Spanish cedar wood, Spanish cedar, Cedro (Cedrela odorata) neither comes from Spain, nor is it cedar wood: it is a tree of the mahogany family Meliaceae. The Spaniards imported the fragrant, cedar-scented wood from South America and the Caribbean West Indies to Europe in the 16th century. The smell of the wood is particularly pleasant and aromatic, it absorbs moisture very well, and it is not attacked by insects: an optimal suitability for cigar storage is a result of these properties, which made the wood irreplaceable as cigar box wood. However, intensive overuse has made this wood a rare commodity - good qualities have hardly been available for years.
However, much of the alleged Spanish cedar offered on the market, especially in online shops, is often not at all spanish cedar but strong scenting juniper wood (Juniperus procera) from Africa, the USA (Juniperus virginiana) or something else usually strongly fragrant wood that is offered fraudulently. Also African mahogany species like Khaya, Sapeli, Sipo, Tiama, Okume, Doussie or Gabon are sold under false flag as Spanish cedar! Thiswood ruins expensive cigars by strong smells forever. It is as always in the economy: You get what you pay for.
