    Re Roasting Beans

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi All

    I have had a storm this afternoon in QLD and has taken out my roaster when the power went out. My question is the roast only got to 80 degrees and the coffee is not even coloured at all . In total it ran for 4 minutes before it got shutdown.

    So would it be reasonable to think I could just start the roast again as it should only have dried the beans slightly really in my mind without really any roast taking place. Not concerned to get rid of them to the chook pen but I hate waste.

    Any information would be great . Cheers

    Should be Ok to try anyway NJD, I would...

    The worst that can happen is that you end up throwing them away after all but I'd be surprised if it came to that.

    I'm thinking the same Dimal. I'm sure they will be okay but yep if not I'll find another use for them. Keep up the roasting advice please , you are a bible mate for us novices out there.

    Cheers

    I’ve actually had this exact scenario on the KKTO. As the beans were still green I recommenced the roast when possible and just adjusted my profile slightly (a little less heat post TP and shaved some time off the total roast length). In the cup there was very little difference to my usual profile for this particular bean!

    Give it a go . Yeah I had my Behmor turn off randomly once midroast, I think it was possibly halfway through or actually might have been just as first crack was happening. Had NO clue what caused it, but I just restarted it when the roaster decided to cooperate and it didn't turn out the exact same as it would, but near good enough still!

    Rule of thumb - less than 100C and all the moisture hasn't left the beans yet and it will make little difference. Some countries (eg: DE) and some of the bigger commercial roasters intentionally double roast like this. Once to remove the moisture, then store the beans and then the following day roast to completion. It's also a commercial "trick" for roasting beans of different moisture contents together.

    Just remember that your second roast will be quicker... don't walk away!

    It's trickier to answer after 100C but I've done it will minimal flavour impact before.

    Cheers all. Thanks Andy and thats interesting that it is actually a practice for some commercial roasters. Sometimes the situations you stumble into are the best learnings and you dont even know it. Will give it another roast today and see how we go.

    Thanks again all

    Just a follow up for anyone thats interested. Re roasted the beans the following day and now have samples a few days later and no issues at all in the cup. As per usual damn delicious with no difference to a normal roast.

    Thanks everyone for the advice

    Cheers

    Behmor Coffee Roaster
    First post and still a newbie to roasting, but I have an older Behmor 1600, not the Plus model and was roasting 1/2 lb of beans and got almost to first crack when the roaster decided to shut off. Tried waiting for it to cool down and start up again. Would not start the roast, I got busy with work and did not have a chance to try it again until the beans had rested for a couple days. Last night I put them back in the roaster and hit start on the 1/2 lb P1 setting and danged if it didn't work all the way through the roast until just after second crack. Let it rest until morning and ground up enough for a pot and it tastes great! Contacted Behmor support and they gave me some things to check. I am the 3rd owner of this one.
