Q. What Is the Drying of Plants Used as Perfume Ingredients Called?

A. The first plant material that comes to mind when I think of drying is the rhizome of iris (in Japanese). Because it is dried for three to four years to increase its aromatic constituents, this is sometimes called “maturation,” or aging. Generally, though, I think the only term is the ordinary one, “drying.” My guess is that, in most cases, extraction begins straight away, so drying is not often an important part of the process.
