  • First + Second try roasting. 1C and 2C very late.

    Hi guys,
    First time poster and first time roaster here  ;D
    Ive been a long time reader on this forum but I have finally taken the plunge in terms of home roasting because of the reported happiness it seems to bring to all home roasters.

    My setup is a little strange because Ive tried to keep my roasting experience low cost, and also hands on to maximise the fun. I use a Heat Gun on a cast iron wok, with a wok turner to toss the beans.

    With the 2 batches I have roasted (500g) batches; one being a PNG and the other a Columbian I got from BeanBay; and they have both tasted really good. The first one was a little light on the roast but the second one was pretty good. They both exhibit the characteristics I expect of the region with nice subtle flavors as well.

    The way I do it, I keep the heat gun about 2-3cm away from the beans and toss the beans around gently throughout the roast. I start off the heatgun at 300 degrees for about 4 minutes then pump it up to 600 degrees for the remainder of the roast.

    My process makes a lot of noise as metal clangs on metal so I dont even hear the 1C so I dont know what time it happens. But 2C is evident and usually starts around 45 minutes into the roast and settles down around 50 minutes into the roast.

    In my opinion, Im pretty happy about the taste of the roasts but I was wondering if there are any issues with having such a long roast time? I dont really understand the reasoning behind having the ballpark targets of roast timings.

    thanks for any input you guys can provide.

    P.S.: Ive attached a few photos too!

    hmm, try to get a stand for your heat gun.
    id say that would be the first step if you are just holding it with your arm lol

    you could probably fashion one up with scraps of material and some duct tape to keep your cost down

      Thank lemoo for the advice.

      Ill build a stand of some sort once I cant be bothered holding it anymore (for now the excitement of roasting still keeps my hands from tiring)

        2 things spring to mind.

        Roast in smaller batches.

        Make a lid. A round saucepan lid, remove the central handle, holesaw a hole big enough to fit the nozzle of the heatgun through, and hold it in place with a hose clamp.

        But if youre gonna go to Vinnies/Salvos to scrounge a saucepan lid, see if you can score a suitable breadmaker (search on here for Coretto). I scored the one Im using for $15.

          Are you sure its 2nd crack youre hearing and not 1st? 1st crack is normally significantly louder than 2nd crack.

          It sounds like youre baking the beans rather than roasting them. Try aiming for a total roast time of 15-20 minutes, 25 at the outside. With the long roasting times like youre talking about the beans will taste flat compared to ones roasted in 20 minutes.

          Given your method you probably wont be able to achieve the shorter times. Using a heat gun with the beans in a wok most of the wok is cold which sucks the heat out of the beans so the beans are constantly going through a heating/cooling cycle as they move in and out of the hot air stream from the heat gun. To achieve the best flavor the beans need to be constantly increasing in temp with no cooling off during the roast. Using a wok (Especially a large cast iron one.) with a heat gun as your heat source it will be virtually impossible to maintain an even and constantly increasing temperature through-out the bean mass. The larger the bean mass the harder it will be. If you want to stick with your current setup try decreasing the bean mass until you reach a point where the roast can finish in that 20 minute time frame. If you want to stick with the larger bean quantities an option would be to put a burner under the wok to heat it. If you have a big enough burner you could probably even do away with the heat gun.

          I would second Commandas comment to go the breadmaker (Called a Corretto on here in honor of the user who came up with the method.) route. You can maintain your large batch size and have a much more controllable and timely roast.

            Thanks for the advice Javaphile!
            I get what you mean about the wok sucking up all the heat.
            Ill experiment with it another time but if I cant get it in the ballpark maybe Ill look for a breadmaker

            Im not 100% sure Im hearing 2nd crack but I always thought second crack sounded like pop corn popping... and thats what I hear 40+ minutes in..

              Hi Pernguin,

              10 Points for effort holding the heat gun that long, i tried a few ways before i found a really cheap bread maker. I constructed a makeshift stand to hold the heat gun. The beans turn out pretty good.

              Good luck with whatever way you go, but i would suggest getting a bread maker

                Look at classifieds for a second hand bread maker and get started with a corretto setup. 40 mins roast and the roast color is still around cs8 Id say its baked. A 500g roast as a first timer is risky so Id keep it to smaller batches to minimize the risk of a bad roast. Maybe even try a target popper and taste the difference between a baked roast and one thats not baked.

                  That sounds more like first crack. Second crack sounds more like Rice Crispies or the crinkling of Saran Wrap when wadded up. In a typical roast at 1st crack the beans change from a light golden brown to a medium brown. At 2nd crack the smoke coming off the beans will dramatically increase and their color will head towards black. These color changes may not correspond to your roasts as its very likely that the outside of your beans are being baked in the direct blast of the heat gun and changing colors while the inside of the beans are not being roasted until much later.

                  I think youll be very happy going that route. Its an inexpensive path and one that gives you great control over the roast and with practice and experience allows you to produce beans as good as you can get from a professional roaster.

                    Lol it just had to make sure my arm was fully stretched out so there was my muscles needed next to no effort

                    And thanks for all the advice guys...
                    Ive looked into getting a second hand bread maker...
                    Seems pretty reasonable price wise...
                    Will try another batch soon and update on my progress

                      If you get a bread maker, you will think why didnt i do this sooner??? Mind you all respect to you if your one of these people who likes to come up with an idea which is a little bit different.

                      Either way roasting coffee is fun and addictive

                        haha, I guess I am in some ways one of those "people"...
                        But i only stick to my "something different" if it turns out to be something better..
                        I just like to play around with things I have already

                        p.s.: just waiting on people on gumtree to respond to me so I can get the breadmaker

                          Gumtree is where i started to look for a a bread maker, i then put a notice up at work and waited. Then all of a sudden i mentioned it too a good friend of mine who said... "I have one and i dont use it so please have it". I guess what im trying to say is also ask those who you think wouldnt have one, cause sometimes they do

                          The heat gun was the expensive part for me which is still going strong. I brought it from total tools we have here in Melbourne. IT only cost me $49.

                            could you use some bottom heat such as a gas burner to speed things up?

                              Interestingly, I tried another batch on the wok while still waiting on a bread maker... (because I ran out of coffee)

                              This time I brought the wok up to about 180 degrees on the stove before I put the beans in...
                              I got to a "TRUE" 2C in about 35 minutes...
                              which is way earlier than I would have without heating it up...
                              but it was harder to control and my roast was the slightest bit uneven...

                              Taste wise, still very happy with the results...
