What botanical species does osmanthus concrete come from, and where is it sourced?
Osmanthus concrete is the solvent extract of the flowers of Osmanthus fragrans (Thunb.) Lour. — Top uses the var. thunbergii Mak. (Jin-gui / Dan-gui, the fragrant gold/red-flowered group), sourced from Guilin, Guangxi, China, the classic osmanthus region.
Top declares the botanical name and cultivar group on every COA. Note this is a solvent-extracted concrete (flower wax + aroma concentrate) of fresh osmanthus blossoms, the intermediate toward osmanthus absolute — a natural, flower-origin material, not a distilled oil.
Top keeps the cultivar/variety declaration so the floral character (apricot / peach / woody ionone notes) is traceable.
