    I have the same BM. I think I just hit the manual button till knead comes up then press start. Goes slow for about 5-10 minutes then fast. Its been doing the job flawlessly for a while now. Nothing like fresh roasted. I reckon its in its prime for only 2 weeks post roast.

    Good to have a wooden spoon handy, not just to visually sample the beans towards the end of roast but also to stir them if the BM ever stops mixing mid roast next time.

    Hi James

    I just took a look at your website and it looks like your roasting is going great .

    I noticed on the 7th May your BM stopped mid roast , and you saw an error message .
    Just in case you havent figured it out yet .... the Breville machines have a heat sensor on the inside. On my machine if I disconected it the thing wouldnt run so I moved it to the other side of the control room ... ie. as far from the heat box as possible. .... never stopped again after that mod .

    Looks like your enjoying your corretto journey...

    Cheers

    2nd roast today. Bolivia Montanas Verde

    Used one of the spreadsheets from right here on CS to try to get some profile happening, didnt do too badly if I do say so myself!

    blogged it here: http://thebeaningoflife.com/2nd-roast-bolivian
    includes PDF of the spreadsheet

    I should also mention, the first roast I did last Sat has really come up nice now! five days on... its really nice today in the cup, yum

    I must be due for a short holiday.
    I sympathise with you Den.

    Preeety difficult to get away for a few days when you have a business to run.

    Heres pedantic, rotating the gun 490 degrees would have the gun pointing in the way if you hung the handle by a hook, nozzle pointing south west, which would burn a nice hole on the console of the breadmaker. ;D ahem...

    If youre keen on the DMM James, have you considered Andys DMM logger and using a pc with the free roasting software.

    I use both a desktop and laptop to store info and to plot roasting progress.

    I recommend that type of kit if youre keen to do it properly.

    Coretto, cooler, pc, DMM, together with scales, diary, wooden spoon for visual sampling, mittens. Done.

    Keep it safe mate.

    What i do with my Bosch heatgun is sticky tape it to the console panel with the nozzle just a tad inside the pan and set it to 490deg. I put beans in when constant mixing occurs. You can preheat the pan at 180 deg celcius during pre-mixing period, then up the heat to 490 once constant mixing starts, then put beans in.

    Id suggest dont use the DMM yet, as you want the simplicity of roasting with a clear mind and less clutter.

    I guess you be drinking lots of coffee til the next time u roast  ;D ;D

    Luckily, I organize coffee for the guys at work at 50c/shot. Work machine, my beans and grinder.

    We go through a fair amount. Maybe 6 a day.

    I pulled a shot of my first roast this morning. It def needs more time to rest. I did only roast it on sat arvo after all. Still, it didnt taste too bad. I had thought I burnt it, but it has some acidity and is a little bright, still the taste is in the middle of the tounge, not bad, but too early to drink for sure. Its not as dark as I thought it was.

    No idea when I will have time to roast again, with two little ones, and working all day, weekends are about as good as it gets.

    Very keen to get the data logger set up, with a display, if only to watch the temp as I change variables.

    A for heat gun, I have it setup on a camera tripod, can move it any direction. I think I might change to an adjustable lamp arm though.

    I think I have the bug hahaha

    For a minute there I thought you were referring to the angle of the heatgun and thinking to myself, "how bloody pedantic."

    I get it now. :-[

    You guys are awesome, so helpful, thanks.

    I picked up an ozito heat gun, it has two speeds and adjustable temp, I started with the temp adjusted to approx half its capacity, next time I will crank it up a fair bit more. Will probably also look at setting up a proper cover so I can partially cover the roast while its under way to retain some heat in there. I am roasting outside, and if its windy, its harder to maintain temps.

    I need to get a probe for my DMM so I can note temps, my current DMM only has bead probes, they will melt in the roast. Waiting for beanbag to get more data logging dmms, I think I would be better off doing this for consistency than trying to guess the variables.

    With the first roast taking so long, Im sure it wont taste that great. I bagged the roast at room temp and will taste on Tues.

    Looking forward to another roast, maybe today if the rain holds off. My wife was pretty mad that I filled the house with smoke and stench. Even though I roasted in the garage!

    Probably my most loved thing so far, is the fact that I can roast 5-600gm batches in one hit. Impressed.

    Could someone point me to detailed photos of a DMM probe installation? Or take some pics of yours and share? Taa

    Hi JamesM
    Prepare to become totally addicted ;D With my first coretto roast (approx 8 months ago) I erred on the side of caution with heat input and consequently dragged the time out quite a bit ....... still thought the roast was great lol. Best of luck on your journey of discovery. You can get plenty of help and advice if you need it from fellow CSs.

    Well done James,

    Next time, start with 490-500deg celcius on the gun.
    First crack should arrive anywhere between 10 minutes to 14 minutes.
    If your gun doesnt have adjustments, find a stand, like a camera tripod ( u can find them in the Quokka paper), a soft drink cap stand or a drill stand and fix your gun to it.

    When start of first crack happens, lower the heat by about 50 deg on the gun setting, or increase the height of the gun if you using a stand. Between first and second you are aiming for a 3 second approx rise a minute on the DMM.
    Have a fan running so that the chaff blows away from the gun, not into it. Low speed. Chaff blocking the inlet can cause problems.

    Note down the time it takes from start to first crack. If it falls below or over the times mentioned, then you can make adjustments to the heat input over time.

    This period of roasting is quite a steep learning curve for anyone starting out on a coretto.

    It;s like cooking. Always good if you can taste the results between your first roast and your second and so forth until you find the right one for u.

    Just did my first roast. It seemed to take forever compared to what others are getting, time wise. I know I should ignore other peoples times, but it goes something like this:

    El Salvador Majeda 13:22pm
    First Crack 17min
    Second Crack 23min
    Temp at 2nd Crack 192c
    Ambient temp 32c

    Temps were taken with an IR temp gun (on the roast), and a DMM for the ambient air temp (because it doesnt have stainless probe)

    I think I might have completely missed 2nd crack, is it usually difficult to hear? 1C was very distinctive.

    I had the heat gun only on about half-temp, 8-min in and very little colour change, I uped it more, to almost full. At around 12 min I put a bit of a cover over the roast (a big floor tile) because it was windy outside. Lol, consistency will be fail! After 1C I took the tile off, and turned the heat gun down a little

    I think next time I will leave the heat gun up high, and have the tile over the roast from the word go. (or do a tin/foil set up).

    The roast looks okay, compared to some other fairly fresh beans I have at home, looks good, pics are in the link below
