    Hi Mal,
    Im no expert but for comfort at extreme roast masses have you considered powering the heating element for heat boost?
    Possibilities may include:
    - manually regulated with a vanilla On/Off switch (0 or 240V).
    or
    - power regulated between 0-100% with the assistance of a Voltage regulating/pulsing device, perhaps something rescued from an obsolete/junker electric stove.

    I would be more comfortable with a little reserve heating capacity rather than flat out and watching the clock and hoping.
    Im not really fussed about it KT, the only time Ive ever tried to roast more than my standard batch size is when I have dregs left behind in several bags that add up to a Kilo or more. 750-800g batches work out perfectly and when the bread-pan is covered, so do the larger batches. With the design of the Big Loaf, running the in situ element is not a great idea as the space between the pan and the BM wall fills up with chaff and would therefore create a fire hazard. A cover is a much simpler and easier option all round really.

    Andy has suggested to me on the topic of preheating the pan that the second roast is always quicker!    Know what he meant?
    Have tried this several times and it makes no real difference with my setup. Compared to the batch of beans, the bread-pan is only a small fraction of the combined mass. Much better to just start roasting from scratch and if Im roasting more than one batch, I cool the bread-pan down between batches so that Im starting from the same temperature every time, i.e. ambient temperature.

    So recently have taken to preheating roast bin prior to a roast, or from another angle,  the double roasts, the first without beans and short the second with beans and and regular elapsed time.
    Kind Regards

    No problems mate.... Best to go with what ever works best for you. I much prefer to commence each roast batch from the same starting point of ambient temperature. Seems to produce much more repeatable results for me....

      Re: Sulawesi Tana Torajah Kalosi bean advice

      I roasted a patch yesterday. The roast was very uneven (any idea how to improve the roast?). However, it tasted so sweet when i ate the bean (yummmm). The sweetness was the first thing that hit my palate. Very interesting~~~ I should let it rest for another 5 days before i cup them. I cant wait ~~~

        If it tastes good Tony then the roast is spot-on..... 8-)

        Beans from this region (and others) tend to roast to a wider range of colours so dont be put off by the colour variation. The proof is in the cup

        Cheers mate,
        Mal.

          Hi Tony

          You might have noticed my first comments here were the roast was inconsistant in colour.

          I did that 2nd roast on the 16/8 and have since tried it , and surprisingly its not too bad at 8 days .....
          One observation is I have had to tighten up my grinder by about 3 or 4 clicks for this bean.

          What was your roast method , profile and quantity ?

            I roasted 300 grams~~

            Preheated my breadmaker to 100 oC then dumped the beans into the breadmaker. Temperture dropped to 51 oC. Than increased 20oC / min until FC. SC came 4 mins after FC.

              Did you get any tipping with this roast ??
              My intention was to approach next roast with this bean a lot slower than first time.

                HS: NA~~I didnt have tipping for my last patch~~Will take your advice next time.

                what is your roasting profile?

                  Hi Tony

                  My second roast was Ok but Ill be running it even slower next time ..... it went like this
                  3 min to 60*
                  6 min 105*
                  7 min 120
                  8 min 140
                  9 min 160
                  10min 175
                  11..... 185
                  12..... 195 ....... FC 198* @ 12-25
                  13......199
                  14......202
                  15.....205
                  16.....210
                  17.....213.........SC 214@ 17-45
                  Pulled it @ 18-10

                  Next batch will be a bit slower between 120 and 190 .... probably just stick to 15*/min

                  Let me know how you get on ...!!!

                    Re: Sulawesi Tana Torajah Kalosi bean advice

                    Got my Sulawesi Tana a week ago and typically, just went straight for the roasting beast! Got to fc at the nine minute mark, raised the heat gun to ease off the heat then stopped at sc on 15minutes. My bread maker is direct wired so it fairly flings the beans about resulting in this case, an even roast with only the odd slightly lighter bean. End result at about CS9.
                    Tried it today and are impressed, good acidity that goes realy well in milk with a longggg aftertaste. Seems even punchier than the Sulawesi Rante- which I also realy enjoyed.
                    Cant wait to take the advice of this thread and further experiment!

                      Did a roast yesterday to just on first snaps of 2C, bit uneven but expected after reading comments from other roasters.
                      Just cupped it after 24 hours, dry aroma had citrus acidity, broke the crust and a rich choc/winey aroma was apparent, lovely smooth body and rich mouthfeel which got better and better as it cooled down. It has left a pleasant lingering aftertaste on the roof of my mouth, will rest five days now before trying as espresso.

                        Hmmm~~this is a very strange bean to roast. I roasted my 3rd patch yesterday. The roast was very uneven. The strange thing was some of the beans were well roasted, some of them were under roasted. The "well roasted" beans tasted very sweet. However, the "under roasted" bean tasted very earthy~~~ Im just thinking how can i improve next time.

                        To be hornest, it tastes so good when it is well roasted.

                          I have roasted this bean several times. I have found that if I use a very slow ramp up with the heat gun as far away as I can get it with the drill stand. When the temperature drops down I let it get down to about 12deg a min and then try to maintain this until FC. FC usually comes about 13-14 minutes.

                          I then drop the heat back and finish around the 18- 20min. mark just on or at SC. I find this reduces the tipping but you may still get an uneven roast. This gives me a very rounded flavour in the cup with very strong choc aftertaste that makes you want another cup. The roast colour is generally about CS 9 but as I said a very uneven bean to roast. Looks are one thing but the taste of the coffee from this bean is greatm regardless of the uneven roast.

                            Dont worry about the uneven appearance of the roasted bean batch with this variety.... 8-)

                            It does roast quite unevenly but not as unevenly as some. Just let your palate be the guide and go with that. Depending on how you intend brewing the finished result, you can pull the roast before Second Crack(SC) even starts at around CS7-8 for various manual brew methods or allow it to coast gently into SC up to a max. of CS9-10 for espresso.

                            This bean seems to give the home-roaster plenty of options based purely on roast depth alone so try experimenting a bit with this and then see how you like it best. It will still produce an uneven batch colour which ever way you go.....

                              Mal: From my lot, the lighter beans have more sweetness than the darker beans. However, the lighter beans have more earthyness, which i dont really like, than the darker beans. My goal for next time is to maximise the sweetness and minimise the earthyness.

                              P.S: I really like this bean.
