas at 80% during dry. Then I turn my gas down when I am approaching dry end two slow down the pace of my roast. Take a look at this video I did. We spend time talking about what church temperature to use and why. th-cam.com/video/OO9nMHvtJ9k/w-d-xo.html. Your question about air is answered in my most recent video “five ways are use air roast coffee”. I hope my answer has been helpful
Hi Lou, the 3 colors represent the 3 phases of roasting. Green is the dry phase, burned yellow is the browning phase and brown is the development stage. While roasting, the graphic does not appear. After you complete the rosy it appears as a visual summary of the rosy phases. Artisan displays the temperatures you mark during the rosy. So, when you reach dry end and tell artisan you have done so, the time and temp are logged and displayed on the roasting curve.
@@VirtualCoffeeLab OK, I don't think I am describing my question very well. I understand what you mean by the roasting phases, and I can see that on the display at 12:51. What I am referring to are the different colors bands that go across the entire width of the display between certain temperatures on the Y-axis. For example, on the display shown at a time of 6:53, there is a light green color that goes across the bottom of the display (with also some white lines) up to about 338 F; above that is sort of a tan color that goes across the display from 338 F to maybe about 350 F; and above that a darker tan color that goes across the display from 350 F up to 450 F. Then there is a white band at the top of the display. Did I do any better with that description?
@@luigicollins3954 gotcha. So those horizontal bands do represent each phase of the roast. Instead of waiting until the end of the roast to see the graph at the top, Artisan allows you to monitor your phases visually with these color bands. Artisan can use the preset phases you select in it's settings or simply follow your marks when you tell it you hit dry during your roast. See this link: artisan-scope.org/docs/phases/ In my case, i am using the auto mode where artisan is marking those and that is why they don't necessarily line up with my temps.
Hey Mike, love your videos! I just bought a new Aillio Bullet, upgraded from my Gene Cafe. I am in the process of seasoning my roaster. Would you have any medium-dark profiles that you would be willing to share with me? I will be trying to roast a Colombian Reserva Del Patron that I will be trying first. Any info would be greatly appreciated.
Hi Lj. Congratulations on your new roaster. That is exciting! I would highly suggest you use the "seasoning process" to understand how your roaster operates, how quickly it takes to get coffee from charge to yellow, and then first crack. This information will help you plan and practice your roasts. I don't have a dark or medium dark profile to share yet but I will soon and will share it with my channel.
Hey Mike, Quick question, I believe in one of your videos you mentioned a percentage to try to stay within with three stages. Drying to yellow stage - 40% Yellow to FC stage - 35% FC to development stage - 25% Am I correct with these stages and percentages?
I think you might be thinking of my video "3 tips for new home coffee roasters." For a drum roaster, depending on the type of roast you want, a great place to start is 50/30/20 with about a 10 minute roast. For darker roasts, you can lengthen your time and your profile might look like this 40/40/20 . You just need to know your drop temperature and charge temp to make that happen.
Hi Vic, thanks for watching my video. You can setup buttons or sliders in artisan. Here is a helpful link to get you started. artisan-scope.org/docs/events/ I've used both and i like the buttons better. If I'm not accurate and fast enough with the slider, it marks a reading that i might now want. So, I use the buttons.
Hi Terry. I'm glad you have enjoyed your Behmor. Just like the Behmor, there is a learning curve with any gas powered drum roaster. I can honestly say that after getting past the initial learning curve on the Mill City roaster, I noticed a pretty big improvement in cup quality compared to the Behmor. I think there are some who might not agree with me and that is fine, but for me, the drum roaster was a game changer. I have roasted some really good coffee using the Behmor and would recommend it to anyone who is considering owning one BUT if you have the opportunity, and want to take your coffee hobby to the next level, I would encourage you to try the drum roaster. The drum roaster forces me to engage the coffee more during the roast process. I am able to smell the coffee and visually inspect the roast using the tryer. I can see when the beans get wrinkled and can more accurately drop my roast exactly when I want. Also, connecting to Artisan provides more engagement in the roasting process. I am able to be more creative with my roasting style as well. Maybe it has to do with the ability to have more control over the temperature, air and drum speed, and then cool the beans quicker. Or maybe it's because I have 10,000 BTU's to help get my roast progressing through the phases. I have flexibility to experiment with drastically different roast profiles that I would never be able to do with a Behmor, allowing me to find a profile that really works for a particular coffee. I hope my answer was helpful. Thanks for your question.
Hi there, I got a little confused about your pre heat process vs your heat up to charge temp. Also could you share the actual settings you used for your roast? The heat, fan etc?
