The Tatuaje Cojonu (pronounced Co-Ho-Nu) 2003, is what was a line extension of Pete Johnson's first line, La Selection de Cazador Reserva. Cojonu is short for cojonudo, which is Cuban slang for "ballsy". So, it's not a surprise that the Cojonu is supposed to be stronger & fuller than their other blends.
Don't let the 2003 date fool you either. That is the year that these cigars were blended. Not the year they were rolled. It is also worth noting that the original Cojonu 2003 had a Nicaraguan wrapper, but the blend now features an Ecuadorian Habano wrapper.
