The scent of Bois d’Iris can be traced back to the rugged hills of Tuscany. The Iris Palida, the most aromatic of its kind, grows exclusively on this site of arid rocks and mild soil. Unlike the osmanthus flower whose epidermis cells secrete the essential oil, the iris hides its olfactory wonders within its roots. This concealment is so skilful that several years of complex processing are required to capture its secrets : planting, frequent hoeing by hand, to avoid damaging the rhizomes (roots), harvesting (three years later), selecting and husking, washing, followed buy one month of drying under sun on lattice trays , and five years of dehydrating in bags; the grinding and milling in factory. The powder that results from these six years of preparation is macerated in cold water.
