We Have Begun Producing Oak Wood CO₂ Extract

As a supercritical CO₂ extraction laboratory, Altraflora has added a new natural extract to its portfolio: oak wood (Quercus) CO₂ extract. Our production line is now live and we are accepting sample requests.

What is oak wood CO₂ extract?

Oak wood CO₂ extract is a solvent-residue-free natural extract obtained by processing toasted oak wood with supercritical carbon dioxide. The low-temperature CO₂ process preserves heat-sensitive aroma compounds intact, delivering a clean, high-purity profile.

Its signature scent is soft, balsamic and woody — a heart of vanilla cream and sweet teacake notes over a base of aged oak barrel, raisin and a light rum nuance. The key compounds behind this profile are vanillin, syringaldehyde, lignin-derived phenolics and oak lactone (whisky lactone / quercus lactone), the signature of whiskey and cognac aromas.

Where is it used?

  • Perfumery: Woody-balsamic base notes; aged-wood, leather and gourmand accords.
  • Spirits & beverage flavor: Reinforcing or mimicking barrel-aging character in whiskey, cognac, brandy and rum; enriching color and tannin structure.
  • Accelerated maturation: Achieving the woody-vanilla character of traditional barrel aging in a shorter time.
  • Food flavor: Warm, vanilla-woody nuances in baked goods, desserts and confectionery.

The Altraflora approach

Pure CO₂ is the only solvent in our process — no petrochemical residues. Our supercritical CO₂ production line lets us deliver the extract with a consistent, standardized profile. We also offer manufacturers analysis, characterization and formulation consultancy.
