You are right for being curious. Among the best cigars in the world are the italian Toscano cigars, not yet sold in the US (but soon they will be), made with american Kentucky tobacco grown in Italy and according to a unique receipt of the Granduchy of Toscany two centuries old.
There is much to say about them, but I can just mention the fact that in Italy we can freely buy cuban cigars (no embargo for them), nonetheless italian smokers prefer Toscanos. There must be a reason, right?
