Subject: Very patchy looking roasts with Guat Palo Blanco using Gene Cafe, any thoughts?
 

Hi all just practising with my newly acquired Gene.
I'm getting some really patchy looking beans with the Guat palo blanco I'm using. Very chaffy bean so I'm wondering if that's the culprit? I got a much better roast with a guat injerto.
My latest roast was
preheated drum to 140
4 min @ 300
4 min @ 350
3 min @ 400
2 min @ 425
then 460 to 1st crack which was 16 min. Dropped then.
This might result in a baked roast, but I wanted to eliminate the possibility of too high temps at the front.  My previous roasts were 1st crack around 13 minutes
Any thoughts? Could it just be the chaff blackening the bean?
Oh, the amount was 227g
I started with 280g and kept dropping the quantiy.

thanks!
