La Favorite has been producing Rhum Agricole on the island of Martinique since around 1843. The Blanc is made by distilling a fermented mash of freshly pressed sugar cane juice. A single copper column still is used to produce the blanc, which is taken off of the still at around 70% abv (140 proof). This white spirit is then rested in oak before being bottled at 50% abv (100 proof).
