African bitter orange, known botanically as Citrus aurantium, is a type of citrus fruit native to Eastern Africa but widely cultivated in various parts of the world. It is closely related to the more common sweet orange but distinguishes itself through its more intense flavor profile and higher bitterness. The fruit itself is smaller and has a rougher, darker skin compared to its sweet counterpart.
The scent profile of African bitter orange is complex and multi-layered. It primarily exudes a sharp, tangy aroma underscored by a distinct bitterness that is more pronounced than in sweet orange varieties. This pungent scent is complemented by floral and slightly spicy notes, making it a popular component in the creation of perfumes and aromatic oils. The essential oil derived from its peel, often referred to as petitgrain or neroli oil, is particularly valued in the fragrance industry for its ability to provide a fresh, citrusy, yet slightly woody fragrance. It blends well with other citrus as well as herbal and floral notes, making it versatile for various aromatic combinations.
