The normal bean temperature for first crack by my roaster is 365 degrees.
And by no means is it calibrated when it come to temperature, but no matter, its just a mark on a gauge.
The Brazilian Rain Forest Alliance doesn't reach first crack until 420 ! 55 degrees more than the densest beans I roast.
First, I give it all the BTUs I can muster for the first ten minute. Then after first crack, I pull back the flame and ease it in towards second crack. I turn on the axillary fan to maintain 420 temperature, with smoke barreling out from all sides and hoping no one calls the fire department, I check the roast for darkness with the trier. Not wanting to take them beyond French Roast or have them scorch on me...I get set up for dumping the coffee. Any other bean would be near flaming, but not the Brazilian. I continually check the beans, oh, soon but not yet, just a little more heat now.
Bammm! Cut-em loose, and get them cooled down fast. Its that fast.
Never even making it to second crack. but just on the cusp.
These beans mixed with a lighter roast will sweeten up the pot.
At home, I like to add one third to one half of this Brazilian with a medium to dark roast.
Let me know how you like them.
