200 Gram Sample roasts

[Pear]

So I have been working on 200 gram roasts (last 5 or so) and had never done anything this small...250 was the smallest prior.

I think or thought I understand the world of less beans, fan and heat. I am used to working with a dense moist (11.8%) bean. Recently, I was also trying no fan till dry end. (only recently..so kinda a new)

After having a terrible result with a costa rican bean which I was careful with charge temp etc and no fan till dry end...First crack would not come till 208 degrees. SO I went back to my dense bean and everything I modified turned out the same. So I thought, ahh with out the fan it's not getting to the convection to the center of the beans...but then larger prior roasts did.

Anyways, its all seems to come back to the 200 gram size (which I want to use for samples) isnt working to well.

Does Anyone have feedback on that?

With the smaller amount of beans maybe the temperature probe isn't getting enough bean contact so your 1C temperature readout is wrong.

I agree with thusband, the temperatures you are reading are not the real temperatures of the beans. When roasting with such a low batch, you are going to have to rely on sight, smell, and sound.

I would use my same "general profile" but reduce the charge temp, gas, and air flow so as not to burn the beans.
