I plead insophistication when it comes to coffee roasting. I have a Behmor and I'm still trying to make since of the profiles. I was trying to just get to the first part of the 2nd crack on a bolivian bean. I used profile A, 1/2 lb,and added 45 seconds (I think I saw that in one of the posts). Well, between the smoke alarm, the Behmor and the stove fan, I pretty much overshot it. Wasn't there an IPOD program to capture the frequency of the beans? I know I saved it so I'll look back and find it. I used profile D on another bean and never did get it to first crack (or just barely) even with adding as much extra time as I could. Could someone explain these profiles either on or off list, or refer me to some archive? I just can't seem to get it right. Also, what is this "fix" that every talks about for the Behmor? Let the new kid in on it. Thanks!

Unless there is something VERY wrong with your Behmor you should have no problems hearing the cracks........... The program was one that (I believe) Pecan Jim posted about..... Best way I have found to get to the darker roast with a Behmor is LIE to it about how much coffee you are using...(weigh out a 1/2 pound and enter it on your pad on the Behmor as a pound).

Mary, If your using a PC, go to www.behmorthing.com and download Ira's BehmorThing program that helps you plan your roasts and track your inventory. Very helpful program. It even reminds you to do the cleaning cycles and maintenance at the suggested intervals. I could even send you my database if you want to look at the profiles I've used, once you've installed it. If your not running a PC, I can dig up a spreadsheet that another Behmor fan wrote and send it out to you. Basically, there's five profiles, four times, and three weights that you program in. The P1 profile is just full power from the start of the roast (once the heat ramps up) to the end, this can be good for large batches and beans you want to take to first crack, but the beans can pick up enough heat momentum that they'll go from first crack to second crack with little separation and they can get roasting so fast that it can be difficult to stop at a degree of roast you desire. The A, B, C, and D buttons program in the total length of the roast in time. The P2 profile is designed to drop the temperature at or near first crack to slow down the roast to keep you from barreling right into second and beyond. The temperature drop is the "second leg" of the roast and the third leg takes it back up to full power to finish the roast (if you haven't already hit cool to stop the roast) Pushing the A, B, C, and D buttons will control where this temperature drop occurs and it's best to use BehmorThing to figure out when this happens. Pushing the + and - buttons will not change the timing of the second leg, just extends the last leg of the roast. You can roast a given bean at your standard load size on a P1 profile and note down where first crack occurs then program a P2 profile so that the temperature drop occurs at or maybe 30 seconds before first crack to utilize this. Note that times will vary depending on the ambient temp, my summer roast profiles are much quicker then my winter roast profiles. The P3 through P5 profiles are profiles that start with lower heat and step up to higher heat legs until the end of the roasts. These work well for general roasting and espresso. As for the bean weights, I normally roast 10 - 13 ounces using a 1# profile. The load size is very important and you'll want to probably roast the same amount each time so that you can get a feel for how long it takes to get to first crack. Most people under-dose their Behmor by several ounces, say roast 6 ounces on a 1/2 pound profile, and it is depending on your voltage. You'll want to avoid extension cords and find an outlet that has the least voltage drop (say the outlet that your washer/dryer are plugged into which is usually run with larger wiring on a dedicated circuit). Here's what Joe Behm recommends for profiles of various beans: P1-2.. all centrals, Peruvian and Colombians P3... Brazilians, Africans, SE Asians, Malabar, Jamaican Blue Mtn and Yauco Selecto P4.. Kona and other low grown island coffeeshttp://coffeegeek.com/forums/coffee/homeroast/403859As for the "fix", if you can't seem to get into second crack and feel that your Behmor isn't hot enough, contact Behmor Technical Support (really your first contact should be to them if you feel you have a problem with your roaster, their support is excellent) and they may provide instructions on a procedure to mitigate this issue. So, which profile (P1 - P5) did you use and what was the weight of the beans? There's lots more, check out the forums for more tips, but I've got to go. Good luck, -Chris On Thu, Apr 8, 2010 at 2:20 AM, Mary Shue wrote: <Snip> Homeroast mailing list Homeroasthttp://www.sweetmariascoffee.com/gallery/main.php?g2_itemIdx20">http://host.sweetmariascoffee.com/mailman/listinfo/homeroast_lists.sweetmariascoffee.comHomeroast community pictures -upload yours!) :http://www.sweetmariascoffee.com/gallery/main.php?g2_itemIdx20 |

