Criollo is primarily used in the making of cigars. By most accounts, it was one of the original Cuban tobaccos that emerged around the time of Christopher Columbus. Criollo means “native seed”, which means that e.g. “Dominican Criollo” may or may not have anything to do with the original Cuban seed.
At one point, it was then discovered that when Criollo is grown under cover, as opposed to growing it in the sun as was traditionally done, it can make a very suitable wrapper leaf, given the proper care and conditions. Criollo can also be used as filler. Some of the first Criollo seed grown for wrapper was grown in Nicaragua, but is also grown in other places, e.g. Honduras, Mexico and Bolivia.
