    Re-Roasting

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Accidently hit the eject on the hoptop today while roasting some Kenyan Dorman A. >:( gggrrrrrr

    was about CS5.

    After it cooled I put it back in and re-roasted it to CS9, what I wanted in the first place. Not many cracks but a few 1st and fewer 2nd cracks.

    Question is, will this affect the taste and how so?
    I assume it will but what should I be tasting different?

    Hey Ronin,

    Join the Hottop wrong button club ::) ::) ::)

    I know how easy it is to do when the eject button glows green :-/ :-/

    I think all Hottop owners would have done this at least once or more ;)

    I put the beans back in ( cant remember what they were )

    They tasted good :)

    Warren.

    Re: Re-Roasting

    Hahahahah ive done it too ::)

    I was roasting PNG Kimel Peaberry and accidently hit the eject button when i thought i was turning the fan up I had a laugh

    It ejected at around CS5 like yours but i kept mine as hot as possible whilst i cooled the Hottop back down to roasting temp again.
    Put them back in and just treated the roast like it had been going for 5 minutes or so and just ramped it up to 1st crack without any delay.
    The result?...Not as bad as expected. Not a lot of aroma when ground but the extractions were much the same. Problem for me was that i was using them on my brother setup(EM6910 and EM480).
    I imagine if i was using it on my setup that it would have lacked body and would have been a bit flat...It might have just been my brothers setup but thats the impression i got anyway.

    Since you cooled your beans down before re-roasting them i imagine you may have baked some % of your roast....

    The taste test will be the proof in the pudding ;)

    Re: Re-Roasting

    Had to do a double roast myself due to pulling the beans out too early. Pretty ordinary coffee, and got worse after about 7 days. Ended up chucking them, but it was worth trying just in case it turned out well. as far as I know a lot of instant and high-output commercial stuff (massive exporters) is double roasted, and the action of doing it means you lose all the undertones in the roast. Still better than an instant mind you...

    Ive done this too, but only made compost!
    Answer - put a button over the eject button with sticky tape, suspended from above. Still easy to eject when you intend to!

    Re: Re-Roasting

    Well I tried it yesterday.
    Ground aroma was prommising.
    Shot looked great.
    The taste was poor. I got some of the flavours the Kenyans have but the bitter/baked flavour finish was overpowering all else.
    I had a bitter taste in my mouth for ages.

    I didnt even bother last time my beans got dumped too early, the smell of my reroasted beans was ghastly , the ground sample even worse. To the bin they went >:(

    Re: Re-Roasting

    had the breaker trip on my multi board yesterday when doing a 600gr roast of Tanzinean Peaberry in the corretto, it was about 8 min in, just at the start of first crack (few snaps). Took me about 40 - 60 seconds to realise what had gone wrong. Started it back up again and took them just into 2nd

    If it wasnt such a big batch, I would have binned them, but just couldnt bring myself to do it.

    Proof will be in the cup I guess. :fingers crossed:

    Re: Re-Roasting

    I have since heard that some roasters like this on purpose, as long as its reached first crack.

    Some for flavour, some for shelf life.

    Imust admit after hearing this I left the roast in question until about day 15 and tried it. It had improved, but not so much that made it good to drink.

    Behmor Coffee Roaster
    Dont know if your aware or not but Turkish/Greek coffee is roasted to just on 1st crack.
    Some instant coffee doesnt even reach 1st crack before being ejected in under 5 minutes.
