Neroli oil is a plant oil produced from the blossom of the bitter orange tree (Citrus aurantium subsp. amara or Bigaradia). Its scent is sweet, honeyed and somewhat metallic, whereas bergamot, being rich in linalool (which is the main component in lavender), has more of an aromatic, soft floralcy.
The blossoms are gathered, usually by hand, in late April to early May. The oil is produced by water distillation, as the blossom is too fragile to endure distillation with direct steam.
By the end of the 17th century, Anne Marie Orsini, duchess of Bracciano and princess of Nerola, Italy, introduced the essence of bitter orange tree as a fashionable fragrance by using it to perfume her gloves and her bath. Since then, the term "neroli" has been used to describe this essence. Neroli has a refreshing and distinctive, spicy aroma with sweet and flowery notes.
It is one of the most widely used floral oils in perfumery. It is a nontoxic, nonirritant, nonsensitizing, nonphototoxic substance. It blends well with any citrus oil, various floral absolutes, and most of the synthetic components available on the market. Neroli oil is a classic element in fragrance design and one of the most commonly used in the industry.
It also has a limited use in flavorings. Neroli oil is reportedly one of the ingredients in the closely guarded secret recipe for the Coca-Cola soft drink. It is a flavoring ingredient of open source cola recipes, although some variants consider it as optional, owing to the high cost.
