  1. I’m interested in the Behmor Jake 1kg roaster they are developing. Interested in the price point it will come out at given the focus of the media that has come out around it!
  2. @SamB I would be interested to know how much the V2 set you back, including import duty/VAT if you are willing to share? thanks Guy
  3. So it’s the weekend and time go get a little roasting in. On the right Ethiopia Limu Gr2 charge in 250g Target temp 1: 238c Target temp 2: 233c Dry End: 5:15, FC: 12:30 End: 13:15 min:sec - Temp C 0:30 - 83, 1:00 - 96, 1:30 - 111, 2:00 - 129, 2:30 - 143, 3:00 - 153, 3:30 - 163, 4:00 - 171, 4:30 - 184, 5:00 - 189, 5:30 - 194, 6:00 - 199, 6:30 - 204, 7:00 - 207, 7:30 - 211, 8:00 - 214, 8:30 - 219, 9:00 - 222, 9:30 - 224, 10:00 - 227, 10:30 - 230, 11:00 - 232, 11:30 - 234, 12:00 - 237, 12:30 - 238, 13:00 - 233, 13:15 - 233 Weight out 216g On the left, Tanzania AA Mbeya Ndugu charge in 250g Pre heat around 80c from prior roast Target temp 1: 238c Target temp 2: 233c Dry End: 6:30, FC: unsure, End: 16:30 min:sec - Temp C 0:30 - 98, 1:00 - 125, 1:30 - 143, 2:00 - 157, 2:30 - 163, 3:00 - 177, 3:30 - 185, 4:00 - 191, 4:30 - 198, 5:00 - 203, 5:30 - 207, 6:00 - 213, 6:30 - 216, 7:00 - 220, 7:30 - 223, 8:00 - 227, 8:30 - 230, 9:00 - 234, 9:30 - 237, 10:00 - 238, from 10:00 until 15:00 - 238, 15:30 - 233, 16:00 - 233, 16:30 - 233 End Weight out 211g i do find it very difficult and/or I can’t pin first crack some times. how do there roast sound guys? Should I have the temp set to 240 and then keep the temp when I hear first crack? I did another roast after this of Malawi AA Pamwamba beans and I again only had temp set at 238 and didn’t identify first crack! I defiantly heard some solo cracks but noted 12:00 mins and 14:00. I defiantly heard it on the Ethiopia beans very clearly, is my temp now too low and therefore not high enough for the other beans, as I know it will vary. Do there roast times seem right for a light/medium roast? I took the Malawi beans to 16:00 Thanks Guy thanks Guy.
  4. Thank you for all the guidance and advice all, after taking a small delivery from Small Batch Roasting I’ll be back to it this weekend! fingers crossed for some better results
  5. Hi All, I cant express enough gratitude to you guys helping! @DavecUK, absolutely right and i will try and provide a little more (this is not an odd game of pictionary)! So second attempt at the same beans (Columbia Tolima). Lower weigh in to avoid the high chaff clogging the GC. General thoughts The roast was un-even. some good looking (larger beans) with a small bit of silver skin vs some (typically smaller beans) that look fairly dark. See the pics attached. There was still a lot of silver skin covering the whole bean at a guess 5% of all the beans. Roast Details (as available on the Gene Cafe) Weight in: 215g (that all i had left) volume was around 275ml (in the jug) Pre Heat to 150c Target temp 1: 238 from start to FC start plus 1min 30 Target temp 2: 233 until end. Weigh out: 187g volume was around 400 ml Dry end was 5:45 min/sec FC was 11:04 [Temp down to 233 @ 12:30] Roast End was 13:35 When i finish the roast i put it into a colander that is sunken in to a card board box that is attached to the hoover to draw air through the beans until cool. this is usually done in about 2 mins or just over. Notes through the roast 4:00- Beans to Pale Green 5:35 - Beans to yellow 6:00 - Yellow Brown 8:00 light brown 10: brown (still with quite a lot of chaff) 11:04 FC start [c.12:30 temp to 233] 13:35 - End & cooling Is this difference between beans some what out of my control given the difference between bean size?
