Its compositions are based on lemon, orange, bergamot, grapefruit or mandarin, with other citrusy, aromatic and tart notes for men and floral notes for women. The peel of an orange, also called the zest, is used in many cooking and baking recipes to add a tangy orange aftertaste. The zesty aroma created from shaving the orange peel best describes this nuance.
