I am new to the world of roasting. I have roasted 5 batches, but I dont think I have things correct. I would like your help.
My setup is a popper, with vents on the side. I have inserted a thermocouple in the side today to monitor temps. I have added a tincan to use as a chimney.
I add 90grams of green beans after waiting 30seconds for the popper to warm up, they spin by themselves.
I have been stopping my roast after 6 mins from reading people comments, but I cannot tell if I am reaching second crack? today I let the roast go on for 13 mins and recorded the temps and description each 30seconds. Can you tell me when I should have stopped roasting? I am using PNG beans.
here is my log;
-0-30 25c turn on popper and wait 30 seconds.
0:00 156c. dump 80 grams of green PNG beans.
0:30 177c. some cooking smells coming from beans
1:00 186c
1:30 196c some browning to beans.
2:00 200c - sounds like first crack startin (a single crack sound)
2:30 204c - no cracking sounds
3:00 210c - some crackling sounds plus small amount of smoke
3:30 213c - more crackling (sounds like the peak of popping sounds, quite active)
4:00 215c - some more loud crackling
4:30 218c - cracking seems to have stopped
5:00 218c - slight crackling
5:30 220c - a few pop sounds
6:00 221c - pretty much silent
6:30 222c - no sounds
7:00 223c - more silence
7:30 223c - more silence
8:00 224c - cracking sounds, but could be the sound of beans tumbling around?
8:30 222c - sounds pretty quiet in there. bans are a dark brown, but colour looks nice
9:00 225c - some rattle sounds, could be cracking, but could just be the beans hitting the walls
9:30 225c - no change
10:00 227c - divots start being spat out the chimney. in 30 seconds 4 divots have been spat out.
10:30 226c
11:00 226c - some more divots spit out, say another 4 or 5.
11:30 228c
12:00 227c sounds like 4 or 5 crackle sounds, 4 or 5 divots pop out
12:30 227c more cracking and divots - say a total of 15 divots have come out in the last 2 mins.
STOP and dump beans onto cooler. beans cool within 2 mins.
I have included three photos. they are of my beans roasted at 6 mins, 9 mins and the ones from this sample at 13mins.
the 6 min beans brewed from my espresso taste green, a bit like grass or tree leaves
the 9 min beans taste pretty good
the 13min beans, I have not tasted, but expect them to taste good, even though they have what I would call divots, or craters.
so, what is your interpretation of what is going on?
Thanks/

Can you keep image size to a maximum of 640(W)x480(H) pixels please mate? Larger images can slow down page loading considerably, especially for people with limited bandwidth connections.....
