Does “Bourbon” mean that it is extracted with bourbon alcohol?
No, Bourbon refers to the region (Madagascar, Reunion Island, etc.) in which the vanilla is grown and has no relationship with the alcohol by the same name. Many people use the word Bourbon to refer to the Planifolia species of plant that is most prevalent in Madagascar, Mexico, Papua New Guinea and elsewhere. The name Bourbon refers to the French Bourbons who ruled Madagascar at the time of the first vanilla cultivation there.
