Fragrance notes explained: top, heart and base

Every fragrance description you read is built around three layers of notes. Understanding them is the difference between buying a bottle you love and buying one that smelled wonderful for ten minutes.

Top notes: the first ten minutes Top notes are the smallest, lightest molecules in the blend, so they evaporate first. Citrus — bergamot, lemon, grapefruit — along with light herbs and aquatic accords, live here. They are the reason a fragrance feels bright on the blotter. They are also the reason a shop sample can mislead you: within fifteen minutes, most of what you first smelled has gone.

Heart notes: the actual character The heart, or middle, is what the fragrance is. Rose, jasmine, iris, lavender, spices such as cinnamon and cardamom, and fruity accords sit in this layer. They emerge as the top notes fade and typically hold for a few hours. If you want to know whether you will enjoy wearing something all day, judge it at the one-hour mark, not at first spray.

Base notes: what lingers Base notes are the heaviest molecules and the slowest to leave: woods such as cedar and sandalwood, vanilla, amber, musks, patchouli, oud and leather. They anchor the composition, give it longevity, and are what other people notice on a scarf the next morning. A base-heavy fragrance will feel richer and last longer; a citrus-forward one will feel fresher and fade faster.

Concentration changes everything The same name can be sold as eau de cologne, eau de toilette, eau de parfum, or parfum/extrait. The difference is the proportion of fragrance oil to alcohol, and it rises in that order. A higher concentration usually means more projection, longer wear, and a heavier emphasis on the base. It also means a higher price, which is why comparing an eau de toilette price against an eau de parfum price is comparing two different products. Our product pages list the concentration and size so you can line up like for like.

Families, briefly Most fragrances sit in one of a handful of families. Florals are built around single blooms or bouquets. Orientals, sometimes called ambers, lean on resins, vanilla and spice. Woody fragrances centre on cedar, vetiver and sandalwood. Fresh fragrances cover citrus, green and aquatic styles. Chypres combine a citrus opening with a mossy, earthy base. Knowing which family you gravitate towards narrows thousands of bottles down to a manageable shortlist far faster than reading individual reviews.

Why the same bottle smells different on you Skin chemistry, hydration and even diet shift how notes develop. Warmer, oilier skin tends to project more and burn through top notes faster. Dry skin holds fragrance less well, which is why applying to moisturised skin makes a noticeable difference to longevity. This is also why a blind buy based on a description alone is a gamble, however precise the note list.

How to use notes when shopping Read the pyramid, identify the heart and base, and ask whether those are materials you already enjoy. If three fragrances you love all list iris or vetiver, that is your signal. Then compare prices on the specific size and concentration you want — the [perfume department](/category/perfume) lists live prices across tracked UK retailers, and houses such as [Tom Ford](/brand/tom-ford) and [Jean Paul Gaultier](/brand/jean-paul-gaultier) have wide ranges where the same note families appear at very different price points.
