Benedictine is a brandy or cognac based herbal liqueur beverage produced in France. Its recipe contains 27 plants and spices.
It is believed that Benedictine is the oldest liqueur continuously made, having first been developed by Dom Bernardo Vincelli in 1510, at the Benedictine Abbey of Fécamp in Normandy. Production of the liqueur was ceased by the monks in the nineteenth century, taken over by a private company founded in 1863 by Alexandre le Grand, which continues to produce the liqueur today.
The recipe is a closely guarded trade secret, ostensibly known to only three people at any given time. So many people have tried (and failed) to reproduce it that the company maintains on its grounds in Fécamp a "Hall of Counterfeits" (Salon de Contrefaçons) displaying bottles of the failed attempts.
The manufacturing process involves several distillations which are then blended.
