Lemon zest as a note emphasises the brightest, most sparkling aspect of lemon, the fragrant outer peel oils without any juice acidity. It smells intensely zesty, clean and effervescent, like grating fresh lemon peel, all aromatic oils and no sourness. In perfumery it is used to create the most vivid, sparkling citrus openings imaginable. It is even more fleeting than regular lemon oil, a brilliant flash of freshness. In Indian summers, lemon zest openings are electrifying, the purest possible citrus wake-up call. The best compositions pair it with a solid heart so the fragrance has somewhere to go after the zest fades. For maximum impact with minimum complexity, nothing beats real zest brightness.
