Raspberry leaf

Harvesters collect Rubus idaeus leaves at the peak of early summer in France's Loire Valley and Rhône‑Alpes. After careful hand‑picking, the leaves are air‑dried in shaded barns to preserve volatile oils. The dried material enters a low‑temperature solvent extraction, typically using hexane, for 8 hours. The solvent dissolves aromatic compounds, then is removed under vacuum, leaving a thick, amber‑colored absolute. Yield averages 0.4 % of the dry leaf weight, and the final product retains phenylacetaldehyde, hexenyl acetate, and subtle raspberry fruit notes. The absolute is filtered, decanted, and stored in dark glass to prevent oxidation before shipment to perfumers worldwide.
