    Re: Sour beans for a newbie roaster :-(

    Hey Brett,

    Yeah, I know I need to let them degas, but I was way too excited and wanted to find out how they would taste.

    Its interesting to note that my B&D popper takes so long. Will see how I go with it roasting the other bean varieties from my starter kit. Ill do the Indian Tiger mountain next and post the results.

    Cant wait to try them again in a couple of days and see how they fare.

      How large was that batch javabeen?

      My Crazy Popper also does the 5 minute sprint (however Ive been rectifying that - see the Crazy Popper thread).

      I got some Peaberry in my starter pack and tried it out as my first roast.
      My wife likes it (and shes a black coffee drinker).
      She says its milder than the bought beans I started with.

      I like it too in my milk based coffees.

        TG, batch was 80grams. After roasting it weighed in at 70 grams, a loss of 10grams or 12.5%.
        80 grams seems to be OK in my B&D popper as the beans move on their own right from the start so I dont need to stir them - I just like to watch.

        When you roasted the Peaberry, when did you pull it from the popper, before/after 2nd crack? Info please.

          javabeen, it appears you have a nice ripper of a fan in your popper... now, get a chimney and increase the batch to 130g.. see how long it takes...

          I now see that all new poppers have a weaker fan - inc the crazy popper... Must have bought mine before the new ones got released thank God...

          Be interested to see your results with a bigger batch...

          Oh, and I generally take the PNG PB into 2nd...

            Marc,

            Hmm, Im using a chimney already...I will try increasing the batch size as the Peaberry seems to move easily with an 80gram batch so maaybe it can handle more?

            Re: the fan. when I stick my head over the chimney, you can actually feel quite a lot of air coming out so it appears to be quite powerful.

            Now interested to see how it goes with larger batches. Im guessing Larger batch (more beans) means more heat and therefore faster roast times? Is this a good thing or a bad thing?

            Javabeen.

              Javabeen,

              if you can roast 130-150 gms in a 7-9 min range.. thats great and is exceptable... this is what Im getting...

                You dont have to worry about the beans not moving at first. Once they lose their moisture, the fan throws them around pretty good. Push the envelope of the thermal cutoff, then back off about 10-15g.

                  OK thanks Marc/Nunu.

                  Notes taken and will apply to the next roast batch.

                  Do you cover the chimney at all to play around with the temperature?

                        Re: Sour beans for a newbie roaster :-(

                        So, when you cover it Im guessing its to get more temp through the beans?

                        The ambient temp was colder on the night I did a coffee roast compared to the sacrificial roast and you can see from the times it took longer to get to 1st and 2nd cracks.

                        OK so Ive got a temp probe in there as I roast, can anyone share some knowledge on what temps I should be looking for?

                        Javabeen - getting excited...

                          Saw on the news that it snowed in Ballarat.

                          Id suggest only covering the chimney when its cold. However, you want extended roasts, so leaving it uncovered is probably a better idea.

                          Temperature isnt really an issue when it comes to poppers. The issue is keeping the roasts times at an acceptible level during all ambient conditions. That way you at least get some consistency. Poppers are great for beginners, because theyre basically hands-free. For more control over the roast you can either mod the popper to death, or move on to a more control-friendly roast method, i.e. correto, etc.

                            I lose approx. 15%.

                            I pulled it about 10 seconds into 2nd crack the first time.

                            Ive been experimenting with someones suggestion to roast one batch to 2nd or less and the other batch into 2nd and then use them as a 50/50 blend.
                            The lighter half for the subtle flavours of the bean and the darker half for the chocolatey flavours.

                            Seems to work nicely.

                              This is the basis of SO blends. You take a SO, roast a batch just prior to 2nd crack, and a batch at about rolling 2nd crack. You post-blend them, and voila! SO blend. Its not very good with beans that have little body.

                                OK another update.

                                Went out last night in the FREEZING cold at 8:45pm to roast my 2nd batch of coffee beans, a larger batch this time.

                                I roasted 130g of Peaberry 2006. Ambient temp in the roast house was 11 degrees. Beans did not start to move in the popper till after 2mins. 1st crack at 2mins and continued on till around 7mins.
                                2nd crack at 8m40s, I pulled the roast at 9m28sec and they beans looked sensational. I took some pics of them and Ill post them later. They are now degassing.
                                With the temp probe in, I noticed that the temperature was higher with the larger batch of beans, got to around 228 degrees compared to 215 with the smaller batch.

                                This morning, I tried the 1st batch of beans I roasted a day and a half ago and they were very sweet and fruity.

                                Now I cant wait till the 2nd batch I roasted last night have degassed so I can try them out.

                                I think its now time to move on to the other bean varieties in my started pack now that I have learnt to roast coffee beans.

                                Big thanks to everyone for their help and input.

                                Javabeen.
