The Note That Makes a Cologne Read 'Masculine' Isn't the One You Think

Musk has a masculine reputation. Our data points the other way. When we read the cited note pyramids of 292 designer fragrances and sorted them by the gender each is sold under, musk in the drydown turned out to be a feminine signal, not a masculine one. The notes that actually code masculine sit somewhere most people never look: the heart.

Which part of the pyramid separates the men’s shelf from the women’s?

The heart, not the base. The part of the pyramid that most cleanly separates the two marketed groups is the middle:

• A herbal (aromatic) heart is the strongest masculine signal: it appears in 35% of men’s fragrances and just 5% of women’s.
• A floral heart is the strongest feminine signal: 77% of women’s fragrances have one, versus 46% of men’s.

Those two families, aromatic and floral, sitting in the heart, separate the men’s shelf from the women’s shelf more cleanly than anything in the opening or the drydown. The opening — the part a shopper judges first — separates the two groups least. The heart separates them most.

Isn’t musk a masculine note?

No, and this is the finding that surprised us most. Musk in the base appears in 35% of women’s fragrances but only 20% of men’s. The soft, clean white musk that anchors a modern floral drydown is, in the data, a feminine-leaning signal. Its “masculine” reputation is marketing memory, not what is actually in the bottles. If you are chasing a masculine drydown, musk is the wrong note to look for.

So what actually codes masculine?

An aromatic-spicy heart over a dry, dark base. The families that lean men’s, by how much more often they appear in men’s pyramids than women’s:

Where	Family	Men’s	Women’s
Heart	Aromatic (herbs, lavender, sage)	35%	5%
Top	Spicy (pepper, cardamom)	34%	14%
Base	Leather	16%	3%
Base	Woody	78%	65%

Leather in the drydown is almost a men’s-only signature (16% vs 3%), and a dry woody base is the quiet backbone of most men’s fragrances. Put simply: a masculine-reading scent is usually a herbal, peppery heart landing on leather and dry wood.

And what codes feminine?

A floral heart over a soft, musky-powdery base:

Where	Family	Women’s	Men’s
Heart	Floral	77%	46%
Top	Floral	28%	4%
Base	Musk	35%	20%
Base	Powdery	6%	1%

Floral does the heavy lifting, and it does it in the heart and the opening. Underneath, the drydown turns soft: musk and powder where the men’s version would turn to leather and wood.

How to use this when you shop

Stop reading the label and start reading the middle and the end of the pyramid. The opening tells you almost nothing about which shelf a fragrance was placed on. If you want a scent that reads a particular way, look at two things: the heart (herbal or floral?) and the drydown (leather-and-wood, or musk-and-powder?). That pair predicts how a fragrance will be perceived far better than the word on the box, and it works no matter which shelf the bottle was placed on.

How we know this

Every figure comes from cited data, not our own noses. We analyzed the 292 designer fragrances in our catalog with a fully resolved top/heart/base pyramid sourced from a brand or authorized retailer (119 sold as men’s, 173 as women’s). Each note is mapped to one of our 14 coarse scent families by its primary family; “family X in the heart” means at least one cited heart note belongs to family X. Gender is recorded exactly as the retailer markets the product and is treated as a marketing label, never a claim about the scent. These are tendencies, not rules: plenty of men’s fragrances carry florals and plenty of women’s carry wood. Where a fragrance’s pyramid cannot be sourced honestly, we leave it out rather than guess, so these numbers describe only what brands and their retailers actually publish.
