Criollo means native or creole. In tobacco it is an older Cuban-seed type, grown for generations on the island and then in the New World. Some farms use criollo as filler; some as binder; some as a rustic wrapper. The word alone does not tell you which.
It sits in the same conversation as corojo and habano: Cuban ancestry, foreign fields. Hybrid names (criollo ’98 and others) exist in seed catalogs. This encyclopedia does not treat those catalog numbers as flavor facts.
If a page needs a country, it will say Nicaragua, Honduras, or Cuba. Criollo is the plant family, not the passport.
