Value Analysis

Decant Calculator

Work out the cost per milliliter of a bottle you own or are weighing up, and roughly how many wears it holds. The arithmetic is exact; the wears depend on the sprayer (modeled).

Accord Builder

Build your own fragrance accords by selecting notes from each tier. The analysis updates as you choose - a teaching model of how notes combine, not a formula.

Olfactory Fatigue Timer

Pace a smelling session. The nose adapts to what it keeps smelling, so many perfumers rest between rounds; this timer makes the pause deliberate. The lengths are common practice, not a measured rule.

15:00
Ready to sample
Why Rest Your Nose?

Smell adapts: after a while with the same smell, the nose registers less of it (olfactory adaptation), and the fine differences between fragrances go first. Many evaluators work in short rounds with a few fragrances each and rest in between. How long a rest needs to be varies; the presets are common choices, not a measured threshold.

Reset Techniques
  • Coffee beans: a common ritual; whether they help is debated
  • Your own skin: many use the familiar smell of the inner elbow as a neutral reference
  • Fresh air: step outside for a few minutes
  • Wool fabric: some keep unscented wool to hand as a neutral smell

Bleu de Chanel
Eau de Parfum
2014 · Jacques Polge
BeginnerCrowd-Pleaser

A modern masculine reference point. Fresh, woody, widely liked without being boring. Works in most situations — office, date, gym, funeral. If you own one fragrance, this is defensible. Iso E Super provides that “can’t quite place it” magnetism.

A widely worn men’s fragrance. Ambroxan-forward, fresh-spicy, projects hard. Polarizing among enthusiasts but popular with most others. If compliments are your goal, this is a dependable choice.

2001 · Jacques Polge

The modern feminine classic. Fresh, floral, slightly spicy — sophisticated without being matronly. The patchouli base gives it depth; the orange keeps it bright. Two decades on, still a reference point for many feminine fragrances.

2006 · Maurice Roucel
BeginnerCrowd-Pleaser

A well-loved budget classic. Fresh, aquatic, clean — and made by Maurice Roucel, who also created Musc Ravageur for Frédéric Malle. A reminder that price doesn’t determine quality. A good summer scent. Inoffensive. Money well spent.

Mediterranean freshness in a bottle. Neroli, citrus, amber — clean and slightly sweet. Created by Alberto Morillas, the nose behind Acqua di Giò. It smells better than its modest price suggests. Office-appropriate, date-worthy, genuinely versatile.

Zara’s hidden gem. Sweet, slightly boozy, reminiscent of Paco Rabanne 1 Million. The caramel-cinnamon opening settles into a warm amber base. Legitimately good — not “good for the price,” just good. Club-ready.

Woody, slightly smoky, undeniably fresh. Pine needles and bergamot open into a vanilla-sandalwood base. One of the fragrances that made Byredo’s name. Easy to wear, easy to remember. The scent of expensive hotels and people who read literary fiction.

The smell of Brooklyn, SoHo, and many an upscale hotel lobby. Cardamom, violet, sandalwood, leather — smoky, androgynous, ubiquitous. So popular it’s almost cliché. But it became cliché because it’s genuinely excellent. A modern signature scent.

Christopher Sheldrake

Named for the hot Saharan wind. Tobacco, hay, honey, incense — dry sweetness without cloying. Christopher Sheldrake created liquid North Africa. Coumarin and benzoin provide the backbone; tobacco leaf provides the soul. A favorite oriental of ours.

Medieval cathedral in a bottle. Frankincense, myrrh, and cold stone. Part of the Incense Series — Comme des Garçons’ meditation on sacred spaces. Not conventionally “wearable” but utterly transporting. Close your eyes and you’re in a 12th-century nave. Art perfumery at its best, to our nose.

Animalic florals done fearlessly. Jasmine sambac, tuberose, and civet create something almost uncomfortably carnal. Not for the timid. Liz Moores crafted a fragrance that smells like desire itself. A favorite modern animalic of ours. Polarizing, unforgettable, magnificent.