Hi Steven, thanks for watching. Do you have a drum roaster? Aldo you have a phidget? Are you currently connected? Regarding my preheat vs charge, there are differences. That is a great question by the way. So for me, pre-heating my drum roast is to heat up the entire roaster, not just the drum and air. I mean everything. The metal chassis, as well as all the metal parts all are heat sources for your roast. With this in mind, you want your roaster pre-heated to about 10-15 degrees or warmer above your drop temperature. This is really important. If you are not warming up to that temp then your roaster is working harder to provide energy to move your coffee through the roast. Once your roaster gets to your pre-warm temp and stays there for about 20 minutes you are ready to roast. This time can vary depending on your roaster. Now, charge temperature. This is a personal decision. I set up my charge so I am at my target bean temperature BT probe charge temp and my exhaust temp ET is about 40 degrees above that. This allows me to soak my beans for the first 30 seconds to a minute before I turn gas back on. I use the ET temp as my signal when I turn the gas back on. This helps me reach my target dry time at the right time. The ET is like some stores up energy for me. Is this what you were asking about?
@@VirtualCoffeeLab Hi there, thanks for the response and so fast! we had a conversation before about the roaster I ordered. (Yoshan Newest EC-500 Electric 500g Coffee Roaster) and I just received it. it has a touch screen display with artisan like graphing capability. but it is not as configurable. it only works in Celsius unfortunately and it does not have the ability to mark dry end. but it does have bean and exhaust temp and rate of rise and all of that. they say it can also work with artisan, it supports wifi, and usb connections. but I am not sure that Artisan will communicate over usb. so not sure how it would connect. I do not have any phidget or anything. and yes it is a drum roaster. on the questions I had for you about preheating, how do you preheat the whole roaster? without starting a roast? mine has a preheat setting and it sounds an alarm when it hits that temperature, it goes by the bean temp. so if I set it to 160C when the bean temp hits 160C the alarm sounds and then the start button becomes active. it seems the exhaust temp is about 27 degrees higher at that point but yours seems higher. mine starts with heat, fan, and drum all set at level 5 (it has 10 settings on each) you can change it at any time for each individually. I could lower the fan to see if the exhaust temp would go higher? you mentioned that your exhaust temp is what you use to know when to turn it back on, but what level do you get it to, to make that determination. seems like the temp would drop rapidly when you turn off the heat. is that not right? I would be interested in a conversation sometime if your upto that. if not that's cool I understand. thanks again for all of your help.
Hey there, some more information. I was able to get Artisan working. such a big difference. actually it was really easy just had to connect the computer with the roaster via usb. at first artisan would not connect then changed it to com3 and bam connected. set my preheat to 374 degrees then turned the heat to 0 as I hit charge for 30 seconds then turned the heat back to #4 had the fan set to #3 and the drum speed set to #5 hit DE at 4:30 and FC at 8:30 and then dropped at 10:15. looks about right. well see how it tastes in a couple of days.
I just ordered the Yoshan Newest EC-500 Electric 500g Coffee Roaster. It is a full function drum roaster but it is all electric. I wanted the same one you have but they are 6500 now not counting shipping . I think this one will work pretty good. it has good reviews. have you heard anything about this roaster?
Congrats on the new roaster Steven! I have talked with a few people who have the yoshan and they have been pleased. They were gas models, not electric. I’ve looked at the current webpage yoshanroasters.com/products/yoshan-newest-ec-500-electric-500g-coffee-roaster to see more details. It looks pretty sweet. Electric vs. gas is the one area which will be interesting to hear from you one you get a dozen roasts behind you. Is there enough horsepower to get shorter roast times. The webpage says roast times between 5 - 20 minutes. The bullet is electric as well so I think it will be fine. Let me know how it goes!
@@VirtualCoffeeLab this one runs on 220v but only about 12 amps so well see. seems to have good reviews. it does bluetooth and usb so I can use the built in touch screen or also use arisan if I want.
My Mill City runs on 220v as well. I use a stepdown transformer to run it on 110v from my house wall outlet. Not sure if you can do that with yours but you might want to ask unless you already have access to 220.
@@VirtualCoffeeLab 220 is not an issue, I want to ensure it has enough power to roast as well as possible. plus I think if I change it to 120 it will probably increase the amps.
I just got the roaster yesterday, did my first two roasts today. The first one totally got away from me and went all into 2nd crack. It's pretty dark ha. Git some learning to do. So I need to turn down the heat as it gets into first crack? It has no problem doing a roast in a 10 minute window.
It varies based on the size of the drum roaster. My machine, roasting at full capacity is set to rotate about 55-60 rpm. Larger machines might use a lower RPM.
Currently I am using 1 speed. I was using a two step previously where I would turn up the drum speed about 10% just before hitting dry. This gave my ROR a little kick upward before I would start my downward trend.
