So after reading forums and getting myself a bag of PNG Wahgi I had my first crack at roasting today. Boots in, not too much preparation, only way to learn is to do!
I measured out 250 grams and ended up with 220 but I think I've under done them somewhat attached is a pic of the green beans, my effort and a commercial roast which looks to my eye about a 9 on the 10 bean cs scale.
I didn't have a thermal probe but I used a laser thermometer which was really handy as I could pre heat the pan accurately, measure the temp of the HG, the BM pan and everything in between
Used some roasting profiles as a very rough guide and slowly got the beans up to about 205 at the 15 m mark and stopped at 20 mins. Thing was, the noise of the BM and the HG meant I couldn't hear any cracking. Tried switching off the BM for a second or 2 to see if I was hearing a RFC a couple of times - no joy
There's still some chaff on the beans and by the looks of another colour scale I've seen on the forums (with 16 colours) I might have not even made first crack. Nevertheless ill bag em and see how they go in 5days. Is there anything lost in reroasting them in a couple of days if they are too under done?
Cheers!

. I think the laser is giving me a very accurate temp in the pan even with moving beans so I will happily get them up another 30-40 degrees and see how I go.
