Eau de Citron Noir Eau de Cologne is a unisex fragrance created in 2018 by Hermès perfumer Christine Nagel. It offers a sophisticated citrus-woody composition built around the paradox of black lemon—bright yet smoky. The scent opens with sharp lemon and lime, transitions into a heart of black tea and citron, and settles into a base of guaiac wood and cabreuva wood. The result is a fresh yet mysterious fragrance, combining vibrant citrus with dark, smoky undertones. Presented in Hermès’ iconic lantern-shaped bottle in deep blue, it belongs to the Hermès Colognes Collection, known for its playful yet masterful exploration of raw materials.
