The phrase alludes to items, often related to perfumery or aromatherapy, that contain approximately 28 grams of aromatic substances. This quantity serves as a benchmark for comparing the concentration and intensity of various fragrances. For example, a small bottle of perfume extract, an essential oil blend, or even a collection of solid fragrance samples might collectively possess this approximate weight in scent.
Such a concentration allows for experimentation with layering different scents, creating custom fragrances, or experiencing a range of olfactory profiles. Historically, smaller, measured quantities facilitated trade and travel, allowing individuals to carry desirable fragrances without bulk. This concentration level balances portability with a sufficient volume for repeated use and a discernible aromatic presence.
