A cigar is a tightly rolled bundle of dried and fermented tobacco that is ignited so that its smoke may be drawn into the mouth. Cigar tobacco is grown in significant quantities in Brazil, Cameroon, Cuba, Dominican Republic, Honduras, Indonesia, Mexico, Nicaragua, Philippines, and the Eastern United States.Explorer Christopher Columbus is generally credited with the introduction of tobacco to Europe. Two of Columbus's crewmen during his 1492 journey, Rodrigo de Jerez and Luis de Torres, are said to have encountered tobacco for the first time on the island of San Salvador in the Bahamas, when natives presented them with dry leaves that spread a peculiar fragrance.  
   
     
  Quality cigars are still hand-made. An experienced cigar-roller can produce hundreds of very good, nearly identical, cigars per day. The rollers keep the tobacco moist—especially the wrapper—and use specially designed crescent-shaped knives, called chavetas, to form the filler and wrapper leaves quickly and accurately.  
Some cigars, especially premium brands, use different varieties of tobacco for the filler and the wrapper. "Long filler cigars" are a far higher quality of cigar, using long leaves throughout. These cigars also use a third variety of tobacco leaf, called a "binder", between the filler and the outer wrapper.  
  Once rolled, the cigars are stored in wooden forms as they dry, in which their uncapped ends are cut to a uniform size. From this stage, the cigar is a complete product that can be "laid down" and aged for decades if kept as close to 21°C (70°F), and 70% relative humidity, as the environment will allow.
