Besides the freeze,
I think the real concern is that the Coffee Producers in Brazil want more for their product due to much higher fuel and fertilizer costs.
They see other commodities going up and they wanna get PAID!
With bad weather , it'll slow the harvest. Now , there's talk about a trucker's strike in Brazil(Futuresource) ?
Hmm, fuel cost up, all other things will follow.
THe lower dollar doesn't help for sure. Look at Cocoa, the grains, all coming back to life lately.

Just my 2 cents worth.
