Rose absolute

No share is given here. The only figure in the sources is a single sample’s, and the site shows no percentage until a measured share with its medium and method is filed. The descriptors are the house’s own words.

A red rose

A 3D model of a garden red rose by Lassi Kaukonen (CC BY 4.0), not a botanical specimen of Rosa × damascena; simplified and scaled to about life size here.

To place it in your room, open this page on an iPhone or iPad (AR Quick Look) or an Android phone (Google Scene Viewer). The files below open in any 3D viewer.

A single red rose on its stem, a 3D model by Lassi Kaukonen ("Red rose", CC BY 4.0) - the same model the site’s rose renders use. It is a garden rose, not a specimen of the Damask rose (Rosa × damascena) grown for rose oil; it shows the flower whose petals are distilled for rose otto and extracted for rose absolute. Simplified for the web and scaled to about life size (45 cm): the size is a choice, not a measurement.

confidence B

Botanical

Rosa damascena Mill.

perfumery convention

the trade’s shared vocabulary; no single source

the absolutes in GC-1 (a commercial Turkish absolute, Isparta) and GC-2 do not name the species; the link to R. damascena is the trade’s convention for rose absolute

confidence B

Part

the trade’s shared vocabulary; no single source

the sources on the absolute do not state the part; the trade extracts the flowers

confidence B

Extraction

solvent extraction

perfumery convention

the trade’s shared vocabulary; no single source

an absolute is by definition the solvent route (concrete, then absolute); no source on record states the method for the cited samples

Harvest and processing

• picking of the rose blossom (harvest): by hand: only blossoms with at least one open petal are picked, with the sepals, without damaging the stem or the branches
  documented

  The harvest takes place over a 20 to 30-day period and requires special skills: between several hours before daybreak and the early morning only blossoms with at least one open petal are picked with the sepals, without damaging the stem or the branches.
