First let me say that there is no difference between Occidental Havana Sun Grown and Havana Sun Grown. We made the name change because Occidental Reserve was the first cigar manufactured by Hendrik Kelner for Alec Bradley, and it's a mild US Connecticut wrapped cigar. Havana Sun Grown, is a more full bodied cigar with a Connecticut Havana hybrid wrapper and is also made by Kelner. We didn't want the Occidental Reserve smoker to think that the Occidental Havana Sun Grown was similar in style and flavor to the Occidental Reserve so we decided to remove the Occidental name off the HSG. I hope this answers any questions you may have. Thanks for taking the time to write.
