I lose between 15 - 19% bean weight when roasted.
Yours lost 17.33% - in the ballpark.
Looks like you could do 600g batches.
Do you have the round extension nozzle for the HG?
Hi all, in case anyones interested, heres the story of my first ever roast using a corretto roaster. Plenty of pics to keep you interested... ;) Im interested in feedback and comments/critique... please let me know what you think!
I managed to get my hands on a bread machine and a heat gun and together with stuff around the place, managed to rig this up: (Palsonic bread machine; Ozito heatgun; ikea table lamp, masking tape; portable laptop table with wheels; standing fan, exhaust fan; wash basin; metal sieve)
Prep for roast:
I got myself and starter pack and decided to roast the Brazil Ipanema Reserva Especial. Weighed out 300g and was ready to go.
30 secs in:
3 mins in:
4.5-5 mins in:
FIRST CRACK at 6min (too early?)
9 mins in:
SECOND CRACK at 10min
10:30 mins - stop roast and mad scramble to pour beans into sieve for cooling
My pride and joy! Piccies of my first roast
Before and after pics: Is it common to lose about 50g? (1/6th the original) - probably was a bit less than that as a few little babies fell out of the sieve...
From this comparison with the CS member card, Im guessing this is a CS9-10 roast?
Some arty photos:

Thanks for reading!

Thanks for stats re: weight loss!
Not sure what the round extension nozzle is - Im using a friends HG atm. Am about to head out to bunnings to buy my own - Im hooked! Thinking of getting the Ryobi or Bosch cheaper end ones. And going to head to Breville seconds shop to buy y own bread maker... so far, Ive been using borrowed equipment.
Welcome to Corretto World ben, I checked out pics on website, set-up looks good.
CS have another roasting tragic on their books now!!!
Welcome on board and looks like a great first roast.....
Id suggest a little less heat early on (raise heatgun or turn it down depending on the model) to reach FC a little latter (about 9-10 minutes) and then reduce it even further so SC is about 5 minutes after FC..
If you an organise for that fan to blow over the top of the BM..... directly at the HG.... that will prevent chaff from being sucked into the HG and also the hot air from being drawn back into the HG. This will extend the life of the HG as well as slow the roast down as it will remove some of the heat from the area....
But you are already very close to nailing it and your first roast should be really great in the cup. Congratulations!!!
Thanks JavaB! Ill post my cupping notes when I try it out on Teus/Wed, though I hope I can describe what Im tasting! Ive downloaded a taste/aroma wheel from somewhere else and Ill see if any of those adjectives match what Im tasting!Originally Posted by JavaB link=1210948224/0#6 date=1210986322
I did move the fan up higher to blow over the top of the BM and HG - thanks for advice though. THe fan swivels horizontally, so I also tilted it down when I was cooling the beans - exhaust from underneath and fan from above... is that a bit of overkill??? :P
OK, Im going to go do another roast soon and try my own blend! Hopefully the starter pack of beans blend well!

Sorry, not sure whats going on.
Very impressive, hope it tastes good too.
Nice photos by the way, thinking of doing this myself soon :)
Nice work Ben, a great series of pictures too!
As others have said, the weight loss is spot-on and the roast could be a little slower but I still expect it will be great.
So... how did it taste?
Its day 3 today - it is time! Will try it out this afternoon and post my thoughts here...
So, just wondering... what is the process after roasting?
After cooling (takes only about 5 minutes on my setup), what do I do with the beans? Leave it out in the open air? Put it into airtight and dark environment straight away? Whats the right way of treating a new born/roast bean?
After cooling my beans go straight into one way valved sealed bags..... and after sealing squeeze out any surplus air and then into my cupboard to rest.....
Depending on the bags you buy they will also be light tight (the ones Andy sells are black aluminium) some suppliers have bags with a clear side but I prefer the opaque ones..... And they can be reused lots of times if cleaned between roasts.

Ooops. I let mine sit out for a few hours (6?) - thought they needed to degas or something. What will that do to the bean? Ive since put it into said black aluminium valve bags which Ive kept from previously bought beans.
