I just roasted 8# this morning but no Brazilian. Bolivian, Costa Rica, El Salvador, PNG, Kau' but no Brazilian. I do have a few pounds in inventory. Once I roast again I'll throw in a batch of Brazil and see how she does. I've taken Joe's advice and started slowly with the heat and have only roasted at 4, 5, and 6. No over roast issues yet.
So far I am VERY HAPPY with the new roaster! Jim
