Can anyone tell me if this is actually a cuban grown coffee or is it the roast/flavor they add that makes it cuban? It says 100% Arabica but nothing about where it comes from. can't find anything online either.

Smuckers bought Rowland Coffee Roasters, which owned the Bustelo brand. It's not coffee that is sourced from Cuba, just branded as Cuban style coffee. I believe it's still roasted in Miami.
