Adrien Neisson bought the factory and sent his brother Jean to Paris to study chemical engineering. When Adrien died in 1971, Jean took over the business until his death in 1986, leaving his knowledge and the business to his grandson Grégory, who at fifteen years old was too young to run the company. In order to keep the business in the family, Mrs. Neisson Vernant, a Paris-educated medical doctor, took over the company until he finished his studies, becoming the only woman to run a rhum (French spelling) distillery in Martinique. I bestowed her with the title of “La Reine de le Rhum” or “Queen of the Rhum.” The Neisson Distillery is the youngest of the Martinique distilleries. In 1900 there were 120 distilleries, today there are 9 distilleries and 14 brands. Neisson, run by Mrs. Neisson Vernant and Grégory, who is the Master Distiller, is the only distillery that never closed during World War I and II, and in a time when most of the distilleries are commercially run, they hold the impressive distinction of being one of only two family owned and operated distilleries.Neisson Rhum Agricole Blanc Neisson Blanc. Unlike other areas that make rum from molasses, Martinique uses freshly squeezed 100% sugar cane juice, before any sugar is extracted. Neisson bears the proud designation of AOC (Appellation d’Origine Côntrollée) on the bottle, and is called rhum agricole. What that means to consumers is that the sugar cane is carefully harvested, processed, fermented, distilled and bottled in Martinique according to strict government guidelines.