hey mary, you will do fine as you move along, there are things to remember that many times you may not think about... how much power is coming into the receptacle where you are using your behmor? are you in a house o apartment? that can change your power at different times during the day. please try to remember that there is NO RIGHT WAY!!! there are some Behmor profiles here on Sweet Maria's also athttp://www.homeroasters.org/php/news.phpand several other places. May I suggest the you forget profiles for the time being. Take 4/5 or 6 ounces of beans and just let the machine roast them for you. I think once you see, smell and hear what happens you will understand the idea of profiling. Frankly with all of the machines I have had I "self profile" see um, smell um and dump um!! enjoy your Behmor, great machine. ginny please feel free to email me off list with any other questions? how long have you been roasting. where do you roast?

Hello, Mary in A2 [? as in Alaska in the list of US States?] As a "Ham," I ran A1 and A3 modulation, Never A2. The only popular fix for the Behmor seems to be the drum with smaller holes so that small [peaberry, etc] beans don't fall through. I think you might take care of it with some hardware store stainless steel screen mesh lining the interior of the drum. Might work on the exterior if you attach it tightly with copper, brass or iron wire ties. From same hardware store. Cheers, Mabuhay -RayO, aka Opa! Got Grinder?

Mary I suspect the 'fix' you mentioned is the "bending the sheet metal with a screw driver adjustment" which allows the Behmor to roast hotter - gets to 2nd crack easier.. (It's a simple, easy fix.) I still have the image file and instructions Joe Behm sent, if you want it.

Robert: I think your understanding is incorrect, if I understand what you wrote. There was a detailed thread on the CoffeeGeek forum about this. My current understanding is that the + and - buttons only affect the length of the 3rd leg, regardless if they're pushed before or after the roast is started. Chris or Ira - is my understanding correct? I recall that you were involved to some extent on that CG thread. So that's what I've been following since I read the CG thread. Greg |

Robert: Here is what Joe Behm stated about this topic after discussing it with his engineers in China: I have just returned from Asia along with Central America and while in Asia I witnessed testing, conferred with engineers, and have indeed confirmed the only way to adjust the full profiles, prior to start, is to press either A, B. C or D. In both the prestart or post start mode, +/- will NOT alter anything except the final leg.

I confirmed by testing on my Behmor while monitoring the temperature that the + and - buttons only affect the last leg of the profile both when entered before hitting start and afterwards. Joe Behm has since updated the manual and the latest version can be found on www.behmor.com. Ira has also update BehmorThing to reflect this so that profiles entered in BehmorThing will match what the roaster does. Personally, I was never a big user of the + and - buttons to adjust the start of the P2 temp drop, but I have used a pre-roast of up to two minutes (load the beans and start a P1 profile then stop the roast before two minutes*, quickly program your P2 profile and hit start to continue) when I was roasting a large batch where I needed the P2 temp drop to be pushed out past what was available in the A, B, and C timings. BehmorThing has logic to track pre-roasts and makes this easy. Nowadays, I usually roast a batch size (10 - 13 oz) that doesn't require pre-roasting. The most effective way to control your roasts is by tuning your batch size (as with other roasters). I've got about 125 roasts on my refurb Behmor and am still very happy with it. The family loves the roasted almonds. -Chris *A pre-roast exceeding two minutes (and even less with some roasters) can cause the roaster to heat to a temperature that will not allow you to re-start the roast using this procedure.
