The wrapper is the last tobacco leaf to be rolled on the cigar, so it is the one the smoker will see.
Habana 2000 or H2000, is a hybrid between El Corojo, Cuba's standard wrapper leaf last cultivated in the 90s, and a cigarette tobacco called Bell 61-10. Cuban cigar growers crossed these two tobaccos in order to get a wrapper leaf that would be more resistant to disease than the Corojo was. Although its introduction was controversial and the leaf was not widely accepted, its quality has improved over time and it is now being cultivated with success outside of Cuba as well.