Some other home roasters do that as well...... some believe it reduces the amount of resting required...... but I have my doubts :-/
I dont think 6 hours will make a lot of difference..... in theory some oxidation of the coffee oils can take place in that time but I doubt the effect would be that significant.
The one way valves will let any of the carbon dioxide produced whilst degassing escape.... so I just put them straight in the bags - it is also interesting to see the bags swell as the gas escapes!
Great pics Ben, I enjoy a good process snap shot viewing. The six hour open air rest really shouldnt hurt them too much although oxygen is one of coffees worst enemys. My thoughts are for a first roast you have very well, I am impressed to say the least. Once you extend the roast times and shorten your air time of your next one, you should be on top of it.
Ok, here goes... I havent cheated and checked out what its meant to taste like and I am a complete novice at this. Only been drinking espresso in the past few weeks regularly, so my taste buds are still very inexperienced...Originally Posted by Andy Freeman link=1210948224/15#16 date=1211154658
Overall, it was nice! Pour was slightly fast - 60ml double shot in about 15 secs. 1 shot drank as espresso, 1 as a flat white.
No bitterness at all, slightly on the fresh side, maybe a little bit sour, great crema, medium to med-low mouth feel - not too watery (even with fast pour), not like syrup.
In terms of taste, Im really not sure. I can say what it wasnt better than what it was. It wasnt too chocolate-y or too much like fruit/flowers. Id go more with ashy and nutty maybe. Overall, it was quite mild.
The beans themselves smelt awesome! That was probably the highlight of the whole experience! The shot was nice, but the smell was great!
Good stuff Ben. *Now you will have to work on the espresso variables to improve the shot. *
A bit finer in the grinder, a little heavier on the tamp and you should pull the shot that will show the best from your 1st roast.
PS: The edits in the thread were me removing the discussion about the broken images (not needed now you have fixed it). *I also made the thread sticky for a while as its a great example of what can be done with some beans, a bread maker and a heat gun.
Great first effort!
Thanks to RayC and Andy for the compliments on the photos. Hope they are helpful for first time roasters...
Will try and pull a better shot and will post photos of the extraction just to complete the process!
Very nice first time effort with matching great pics!
To toss in a tidbit I picked up at the recent SCAA conference; For maximum freshness and longevity beans should be sealed in the valved bags while they are still cooling and have reached a temp of 27-32C/80-90F. :)
Java "Tidbits R Us" phile
Im sure Id be out of my league in understanding the answer to "how they came to that conclusion of 27-32degCs".... If it only takes a tid-bit Id love to know.Originally Posted by Javaphile link=1210948224/15#19 date=1211272447
Via experimentation I would assume. Ive spoken with several roasters since I heard that and they have confirmed from their own experiments that when the beans hit 80-90F/27-32C is the best temp to bag them. On a further note if you want to go for max shelf life like the big boys the bag should be flushed with nitrogen until the oxygen content is less than 6% and ideally 2% or less. Hows that for a tidbit?Originally Posted by YeeZa link=1210948224/15#20 date=1211337586
Java "Off looking for a bit of a tid" phile
Thanks for the tidy bit of info. Even better that I understood it. :)
Onya Javaphile, now yer telling us we need a thermocouple in the bean cooler... ::) ::) ::) ::)
;D ;D ;D ;D
Nice roast Ben, its good to see youve taken the time to setup a great looking corretto.
*Off to find some nitogen*
Maybe try a bottle of argon from your local welding supply. You could be onto a winner if it makes coffee last longer.
Congrats on your setup Ben. Nothing more satisfying than DIY.
Thanks all... am enjoying the fruits of my labour! There is a certain sense of satisfaction and achievement knowing that you have as much control as you possibly could have in the process of going from bean to cup to satisfied senses! Of course, it would be great yo have your own coffee plants and all that, but for vast majority of us, going from green to grind to gargle (?) and gulp is about as good as it gets!
Ive now done two roasts:
Brazilian Ipanema on further tasting... Im getting some kind of dark chocolate, heaps of rich dark crema, nice!
