Anywhere from a few months to several years, depending on whether it’s a straightforward commercial release built from an existing accord or a genuinely new composition being developed from scratch.

Where the time actually goes

A perfumer might go through dozens or hundreds of trial formulas, called “mods”, tweaking ratios by fractions of a percent each time before a brief is signed off. Then there’s stability testing, checking the fragrance doesn’t discolour or separate over time and in different conditions, consumer testing panels for larger commercial brands, regulatory compliance checks, and sourcing raw materials in the quantities needed for production. Smaller independent or artisan perfumers can sometimes move faster simply because there are fewer approval stages, but the actual creative development of the scent itself, the back-and-forth of adjusting a formula until it’s right, rarely happens quickly no matter the size of the house.

Why rushed perfumes tend to smell rushed

Maceration time alone, letting a finished blend rest so the ingredients marry properly, can take weeks to months. Skip that and a perfume can smell slightly disjointed even if the formula itself is good.
