How to Store Perfume Decants, and Do They Expire?

A decant will happily last for years, or it will turn in a few months. The difference is almost entirely down to where you keep it. Perfume does not really have an expiry date in the way food does, but it does have three enemies, and most people store their decants next to all three.

The three things that ruin perfume

Heat is the worst of them. Warmth accelerates the chemical reactions that break down aromatic molecules, and a bathroom shelf that swings from cold to steam twice a day is close to the worst place in a home. A bedroom drawer is better than a bathroom cabinet by a wide margin.

Light, especially direct sun, does the same work more slowly and also discolours the juice. This is why serious houses ship in coloured or boxed glass. If your decant came in a clear vial, keep it in a drawer or its box rather than on a windowsill.

Air is the quiet one. Every spray pulls air into the vial, and oxygen gradually oxidises the top notes first. That is why a half-empty decant smells slightly different from a fresh one: the citrus and green notes go before the base ever moves.

How long a decant actually lasts

Stored somewhere cool, dark and stable, expect three to five years of very little change. Some things last far longer and some are noticeably shorter.

• Citrus, aromatic and green compositions are the most fragile. Their brightness is carried by the most volatile molecules, and those are the first to go. Use these within a year or two.
• Oud, resin, amber, tobacco and heavy woods are the most durable, and a number of them genuinely improve with a year or two of rest as the sharper edges settle.
• Naturals and extraits vary. Real materials can shift more than synthetics, which is part of their character rather than a fault.

How to tell when one has turned

The reliable sign is the opening, not the drydown. A turned perfume smells sour, faintly metallic or like old cooking oil in the first thirty seconds, then often settles into something close to normal. Colour darkening on its own is not proof of anything, since many naturals darken with age while smelling perfect.

Practical storage, briefly

• Keep decants upright, so the juice is not sitting against the seal.
• A drawer, a box or a cupboard away from a radiator beats any shelf on display.
• Stable temperature matters more than cold temperature. A fridge is unnecessary and the repeated in-and-out swings do more harm than the cool does good.
• Leave the juice in the vial it arrived in. Every transfer is another dose of oxygen.
• If you own the full bottle as well, use the decant for travel and keep the bottle boxed at home.

Why decant size and storage are the same decision

If a fragrance is bright and citrus-led, a smaller decant you will finish quickly makes more sense than a large one that slowly fades in a drawer. If it is an oud or a resinous extrait, a 10ml will still be excellent in three years. Working out how long a size will last you is covered in how many sprays are in a decant.

Everything here is poured to order from sealed bottles rather than sitting pre-filled on a shelf, which means your decant starts its life on the day you order it. Browse the full range of samples and decants.
