Oliva Serie O Maduro Cigars The Oliva Serie O features some of the best Nicaraguan tobaccos around. Following in a Cuban tradition, Oliva planted the same Habano seed tobaccos in three Nicaraguan regions, Estelí, Jalapa and Condega, to produce a truly rich and complex cigar. All Nicaraguan Habano filler and binder in a Mexican Broadleaf Maduro wrapper. The natural sweetness found in Mexican Broadleaf makes this blend full-bodied yet smooth. The Serie O Maduro features notes of dark tobacco with spice and rich cedar. It is an excellent smoke for the more developed smoker.
