Petitgrain Oil (aromatherapy)

Petitgrain Bigarade Oil is a pale yellow or amber colored liquid of pleasant, fresh-floral, sweet odor, reminiscent of orange flowers with a slightly woody-herbaceous undertone and very faint, but sweet-floral dryout notes. The “bitter” topnote is possibly an association with the flavor of the oil which is slightly bitter. Bitter—in terms of odor—often refer to a sort of dryness, but it is accompanied by rich and sweet undertones in this oil. The terpenes in the oil are generally held responsible for the characteristic bitterness which in this connection also refers to a certain freshness. The freshness helps to subdue the overwhelming sweetness which would come up from the high content of linalyl acetate in the oil. In
