    Its all happening too early

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi fellow roasters.

    Im consistently hitting 1st and 2nd crack 10 degrees to early. 1st rolls on at 185degrees / 10 mins and Im well into 2nd crack by 212 degrees / 12 mins. I cant seem to get it to slow down to the 195 / 222 goal. Can any one offer any advice or point me in the right thread direction?

    Thanks.

    H Mike
    Going to ask how you got on today!
    I wouldnt worry too much - still got the expected first crack-second crack spread of 20 deg or so. Might read differently on your DMM than others, but Id just adjust your degree expectations to suit your setup.
    So drop you gun temp (more than you are currently) 5 degrees or so before your roast reaches first crack (so @ 180deg or so) and try and stretch out the time to second crack to about 5 mins - even if it ends up happening at 212 measured. The temp is just a guage - first crack & second crack are the important bits to log consistently…

    But more importantly - how have the last few batches tasted?* :)

    dont worry about the temp vs first crack and second crack

    different beans would react differently
    different amount of beans would react differently
    different ambient conditions would react differently

    there are a heap of factors that would cause that
