    The Story of Hazelnut leaf

    Hazelnut leaf offers a green, nutty whisper that brightens compositions, delivering crisp herbaceous tones with a subtle hint of roasted almond.

    Heritage

    The use of hazelnut parts dates back to ancient Egypt, where hazelnut oil appeared in aromatic waters for ritual cleansing. Medieval herbals recorded the leaf’s sharp scent, noting its ability to freshen indoor air. In the 19th century, French perfumers began experimenting with nut foliage, extracting a faint green essence that complemented the era’s emerging gourmand trend. The introduction of CO₂ extraction in the 1990s revived interest, allowing a clean, reproducible leaf note without the heavy residues of older solvent methods. Today, hazelnut leaf is prized for its ability to add a natural green lift to both classic and contemporary fragrances, bridging the gap between botanical authenticity and modern olfactory design.

    Did You Know

    "Hazelnut leaves contain natural aldehydes that give a fresh, slightly bitter green note, a characteristic rarely found in other nut tree foliage."

    Production

    How Hazelnut leaf Is Made

    Hazelnut leaf is harvested in early summer when the foliage is most aromatic. Workers hand‑pick the young leaves from orchards in Turkey, Italy and Spain, then spread them thinly to air‑dry for 48 hours, preserving volatile compounds. The dried material is milled into a fine powder before extraction. Today most perfumers obtain the note through supercritical CO₂ extraction, a solvent‑free technique that captures the leaf’s fresh aldehydes while leaving behind waxes and chlorophyll. The CO₂ stream operates at 35 MPa and 40 °C, conditions that prevent thermal degradation. The resulting amber‑gold liquid is filtered, tested for IFRA compliance, and stored in amber glass to protect it from light. Smaller batches may still use ethanol‑based solvent extraction, but this method can extract more bitter constituents, requiring careful distillation to isolate the desired green fraction.
