    Gambella Sundried warning for Gene roasters

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    :-[ Very embarassed, but DO NOT ROAST 300G of the Februrary Beanbay Ethiopian Gambella Sundried in the GENE.

    I did it today and the chaff got quite a nice red glow happening, both at the exit vent and in the chaff collector :o Which of course caused panic, as I didnt have anything handy to do a quick fire-safe dump, other than the lawn which would caused a bigger problem in keeping the dogs away. Managed to dump into the sieve about a minute after the "fire" started, no damage except for cremated beans, pride and a smoky bean hopper that a dose of Cafetto and a scrub fixed. :)

    I am still learning the Gene, and after reading the instructions I tried a 200g roast of the Sidamo Koriate (also dry processed) and couldnt hear the cracks, so after consultation with another Gene owner, who always roasts 300g, did that with no problems. However it is now apparent that the Gambella Sundried is a much more chaffy bean, so it didnt work in this instance. Two subsequent 250g roasts went well, stopped at very start of 2nd crack at about 16 min, looks like CS 9-10 and smells like coffee not charcol :)

    I hope this experience helps other Gene owners aviod the same :D It is not one to put on the "Must Do" list

    I havent had a fire like you, but I have noticed that 300g is often just a little too much for the Gene. Last time I tried 300g, the roast was very uneven. So now I limit my roasts to 250g and have had no problems.

    Last week I roasted 250g of Sidamo Koratie and I could actually hear the cracks. Compare with the roast I did tonight with Brazil Bourbon Bold- couldnt hear any cracks and stopped the roast when the desired colour was reached. And when smoke started to pour from the chaff collector!

    Yep, I quite enjoyed my first fire in my gene, keeps you on your toes!
    :D
    If you stick to the line on the roaster (250g) and empty your chaff collector then you wont get any fires.

    Wow. :o

    In the 2 years that I have had my GC, I have never had any fire in it....and I always roast in 300 gm batches.

    This has really got me perplexed. :-?

    Just a small question, directed to anyone, do you guys clean the chaff catcher AFTER ever roast that you do?, and this includes the roasting chamber.

    Carryn, I got your PM on this matter.

    Hi all

    I empty the chaff container after a run of about three roasts done in one session - unless its a roast that I know produces lots of chaf or I see lots of chaf while roasting. But if unsure empty it after each roast - its so easy to do this that I suggest you do. I also have found that 300 gms is a bit much for the Gene - my standard batch size is now 250 gms. For a new unknown bean test with 200 gms.

    Roasts that I have found produce lots of chat are Indian Chikmagalur and Brazil Sweet Naturals.

    I would agree with the 250g roast as the better option .
    Would guess from my experiace with this bean though it be only 10 roasts or so , that the flavour would be leaning towards the lighter end off things slightly tarty fruity very light flavour ??
    Have you Tried Cuping it Yet ?
    After doing 3 roasts over 20 min and them being CS9+10 found that the flavour was lacking .. somewhat.. Then with next roast was very carfull to try and hold myself back from stoping roast as I nervously watched oily patches on some off the smaler possibly dryer beans starting to reach max CS10+11 let it run for anouther 20-30sec as i slowly had wound the heat back and then let the standard cooling cycle run for anouther 30 sec befor dumping them i a colinder and fan cooling.
    The overall bean roast looks like a 10+11 and after leting them do there thing in a coffee valved bag for 3-5 days the flavour is ... well the best i have tried to date and mixs very well with all my other beans . Have found i have wound the grind back a few notches with this batch though seems to cup alot better.
    let me know how you went. :-/

    I have definitely been emptying the chaff collector and removing any stray chaff from the chamber after each roast.

    I was thinking that one small bean may have got stuck, causing the chaff to build up, get too hot and ignite, I will keep to smaller roasts for this type of bean.

    My cupping language and palate need a lot of work, I cant identify and label many flavours, but very nice as a half and half (short long black), Im not up to full shorts yet. Not quite enough body for me in milk. *Ill go a bit darker next roast and see what I think :)
