The wrapper is the most important and expensive part of a cigar. Typically grown under a gauze tent (shade) to prevent the leaf from growing too thick, the wrapper must be smooth and have very few veins. The majority of a cigar's flavor is derived from the wrapper.

The wrapper is the outer tobacco leaf of a cigar, which wraps around the binder, which in turn, holds the filler. Wrappers are responsible for about half of a cigar's flavor, depending on the blend of filler tobacco and the wrapper, itself.

There are many kinds of wrappers, the most common of which are Natural and Maduro. 

Maduro Wrapper:

"Maduro" is the Spanish word for "ripe" and its use cigar-wise, is to refer to the extra time required and the dark colors achieved during the natural fermentation of maduro wrappers. Typically these wrappers are oily, plush with flavor, and earthy to the nose. Dark and as rich tasting as the earth from which they grow, Maduro-wrapped cigars are a favorite among many. They are the darkest of all the various shades of brown, and provide a wide array of tastes, from a sweet, mellow flavor to a robust and hearty taste that only the most seasoned smoker could appreciate.

Enjoy!
