    Starting out on Behmor

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hey guys,

    I picked up my Behmor the other day and have tried out a few roasts and have been extremely happy with how the beans have turned out, CS9 or 10s Id say (that said I havent tasted any as yet - going to leave them a few more days). Ive settled on roasting 300g at a time (to end up with ~250g roasted) and have been using 1lb, P2, C as my settings. The ambient temp has varied quite a bit in Sydney the past fews days (resulting in some variances in roasting time) but generally Im reaching first crack after 12:30min and second crack around 7:00min after that (I do open the door slightly ajar once first crack hits).

    Do those times sound about right?

    Also, another newbie question: when you guys talk about 1st crack, how do you measure it? a) The very 1st crack b) When there is a number of cracks in a cluster c) Right towards the of the popping? My times above are with b)...

    So related to my newbie question, when the manual speaks about stopping no more than 10s into second crack, is it 10s into a), b) or c)?

    Thanks all,
    Pete* *

    Re: Starting out on Behmor

    Im no expert but I usually consider first crack and second crack when there are a number of cracks in a cluster, so (b).

    Are you getting 7 minutes between first crack and second crack? - if so this seems a bit long to me. This may be because the P2 profile has a large power drop around the 2/3 mark that may stretching out the roast too long with this weight of beans. If the beans are not to your liking but you want to stick with the P2 profile I would suggest upping your bean weight to 350g or you can always change your profile to say P3 or P4.

    Experiment and have fun!

    Yep 7mins between 1st and 2nd crack. If thats a bit long then maybe I should leave the door closed the whole time... What times should be getting?

    Any input is welcomed.

    Re: Starting out on Behmor

    I would suggest 4-6 max - but usually closer to 4. If you like darker roasts then maybe closer to 5-6. I open the door during first crack (about 100 sec ) then close it when it stops. I usually aim for about 4 min. Trial and error - do the next batch with the door closed and see what results you get. Unless you are roasting every other day it will probably be a while before you find the answers to all your questions :) Take good notes of your times and techniques and then it will be easier to compare roasts and develop the techniques that result in coffee you like.

    Re: Starting out on Behmor

    Thanks Pretzal, some good tips there. For my next roast I will try closing once 1st crack has finished. Then the roast after that I will try leaving it closed the whole time...

    Re: Starting out on Behmor

    I would leave the door closed the same time if it was me. Im doing that with 312g, 1lb/P2/C and I press cool when second crack starts and let if roll through second crack while cooling. Been leaving the door closed the whole time. Nice dark CS12 roasts.

    Re: Starting out on Behmor

    I think Ill keep on opening the door for now. CS12 is probably a bit dark for my tastes. Been getting CS10 which is to my liking...

    Btw, extremely happy with the ease of operation with the Behmor. It doesnt even feel like Im really roasting :)

    I think you need to reduce the time between first and second crack 7 mins is too long. Best way to do that is to keep the door shut.

    Yeh will try leaving the door shut for the whole time next roast. Interestingly, the last roast I did (where I wedged open the door only during 1st crack), the roast times were unchanged from when I would leave the door open from first crack to the end of the roast....

    Re: Starting out on Behmor

    Im just now drinking the Columbian Beans I roasted leaving the door shut the whole time even while cooling and it is a lovely roast - best yet. P2, 1lb, C setting. Pressed cool with around 5 or 6 minutes to go - rolling second crack while cooling. Dark roast but really nice.

    Re: Starting out on Behmor

    I also do about 315g on the 1lb p2 c setting.* I track all my roasts with roasterthing and usually hit 1st crack just as the temp drops.* Then Ill normally get 2nd crack occurring at about 16:40, hit cool immediately, open the door and remove the chaff holder, and point a small pedestal fan in to try and cool the beans quicker.* This usually gives me a batch of CS9 or so but sometimes Ill open at 16:30ish to get more like CS8.

    I consider 1st crack as when you get more than 1 crack a second so usually 5-10 seconds after the very first 1st crack.* For 2nd crack I hit cool as soon as I hear the very first 2nd crack because the heat mass of the beans keeps the beans roasting for a while even after youve stopped the machine.

    For the latest roast, I left the door closed the whole time and time between first crack and second crack was ~3:30. The beans seemed decent, havent actually tasted them yet. This all seems too easy, hit start and let the Behmor do its thing :)

    I read about Roasterthing somewhere before. How accurate are the profiles? I understand there could be differences between how the American Behmor is setup?

    Re: Starting out on Behmor

    I like to keep a log of all my roasts, including times for the start (very first pops), middle (rolling) and end (last pops) of first crack and the start of second crack. I record any continuation of second crack in the cooling cycle.

    Re: Starting out on Behmor

    Hi, Saturday I had my first roast with the demo Behmor and Peru beans I bought off Andy at the MICE.* *;D*
    Thanks Andy.
    It was 225g P1 B with the door closed till cooling finished and resulted in a lovely dark (I dont have a CS card) roast.* Rested for two days.* After getting my grind right I pulled two good looking shots.* My boyfriend and I sat down to try the brew.* VERY HAPPY!* Hopefully I can keep producing roasts as good if not better than this in the future - no pressure... Hope I havent peaked too soon.
    I have to agree, it all seems remarkably simple.* Thrilled with the Behmor 1600 and inspired to go on to greatness!
    Would love to hear from who has an xcel type sreadsheet they would like to share to keep track of roast profiles, favourites (and failures).
    Thanks

    Hi javaQH

    behmor is dead simple as you say, if you havnt looked at it already, you might want to check out behmorthing / roasterthing, it was originally designed with the behmor roaster in mind and can track roasts with times / weight / profiles etc

    the profiles and timings on it may not be 100% accurate as its based on the US spec behmor but they would be pretty close

    The good news is that now you have started the roasting journey it just gets better!

    Keep track of the weights and settings you use and what your "tasting notes" are a week later. You will build a knowledge base that will give you a good starting point for future roasts too.

    A word of warning though... soon you will be roasting for friends, family and work mates who will have some of the best coffee they have ever tried.

    Welcome to the "not so dark side" javaQH.

    Pretty good, but not sure what you mean by "profit", I think you mean cost savings? Youve factored in the weight loss in roasting from green but no overheads allocated like electricity, albeit it would be minor, and if you are including total costs it should include the cost of a valve bags (if you use them which I do). No doubt we save money by roasting our own though. Yes theres the labour and time part but most of us dont think of it as work but fun! ;)

    How does Spjarli #4 roast and whats it like in the cup? :)

    Its only calculating profit on the cost of goods, not net operating profit!

    Oops, I didnt mean to share my blend names...

    Truth be told, I havent yet blended the #4 blend, I am doing this post-roast and it still needs a couple more days to rest.
