Selected Tobacco products are known for their meticulous aging process once the cigars have been rolled. The cigars are placed into cedar-lined rooms while raising and lowering humidity to allow the cigars to cleanse themselves over time. For Alfonso Gran Selección this process takes five years & their final aging is done in rooms lined with French Oak. The use of French Oak in the aging process was also used for the Alfonso Añejo and Byron 1850 lines.
