Grown and produced under the same demanding standards the Oliva Serie O product line is just as good. But The “O” is made under a different strategy, namely the good old Cuban way of making “puro” (pure) cigars, that is, using a tobacco mix from the same country. The “O” sports a dark oily Piloto Cubano Nicaraguan grown wrapper and similar blend. This blend was achieved by growing Habano in the Esteli, Condega and Jalapa Valleys of Nicaragua.
