Bitter orange, also called Seville orange, is the sophisticated, complex citrus behind neroli, petitgrain and orange blossom, its peel oil smells bright yet bitter, green and slightly floral all at once. Unlike sweet orange's simple juiciness, bitter orange has depth, a marmalade-like bittersweetness with aromatic complexity. It anchors classic colognes and Mediterranean compositions with a grown-up citrus character. In Indian weather, bitter orange is more versatile than sweet citruses, its bitter edge keeps it interesting in humidity and its complexity suits evening wear as well as day. It bridges fresh and warm beautifully, making it ideal for transition weather. For citrus lovers who want more than simple sparkle, bitter orange delivers layers.
