Stove top roasting
I attach a pic of my third roast, done in a cast iron pot on an electric stove, solid plate. I heated the pot up first with the lid on and an oven thermometer inside. The thermometer was registering 300°F when I dumped 180 g Honduras beans in. I waited a bit for starting to stir, shaking the pot back and forth every now and then. First crack started at just less than 5 min. but it did not sound right to me: I expected an almost continuing cracking, but it was not like that at all. Sounded a bit unenthusiastic, if you catch my drift. The stove plate was at its highest setting. I kept on stirring and shaking until it sounded that 1st crack was almost done before removing the pot from the stove plate because of the rather large percentage (or so I think) of very dark and even some black beans, as you can see in the picture.
I then emptied the pot into a colander, took it outside where a bit of a nice cool sea breeze was blowing where I decanted the beans back and forth between the colander and a saucepan to cool the beans down.
Was the heat too high or what did I do wrong? Did I not stir vigorously enough?
To me it looks like an uneven roast. Some beans may have only just got to first crack, others may have reached second crack.
Most roast methods rely on the beans being in constant motion to allow an even application of the heat, so in your case, it looks like you need more constant stirring.
You are right in thinking 1st crack should have moved into a period of continual cracking (rolling first crack) and the fact that it did not, also suggests uneven roasting times.
The heat is certainly another variable, but it can get difficult trying to tweak multiple things at once. Perhaps just concentrate on the stirring for the next roast and see if it helps.
Try a heat gun as your heat source and a whisk as your stirrer. Stir constantly
Thanks Brett, I shall certainly follow your advice with my next stove top attempt. I shall also keep that in mind when trying the heat gun trentski proposes.
trentski, I believe you have a good idea there. Watched a youtube video yesterday demonstrating heat gun roasting and he did in fact stir without letting up.. I am also going to try a gas burner and a different roasting vessel and see how that turns out.

after having read so many good things about home roasting, I gave it a try this afternoon and came out ok (I suppose as a newbie and on my first attempt).
on youtube, there were loads of videos but most of them seem to have made it very dark whereas I prefer mine to be more medium with slight fruity/acidy flavours. So I went and bought "indian A" and "columbian popeyan" from a local roaster.
So what I did was to roast 70g of columbian and 100g of indian A in a pan separately (as that was the intention to have it all separate!) and managed to get to first crack and as it was approaching what I thought would be second... i decided to take it off the heat as I was smelling some burns. And at the end, I mixed the both batches into one and picked out some burnt beans (just a few).
And then after let it sitting it for a while (few hours) I gave it a try and made coffee with it and was not too bad! the coffee I got especially the indian a, has slight earthy taste so it was good. cant wait to roast them more and see how the second try turns out.
I did it on the gas BBQ and seemed to have got it very even....
Great stuff! I am going to try the gas burner and see if I can imitate your results.
I'm a hundred and something most into roasting like this
If I'm distracted while stirring (ie reading/posting above on CS) then I get the odd darker bean but if I'm diligent I can have 550-800g raw batches work out well up to 1000g. started on frying pan and spoon heat gun makes it much more even though
50-70k+g on a 9kg BBQ bottle $0.10-0.40c gas per kilo coffee
BBQ side burner
Ozito variable gun
Medium camp oven. I have a oval 1.3kg to try with 2 heat guns or go buy a whopping big one @ 2kg+ batches
Honduras Montana de comayagua +Columbian Volcan galeras + Guatemalan Finca something something organic rfa
I roasted stovetop for about 3 years, it's a good way to learn, and the stuff is drinkable.
Trouble is little to no consistency, and the flavour of the coffee doesn't come out very well as it's a slow and uneven process.
Bang for buck though it's right up there... well the bucks are very low anyway