Had some Nicaraguan Highgrown and pulled it a little early at the first hint of second crack and it came up to CS6-7 on the scale. FC still early at 6mins, SC at 12. Need to make more adjustments... It tastes very very different to Brazilian and Ethiopian Harrar I am currently drinking. It is very nutty! Quite mild, very different, but quite pleasant really. Could perk up a blend maybe?
Some pics of my second roast:
Way to go Ben. Awesome results from your first roasts. Great pics too!
This is inspiring stuff. I am looking at doing some of this. Just got to get the equipment together. We are selling our house at the moment so I would have to be able to pack it away somewhere. This could create a problem with having the same set up every single time. Also, is it fairly easy to get a hold of the bags to store the coffee beans in? Thanks for all the info.
Hi there HamoAus - with the packing away thing - is it for house inspections?
I have mine on an old laptop table with wheels, so I just wheel it under a cover when Im not using it. I suppose if you had a shed or a large-ish storeroom, it could go in there also. The whole setup doesnt take much room at all - consists of BM, heatgun, and fan. For cooling Ive got an exhaust fan in a bucket, but for starters and for mobility, you can probaby just point the fan into a sieve holding the freshly roasted beans and itll still cool quite well. Repeatability of setup after dismantling is not a problem - the main factor is distance of heatgun from beans and even then this varies according to weather conditions and the type of beans - and for this, its a bit of trial and error, unless of course you get yourself a temperature probe and DMM to measure the temperature of the roast in real time (I dont do this as yet - just going with trial and error).
The bags have aluminium (? foil) lining and a one way valve to get air out but not let air in. You can get it from Coffee parts (site sponsor link on the left <---) or from beanbay (http://beanbay.coffeesnobs.com.au/?CategoryId=52 also on the left <---) when they are back in stock. They will post anywhere! So yes, it is easy to get your hands on those...
Let us know how it all goes!
I just "accidentally" bought my 1st green beans tonight on bean bay and I dont even own a roaster of any kind ;D so started to research it more (after having recently read Belindas experience in setting up the first "corretto") and then I found your post.
Hope I have as much success as you had on your 1st attempt - time will tell.
Thanks, yeh its for inspections but also when the time comes to move house too. I already have a couple of hobbies and I dont know if my wife will put up with another one. I like to ride motorbikes and grow my own vegetables and make all sorts of chutney. I want to roast coffee too, but there will be some negotiating time involved in this.Originally Posted by benandfaith link=1210948224/20#30 date=1213679153
Will post when I can negotiate all the barriers to entry. ( a little microeconomics reference there)
Or try the "Supply and Demand" play... whilst were into microeconomic ;D
Start with fresh ground beans from Beanbay or one of our site sponsors. Amaze your wife with fresh and great tasting coffee to create the demand, then before you know it ... a popper, or corretto, or IR, or Gene... I had a laugh
Ahh yes, the bribery method, part of the black economy. However, my wife hates coffee. She is very much a tea drinker. Back to the drawing board.
Great setup there benandfaith! Just a question though, I got a secondhand Palsonic breadmaker and I was wondering what setting you use when you roast? or was there some modding involved? :)
Thanks Evelyn!Originally Posted by eves link=1210948224/20#35 date=1216987182
I use mode 9 - dough I think. it shows up on the counter as 1:30 (1 hour 30 minutes). Press start. It takes 5 minutes of slow/intermittent turning before it speeds up to a continuous mode. So at 1:25/1:24, you can turn the HG on.
Hope that helps. If you need me to explain more, let me know!
Thanks for the advice Ben! I will definitely give that a try. Ive got my breadmaker, Im picking up the beans on Saturday and hopefully a heat gun sometime next week. Its all coming together! Im so excited!
No probs! Sorry it took me a while to reply... havent been on CS for a little while! Ive been too busy even to roast, and the weather in Sydney dhasnt helped! It looks good today though... but im still busy!
Hope your roast goes well! Make sure you post your experience and tell us how it went!
Great pics and looks a nice roast! Very inspiring ;)
Keep them coming!
