Rose absolute

Rose absolute is the solvent-extracted rose. In the absolutes that have been profiled, phenylethyl alcohol is the largest constituent, with citronellol and geraniol behind it.

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.

Each field carries its evidence: open a chip for the source, the quoted words and the confidence. A field with nothing behind it says so and stays empty.

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.
