Re: First Popper roast
I just did my first popper roasting, used 50/50 Peru and Brazil. I havent work out the temperature stuff yet but wanted to give it a try anyway.
First crack at about 2.5 - 3 minutes with second crack at 4.5 minutes. I pulled it then and let it cool.
I realise that at this time there is no way that the beans could develop/release the flavours they are supposed to but I thought it was a good start.
Temperature at present is about 30 degress.
Ive tried a tasting through the Presso and it tastes very smooth. I should have taken photos but Ive already bottled them to degas, Ill take photos when I try them again after about 4 days I think.

Re: First Popper roast
If I may offer an idea... I think cooling time is also important to record especially if youre stopping around 1C or 2C as they are exothermic at that time.
...but then what do I know about roasting - Im not even using a thermocouple! :>

Plus, anything else you think may be relevant or helpful down the track some day. Weighing the batch to be roasted is pretty important as TG says above, otherwise youre just adding to the existing list of variables that you have limited control over - Why do that?

Re: First Popper roast
For consistent roasts you need to measure so that you are starting with the same weight of beans each time.Originally posted by 40757A737B140 link=1284122262/38#38 date=1291875696I didnt measure my coffee either, just filled it to above the shark tooth line of the Breville Crazy Popper

Re: First Popper roast
You probably dont need to worry about the one way valve bags. I bought some, then read a comment someplace that said ziplock bags are ok because popper roasts are small quantities and the amount of gas released isnt an issue. Ive done 6 roasts now and no problems.
If you do use one way valve bags, put the roasted beans inside a plastic bag first (sandwich bags are good) then put that into the valved bag - it will prevent coffee oils from getting on the inside if the valves bag and you can then reuse them. The one way valve bags cost more than the beans you put in them.
As for waiting several days before trying them, why not roast two batches and try one immediately, then again over the next few days. I think youll be pleasantly surprised. The beans will improve over time, but tasting regularly as the flavours change is part of the fun.

Re: First Popper roast
Tango: I should have been more clear re: one way valve bags - I have a pile of 20 odd 250g bags from roasted coffee purchased from one of the local roasters.
Looking forward to when the green beans arrive, sounds like it could work.

Re: First Popper roast
Hey mallie,
Being a first time popper roaster too that sounds exactly like what I did!
Only thing is, the green beans dont come with one way valve bags, they come in either a glad snap lock or a cloth bag!
I found that with the roasts I did I didnt need to stir the beans, they started moving themselves although I did give them a stir every now and again just to make sure they were all moving. I didnt measure my coffee either, just filled it to above the shark tooth line of the Breville Crazy Popper - be careful with this, I was a bit too ambitious with the Brazil beans and I ended up loosing a fair bit on the floor!!
I tossed mine in a metal colander and agitated them - I didnt have a fan I could use!
I was apprehensive too but I tried a shot of the Ethiopian Limmu I roasted yesterday and it was pretty good (by my palate!)
Good luck!

Re: First Popper roast
Ive just ordered some green beans from bean bay after digging out the breville quick popper from the cupboard, to confirm it had the side vents, success.
From my research all I do is:
1) Head outside
2) Gently place in some green beans (approx 80g) turn it on, stir for a minute or so with a wooden spoon (until they move on their own?) get them to at least beyond first crack (typically 2-6 minutes) and then keep going until they look a good colour or second crack. (It may be worth using a fan to prolong the time until first crack?)
Then toss them into a colander to get them to cool down quickly, while agitating them?
Once cool toss them into a one way valved bag (that existing beans came in) wait a week and try them? Once happy with the results can look at things like a chimney mod to enable roasting more beans in a go, and perhaps some other tweaks to better control temp?
Im kind of apprehensive I will make some foul tasting coffee with this experiment, just wanted to double check the process and make sure Ive got the understanding correct.
If all fails - I hope there be some Canberran roasters to donate the left over beans too.

Re: First Popper roast
Gday Who...
Nothing wrong with doing it for the experience whatsoever and yes, the BM is a handy receptacle with a built-in agitating system - Nothing wrong with that either. Have a look through Koffee Kosmos threads about the KKTO, heaps of info about using the Turbo Oven with this design...
One thing about we CSers, when it comes to roasting coffee, the imagination is the only limiting factor when it comes to creating a home-roaster. All the best with which ever method you decide upon but dont forget to come back and show us what youve done....
Cheers,
Mal.

Re: First Popper roast
Im not concerned about the safety as I like to think I know what Im doing (but then doesnt everyone...).
Tinkering with the popper would be pretty straightforward, but Id not learn anything and the cost of a transformer and dimmer for the fan would be about the same as a heat gun.
I suspect a heat gun will be on my xmas list, although I did see a turbo oven for $49 today, which might be an interesting project.
Unless Im mistaken, the bread maker in a coretto setup is just there to provide a handy container and automatic agitation of the beans, so is not really necessary if an alternative is used.

Re: First Popper roast
I agree TG... 8-)Originally posted by 0539243F353423363E35510 link=1284122262/33#33 date=1290651526I think trying to electronical modify the popper is too fiddly and frought with danger (electricity kills).
Perhaps when years ago the popper was almost ubiquitous as the home-roaster of choice, fiddling was seen as a genuine option to increase batch size and control over the batch profile. With so many other great options available now for the home tinkerer, it just isnt worth it from many perspectives, especially safety....

Re: First Popper roast
Next step I took was bowl and heatgun.Originally posted by 545C525A5842425E525A310 link=1284122262/32#32 date=1290638898One thing Im curious about, given that a well known hardware store sells heatguns for $20 (two setting 300/600C), would a heatgun, wokand wooden spoon be a sensible upgrade when I outgrow my 99 cent popper? Or would adding fan and heat control to the popper be better?

Once you get more roasts under your belt youll probably see batch size as your next priority anyway.

Re: First Popper roast
My first beanbay order was delivered 7.15 this morning, first roast (90gm monsoon malabar) completed 7.45. Second roast will be tonight, probably brazil from starter pack.
Plastic cover for popper is now history, so time to Install the tin can chimney.
Is 3.30 about right for first crack in a cheapie mistral popper?
Im not sure if they got to second crack or not as there was pretty constant cracking from 3.45 until I pulled them at 620.
Looks like cs9/10. Will have a browse of youtube this evening if I have time and see if I can get a better idea of what to expect from roasting in a popper
The android coffee roasting app looks good, even notes ambient temp (didnt know my phone had a temp sensor).

All in all its been a good week. Got my popper, beans, PID/thermocouple and a copy of the professional barista handbook. All I need is for the SSR to arrive.

Re: First Popper roast
I have tried the peru again this morning 4 days post roast. Taste was great. Shot poured nice.
I am using a double basket. I roasted another 2x80gm batches this morning. 1st total time was 7mins. Wind picked up and my 2nd roast was 11.5 mins. Came out very nice.
