Eau de Cologne
Eau de cologne (EDC) means two things: a light fragrance concentration of about 2-5%, and the original citrus-herbal style created in Cologne in 1709.

Eau de cologne — EDC on the box — carries two meanings that share a name, and most confusion about the term comes from not separating them. The first is a concentration grade: roughly 2-5% aromatic compounds dissolved in alcohol, which sits below eau de toilette and above eau fraiche on the strength ladder. At that strength it is top-note-driven, light, and short — usually a few hours at most before it fades close to the skin. The full ladder, from parfum down to eau fraiche, is broken out below.
The second meaning is older and more specific: the original cologne style. In 1709 the Italian-born perfumer Johann Maria Farina, working in Cologne, Germany, built a fresh blend of bergamot and other citrus oils with herbs over alcohol and named it after his adopted city — "a scent that reminds me of a spring morning in Italy," as he put it. The structure became a template: bright citrus on top (lemon, bergamot, orange, neroli) lifted by aromatic herbs like rosemary, lavender, and petitgrain. The most famous descendant, 4711 Echt Kölnisch Wasser, has run on roughly the same seven materials since 1792. So a fragrance can be "a cologne" in style — citrus-herbal and bracing — without being an eau de cologne in concentration, and vice versa.
One more wrinkle, mostly American: in everyday US usage "cologne" is shorthand for any men's fragrance, regardless of its actual strength. That is a marketing convention, not a technical reading — plenty of fragrances sold as "cologne" are eau de toilette or eau de parfum concentration. When you want to know how a bottle will actually behave, read the grade on the label (eau de toilette, eau de parfum) rather than the word "cologne" on the front.

- Eau de cologne (EDC) — the concentration
- A light grade at roughly 2-5% aromatic compounds, below eau de toilette and above eau fraiche. Top-note-driven and short-lived — a few hours at most. The lightest alcohol-based grade in common designer use.
- Eau de cologne — the style
- The original fresh, citrus-herbal fragrance created in Cologne, Germany, in 1709 by Johann Maria Farina: bright citrus (bergamot, lemon, neroli) over aromatic herbs (rosemary, lavender, petitgrain). Traditionally unisex. 4711 (1792) is its best-known survivor. A fragrance can be a cologne in style without being EDC strength.
- Concentration
- The percentage of aromatic compounds (the fragrant oils) dissolved in the alcohol-and-water base. Higher concentration generally means more intensity and longer wear — and is the single thing the 'eau de' label is telling you.
- Eau de toilette (EDT)
- Around 5-15% aromatic compounds — the step above eau de cologne. Lighter and more volatile than eau de parfum, it opens fresh and typically wears 3-5 hours. Many fragrances sold as 'cologne' are actually this strength.
- Eau de parfum (EDP)
- Around 15-20% aromatic compounds, with base notes more prominent and a wear of roughly 4-8 hours. The strongest grade most designer and mainstream lines release.
- Parfum / extrait de parfum
- The most concentrated grade, around 20-30% aromatic compounds (sometimes higher) — the top of the ladder. Richest, longest-lasting, and most expensive; usually dabbed rather than sprayed.
- Eau fraîche
- The lightest common grade, around 1-3% aromatic compounds — mostly water and a touch of scent. Refreshing and very short-lived; meant for a quick splash, not all-day wear.
