Mature and Oscuro wrappers are two types of tobacco leaves used to roll cigars. Maduro wrappers are usually made from sun-grown dark tobacco, while Oscuro wrappers are the darkest type of wrapper available, typically produced from fire-cured or double fermented leaf.
Maduro wrappers have a sweeter flavor than other cigar wrappers due to their higher sugar content. They tend to be thicker and more oily than lighter colored varieties. The color can range from very dark brown to almost black.
Oscuro wraps are significantly darker in color than maduros, ranging from a deep chocolate brown to nearly black in color. The flavor is richer and smokier than that of the maduro wrapper due to its intense curing process which results in an increased amount of oils and sugars present in the leaf. They tend to be stronger in body as well as flavor when compared with maduros.