  6. Hi guys, I need help with a prior roast. It's not as easy to see from the photos but there are spots of oil all over this roast. Is this because I took it too high in temp? It was one of the earlier (first) roasts I did on my Gene Cafe. The oil was certainly not present after I closed the container after 2 days degassing. The roast was darker than I was aiming for and on my (miss guided wisdom) I had the Gene Cafe temp set to 245c, kept it there for 45 secs and then ended the roast. Development was very short given I ended the roast about 1 So is this an effect of taking it too high in temp? Thanks Guy.
  7. @Rob1 thank you for the help, really appreciated as I’m still very new to roasting. DE (for me) is Dry end. When I can see no more green in the beans. My thoughts are I will try a roast of 220g of the Columbia and set the temp at 238, wait 1min into FC from FC start (I.e. rolling) then drop to 235. I took the profiles from Roast Rebels; https://roastrebels.com/en/roasting-knowledge/coffee-roasting/gene-cafe but I’m learning this may not be best to follow after also reading the Dave C guide that also comes from BB.
  8. The results on the beans from El Salvador are pretty good. The beans from Columbia just clog up the air exit and smoke the place out. Columbia beam is a problem I have been doing 250g of green beans in Tried 2 profiles. First: Target temp 1: 245 -> FC Target Temp 2: 240 for 45 sec -> end DE: 5min 8 sec FC: 12 min 15 sec Dump: 13 min 0 Profile two Target temp 1: 150 for 6 Min Target Temp 2: 245 until FC Target Temp 3: 240 for 45 sec -> end First crack is very difficult to hear I'm finding and the final cup is smokey but the chamber does fill considerably as the air exit is clogged with chaff. Any recommendations?
  9. Hi This thread was superb and some great advice. It’s been a busy one at work so a little difficuot to update the forum. i took the plunge and got Gene Cafe from BB a week ago and I’m currently on toast number 5. And Wow, what a learning curve! I feel I have made leaps and bounds just in that short about of time by writing as many notes as I can and cupping the results (after de-gassing) to understand each variation of roast on the final cup. @iroko how did you feel the Cormorant compared to the Gene Cafe with regards to learning the machine. Did you feel the Gene Cafe set you up well and therefore maybe you were producing good roasts after a few attempts or feel like it was a little more back to square one with all the additional control/variables? Also are you using BT and ET into any software? Thanks Guy. Images to follow
  10. TAKE 2! 😊 Hi All, I'm after thoughts and recommendations for a home coffee roaster and thought there don't seem to be a topic listing all the current 2019 options in the UK! As far as i can see there are the options: Gene Cafe from BB @ £500 - a small electric roaster, great to learn on but maybe a little limited on control. Un-modified it will do on OK job of roasting 250g from what i can tell in the threads. Hottop roaster from the London warehouse (i emailed the supplier through the e-portal last week) @£,1450 + £80pp this will allow you to have greater control with both fan and heat (electrically powered), also giving the ability to connect to software such as Artisan. It will roast you up to 250g plus give you the tools to mirror a roast saved profile for consistency. Cormorant CR600 c.£1600 this is Gas roaster and looks the business (looks are subjective) and will roast up to 600g per batch. I do have a concern that its not CE rated. Again this roaster will give control over heat, fan and drum speed. this also has the ability (with additional thermocouples, allowing software connection). Then we are on to the Amazon Dalian and Aillio Bullet, i'm less aware of these but both are in the region of £2,500 but come with all the bells and whistles you would expect at this price point. Both of these are capable of roasting 1kg in a single batch but at this point i now start to think..... how much do i need to roast at a time? I'm not commercial and neither have a wish to. But is this the price you have to pay for a decent roaster? What is going to have the capability closely match that of a specialty roaster with regards to capability? (excluding the roasters skill in this instance). Thoughts and other recommendations would be welcome. A small line about me: I love GREAT coffee, I tend to get thought about 1.5kg - 2kg a month and i use my Rocket espresso machine and filter. I have a passion for coffee and look forward to turning my hands to home roasting. I understand that whilst you may save cost long run, i am more interested in the challenge and learning the skill. that said im not sure dropping £2k+ is the best idea unless this is really going to give you the key to great roasting for many years (the machine will payback over its life time). I'm starting off and have never home roasted however i want to get a roaster that is going to be able to product a close to commercial (a specialty roaster) coffee and last a good few years allowing me to learn and improve my roasting skills. Thanks Guy
