Hi everyone!
I'd like to know if I'm the only one to get half of the weigh of my coffee after the roasting?
Exemple: To day I've received my behmor roaster and I roasted 113g (1/4 lb) of green coffee. After the roast, my coffee weights 60g .... approx one half of the original weight. I bought my coffee green beans from green beanries.
Is it normal? If it's normal, the green coffee worth more then roasted coffee! I don't understand .... Maybe I'm wrong with my calculs?

I regularly weigh my beans post roast. My average weight loss is 17%. I suggest you try 12oz at the 1#/P1 or P2/B setting. First carefully weigh out 12oz (339-340 g) of green. Roast to your preference...REMEMBER....the darker you roast, the more moisture loss there will be!
If you're roasting well into 2nd crack where beans are showing oil, you will find a more significant loss of moisture. But NEVER should it be 50%. Check your figures again.

If I want to get 1 lb. beans city roast I roast 1 1/4 pounds green. The darker I roast the more beans I add to get a pound roasted.

I roast 2.4 lbs greens to yield 2.0 + roasted on the RK drum, to full city roast, just short of a second crack. A 15-20 percent loss is quite standard, bean dependent.

I roast 240 grams, every 3 days, to a final bean mass temperature of 405df (FC). My shrinkage for most beans is 17-20%..Yesterday's batch of JBM peaberry was 200.5 grams, or almost 20%. Kind of costly..

Well ... I'm happy to read you all!
I thing I had made something wrong.
I bought the Choco Espresso brand from green beanries ... and In my Behmor 1600 I selected the P4 profile with the D program. I also push the " - " button once like it's said in the user manuel for a 1/4 lb. ...
At the end of the complete cycle my beans were not enought roasted. I mean, they were very light brown .. and some were still greenish ... None of them were black or dark....

I would suggest you do as I suggested...earlier. LOL
Weigh 12oz (339g). Roast at P1 or P2/1#/B
BTW, have you checked your preferred outlet for voltage?
Many here have a Kil-o-wat device (around $20-29 US) that delivers info on whats coming out of your wall. Plugging in the behmor into that will show you how the roaster is cycling, etc.
Ideally, at least 120v out of the outlet is best. If you're showing say, 116 at the start of the roast, you'll be baking your beans for sure.
