Orris

Orris Root

Iris florentina, Iris pallida, Iris germanica

Common Names: Orris Root, Orris Butter, Beurre d’Iris, Orris Absolute


Description:
Orris is derived from the aged rhizomes (rootstock) of the iris plant—primarily Iris pallida and Iris florentina. The roots are aged for a minimum of three years to develop their fragrance, which is then extracted through several methods to yield various perfumery materials. Rich in α-irones, the aromatic compounds responsible for its violet-like, powdery aroma, orris is one of the most prized and expensive materials in natural perfumery.


Types of Orris Extracts

  • Orris Butter (Beurre d’Iris):
    Obtained by steam distillation of aged roots. Despite the term "butter," it is not a true concrete, but a semi-solid, creamy mass.
    Aroma: Warm, sweet, powdery, violet-like; long-lasting and elegant.
    Regions: France, Italy, Morocco

  • Orris Absolute:
    Extracted via solvent washing of orris butter, followed by careful vacuum distillation.
    Appearance: Pale yellow liquid.
    Aroma: Delicate, floral, faintly woody; used sparingly due to rarity and cost.

  • Orris Resinoid ("Resin"):
    Produced by solvent extraction (e.g., with ethanol) from aged root.
    Texture: Honey-like, viscous.
    Note: Often more affordable than butter or absolute. Technically a concrete but called a "resin" due to its texture.

  • Orris Powder:
    Ground aged root used in cosmetics, herbal sachets, and potpourri.
    Functions as a fixative and mild fragrance.
