David Chang Posted March 27, 2022 Report Share Posted March 27, 2022 first time roasting coffee ever. i've been waiting a long time for the motor and it finally came. equipment: rotisserie drum (amazon), tritogenia variable speed motor, thermometer gun. beans: ethiopia sidamo goal: medium roast to 210-215c (bean temp). what happened: motor speed was 55 rpm (max). dome temp 350-380f. after 20 min, still looked greenish. upped temp to 400-420 dome. finished roast in about 38 min. longer than i had anticipated. 250g in. 210g out. 40 grams of chaff and moisture loss? color looks pretty uniform. i was happy with the result, but i have no idea how it's going to taste. i did not hear any cracking. maybe it was the thick walls of the kk, but i put my ear against the exhaust and heard nothing.. i was told i need to degass for a few days, even over a week if i want to run it through my espresso machine. does anyone know how to upload video? i can't seem to do it on this forum.. 1 Quote Link to comment Share on other sites More sharing options...
C6Bill Posted March 27, 2022 Report Share Posted March 27, 2022 (edited) I'm not sure if there is a way to upload video, maybe host elsewhere and embed ? I'll give it a try, tried and failed Edited March 27, 2022 by C6Bill Quote Link to comment Share on other sites More sharing options...
Cheesehead_Griller Posted March 27, 2022 Report Share Posted March 27, 2022 (edited) Weight loss is crazy in coffee beans from what I've experienced. I roared coffee beans in a roaster a friend borrowed me for about six months. I was roasting roughly two to three pounds per month. I was ordering green coffee beans as well. I did the math and when I buy roasted beans from the coffee shop I get a full pound of roasted beans. The input weight prior to roasting was probably somewhere between 1 and two pounds. In the end, my friend took his roaster back and I never invested in one. Note, the roaster I was looking at is about $500. I cannot offer input on your beans. I always use the crack to determine the roast. I spoke to Dennis about roasting beens in the KK and he didn't think it was a good idea. He recommended a peanut roaster off of Amazon. I have yet to try it but I may soon. My plan was to roast some beans after I finished a cook on the KK. It would be heat soaked and ready to go. I wonder if I can get a basket like that for my 32.

MacKenzie Posted March 27, 2022 Report Share Posted March 27, 2022 I've been roasting coffee beans for ages with the Hottop Roaster. I have been happy with the results but I am no expert. 1 Quote Link to comment Share on other sites More sharing options...

The espresso endeavor has been quite expense and over budget. Similar to the KK. Edited March 27, 2022 by Cheesehead_Griller Quote Link to comment Share on other sites More sharing options...
MacKenzie Posted March 27, 2022 Report Share Posted March 27, 2022 These are indeed long term investments but I've found there are really no shortcuts. Quote Link to comment Share on other sites More sharing options...
David Chang Posted March 28, 2022 Author Report Share Posted March 28, 2022 @Cheesehead_Grillerthe drum i got was made for those little table top ovens with rotisserie attachments. i had to pull off tabs on the sides to make the holes bigger to fit my spit. but the latching mechanism is rather weak and i felt like if you put too much beans inside or roast bigger things like chestnuts, the door might just bust open. RK drums make better ones, but they are much more expensive. i was advised by a local coffee roaster that the weight loss i experienced was typical for medium roast, but similar to dry ageing meat, you won't get the same yield. i haven't done the math, but i think the cost for me to roast myself is a little over 1/4 the retail of shop roasted beans. but i also need to factor time. and i would only do this if i was cooking something else. i don't see burning charcoal just to roast coffee alone. 1 Quote Link to comment Share on other sites More sharing options...
David Chang Posted April 1, 2022 Author Report Share Posted April 1, 2022 couldnt wait, so i brewed a pour over and pulled a shot today. definitely a shade darker than i like for pour over. need to remember it grows darker the next day. lots of espresso crema from the pull. but for a milk espresso drink. very smooth and easy drinking. thing is impossible to replicate until i settle on the proper kk temp for roasting so its not another 40 min roast… delicious nonetheless. pardon for the garbage latte art👌 2 Quote Link to comment Share on other sites More sharing options...
Poochie Posted April 1, 2022 Report Share Posted April 1, 2022 Cool snowman! I never could make those cute critters with my espresso milk. Mine looked like road kill. 1 2 Quote Link to comment Share on other sites More sharing options...

David Chang Posted April 5, 2022 Author Report Share Posted April 5, 2022 (edited) roasting coffee is fun, and i guess worth while if you are roasting like a kilo. this time with help from fireboard pro. the thing with this setup is you can't really hear the cracks due the thick concrete walls of the kk and the noisy motor. Brazil Natural 250g in 207g out. Columbia Washed 250g in 208g out. Ethopia Sidamo 250g in 208g out.
