  • First Corretto Roast! Looking for feedback

    Hello! I just built a Corretto roaster and roasted some Ethiopia Guji Alaka beans from Happy Mug. I am using a thermocouple to monitor temperature and hit first crack around 8-9 minutes in. Unfortunately, right in the middle of first crack my bread machine paddle stopped turning. I tried to fiddle with it but couldn't get it to start again, so I dumped the beans because I was worried they'd burn with no paddle movement.

    I was going for a light city roast, and although I probably pulled them a bit early, I think they look pretty good. I really enjoy SW roasting coffee, and my beans look very similar in color to theirs, so I'm hopeful that they'll taste good, but also am prepared for the worst!

    I think there is a French bread program on my bread machine that has a much longer dough cycle, so I am going to try that next time. Also, I believe it overheated, so I should also probably try to locate and remove the temperature sensor.

    It's a Toastmaster TBR15 if anyone happens to have any experience with that machine. Anyways, here are some pics. What suggestions or feedback do you folks have? Thanks!

    Welcome to Coffee Snobs Soules

    Try to modify the bread maker to run continuously (disable the element) will make life a lot simpler, 8/9 mins to first crack seems fast to me, you must have had the heat cranked up pretty high, I usually hit FC at around 14 mins @ about 200°C.

      Yea, I hit first crack a bit early perhaps, depending on who you ask. I've seen several people online recommend that FC at 8-10 minutes timing. For my next roast I'll probably shoot for a longer overall roast time.

      I'm going to brew the coffee up tomorrow morning and see how it tastes. I still have 1/2 lb of beans left to roast. For a natural processed Ethiopian, what profile would you recommend? Thanks!

        Time to 1st-Crack depends a lot on the batch weight.
        If roasting quite small batches, say ≤400g you would expect 1st Crack to occur from 10-12 minutes or less, so maybe the 8-9 mintes isn't out of the ballpark.

        Agree with Yelta though, would pay to modify your BM (or have a qualified person do it for you) such that you are in a position to stretch roasts out to 20+ minutes for larger batches.

          I roasted roughly half a lb of beans, which is about 230 grams, so perhaps the shorter overall roast time won't be such a bad thing? I just didn't want to ruin the entire bag if I messed up. Roasting half gives me a chance to try again later without ordering another bag. Anyway, I'm going to brew it up in a bit here this morning and try it. I'll report back later.

            Ok so I tried the coffee this morning and, to my pleasant surprise, it was some of the best I've ever had! There was no smokey burned flavor. It was really juicy and tasted like strawberries and blueberries! I would say it is on par with my favorites from SW and Counter Culture, which I wasn't expecting...especially from my first attempt! Very pleased with the results. Hopefully I can replicate this again, or even improve upon it.

              Way to go Soules75...

              Sounds like you're nailing the profile for those beans so I wouldn't recommend trying to change anything just now. The proof of the pudding, as they say, is being able to repeat the results you enjoyed previously, so if you can do that a couple or more times, then it would be reasonable to try something different and see how that reflects in the results in the cup.

              Good job though mate...

              Mal.

                Good point. Why change anything if I'm enjoying it so damn much?

                I removed the heating element from the bread machine. Unscrewed it and disconnected the two wires. Will this prevent the overheating error or is there a sensor somewhere I also need to disconnect?

                  Time to start experimenting Soules, by their very nature all Coretto systems are different, what works with one may not be ideal for another.

                  Put some time and effort into understanding the process, lots of info available on this forum, use the search feature.

                  Also good video's about Coretto roasting on YouTube.

                  Here's a good thread to start with.

                    Can you give us some photos of the internals?
                    Will help us to assist you with any mod's that might be possible...

                      As Mal mentioned, some photos will help. If you BM is anything like a Breville, there may be a little screwed in metal plate/tab in the side of the internal metal skin, which sometimes has two white wires attached? I believe this is the sensor which will trip out the unit if it gets too hot. On my first machine, I unscrewed this, taped it up and tucked it away near the front of the machine under the touch pad to keep it cooler, which helped even with standard dough cycles (in later versions of roaster this has been removed altogether).

                      The other thing which can help is to wrap your pan in fire blanket ($10 from bunnings) to insulate this from the working machine. This also has the added advantage of then requiring far less heat input from your gun to get a good profile … reducing the risk of scorching



                      Below is link to my gallery of mods over the years – might get some ideas

                        Aah! Bunnings fire blanket.... Just the thing, I have wrapped the outer skin in that heat proof foam with the shiny backing.

                        I will check out your thread Matt

                          I just roasted my second batch, and this time I used the French bread setting, which has an 18 min dough cycle, which is perfect. The bread machine did not overheat and everything went really smoothly.

                          I went a bit slower this time and managed to hit FC around 9-10 minutes. I let FC finish and let them roast for another minute or so before dumping them. They look great and after about an hour now, they smell incredible, just like the first batch. Hopefully they taste every bit as good too.

                          I think I am going to order more beans in bulk soon so I can experiment with different origins. I'll be on the lookout for some Kenyan beans (one of my favs) and maybe a Colombia, El Salvador, Costa Rica, etc.

                          Looking at Happy Mug, Sweet Maria's, and Bodhi Leaf. Can anyone speak to which of these is best overall?

                            There is a wide variety of green bean sellers available to you, some even with-in driving distance. What kind of quantity, quality, and pricing are you looking at?

                              I've had roasted beans from Happy Mug, SW Roasting, Ruby, Counter Culture, Red Bird, etc. if that gives you an idea. Of those, I liked Counter Culture, Ruby, and SW best, but they were all great except for maybe Red Bird, who roasts too dark for my liking.

                              I am very pleased with the green Ethiopia Guji beans I've been roasting and also happy with the price. I've just seen a lot of buzz online around Sweet Maria's and Bodhi Leaf and am curious how they compare (quality, variety, etc.) to Happy Mug. I believe Sweet Maria's is a little more expensive than Happy Mug, but if the quality is better, I'm not opposed to paying more.
