The mixture of different types of tobacco in a cigar, including up to five types of filler leaves, one or two binder leaves and an outer wrapper. Some specialty cigars are made with two wrappers, but this is rare. To achieve complexity in a blend, a cigarmaker will use tobaccos grown in various countries, or from varying regions of one country. He will also use tobacco from different primings. In many factories, the blends are well-kept secrets passed down from father to son. The blends at Tabacalera A. Fuente y Cia. in the Dominican Republic, for example, are not written down, and are only known by Carlos Fuente Sr. and his son Carlos Fuente Jr.