Thanks Wisie!Originally Posted by wisie link=1210948224/20#39 date=1225173934
Unfortunately, Ive been up to my eyeballs in busy-ness and have resorted to buying beans from my trusted retailers for a short time. My second child is also about to be born (2 weeks... +/-) and then making the big move interstate a month or so after that. So when Ive set it all up in my new home, Ill be sure to post the new set up!
I can see only one small flaw in your roasting technique.
Your area is WAY too clean! ;D
I dare not post pics of my roasting setup, but it doesnt look like that! :-[
I do consistent 500g roasts and thinking about bumping to 625g making 4 roasts for a 2.5kg bag , I agree about bigger batches.
Good on ya, well done!
how can I get my hands on one of thoes colour charts for the bean colour?
Hey philby,Originally Posted by 546C6D68667D353D3C35040 link=1210948224/42#42 date=1245219951
They are in the beanbay section under other stuff.
Currently all I can see there is the replacement card option, though the original card option may only come up when the once a month beanbay is on.
Next beanbay get some greens, get a card and roast your head off!! ;D
Im guessing that the replacement card option is there because you have already received your CS roasting card and we only get 1 and have to pay for a replacement.
[slaps forehead] :-[Originally Posted by 6C646B6D653F3A0E0 link=1210948224/44#44 date=1245220693
Yup, thanks Ben
Next time Need beans ill grab one!! :)
Well Ive finally joined the corretto club and completed my first corretto roast.
A bit about the corretto: Its a modded Breville BB200 BM. Credit to the mod goes to Bret - a mate of Chris (cksyd). All circuitry was ripped out and the power connected to the wiring block sitting on top of the motor. Fortunately the startup capacitor alos sat on top of the motor so need to de-solder it from the PCB. The green switch fitted very neatly into the hole where the LCD display fitted.
The HG is a Ryobi two-speed attached to an old drill stand. Once again credit to Chris and Bret for most of the work but I was watching very intently *;D. The HG is attached by cable ties and the assembly swings away to make it easy to remove the bedpan...err..breadpan (sorry, that was a running gag on the day). I can raise or lower the HG by the spring-loaded handle to adjust the tempif needed. A future mod is to refit the depth gauge to the drill stand and work out how to maintain the handle at that distance.
I used a bead TC which fitted into a 5mm cable connector pressed into a hole drilled in the corner of the breadpan. The bead extends about 5mm into the bean mass. Entirely guesswork where to drill thewhole but it turned out to be the right place. Ill claim credit for this *;) The DMM is a non-data logging Digitech
The first roast was done at Brets place last Saturday to test her out. It was 250g of El Sal Boqueron Coop without the use of a DMM so it was Chriss experience that guided the roast and was pulled at start of SC. Turned out quite nicely.
The roast I did today was 450g of Peru Grace Villa. FC was at 10mins (185°C) and went failrly quickly to RFC. I completely missed start of SC and next thing I know it was into RSC by about 14 mins - I think. At this stage I was too busy trying to dump the roast to pay attention to the stats. Roasted weight was 360g.
The bean cooler is a bathroom exhaust stuck in a plant tub, sucking air rather than blowing. It was effective, cooling the roast in about 2 mins. It turns out the tub needs to be a bit bigger as the plastic guard melted. I used a wok stand to hold the colander off the fan but it was still too close.
Anyway, fairly pleased for a first effort though I imagine the roast will be a bit overdone. A big thanks to Bret and cksyd for making it happen and it has been great fun. Cant wait to do the next roast.
Dutch Coretto being build in Alkmaar, The netherlands (other side of the world)
Got fed up with a dual Popper setup (due to the small batch sizes) and am building a Coretto.
I allready did two runs with great result, and I am now improving my setup. *I want to bypass the circuitry and connect power directly to the motor. Just like Flynn Aus.
My BM motor has 3 wires: white, black and red. Does anybody know which wire is hot, neutral and ground????Originally Posted by 767C697E7E716563100 link=1210948224/47#47 date=1247023142
Without seeming to be rude, if you dont know which wires are which I wouldnt be advising you to rewire anything.
It can seem to be a very simple operation, but even knowing which wires should be which, I would still be checking them with a meter before I did anything.
