Do Spirits Expire?

Sealed spirits don't spoil or expire in the way food does, thanks to their high alcohol content — but flavour can drift subtly over long periods once opened.

Unlike food or even wine, spirits are essentially shelf-stable indefinitely once sealed, because their high alcohol content (typically well above 30% ABV) creates an environment that's inhospitable to the bacteria and microbes responsible for spoilage.

Sealed bottles

A properly sealed, unopened bottle of whisky, gin, vodka or rum stored away from direct sunlight and extreme heat should remain safe and largely unchanged in flavour for many years — decades, even — regardless of any "best by" style date sometimes printed for retail/inventory purposes rather than genuine safety reasons.

Opened bottles

Once opened, a spirit is exposed to more oxygen in the growing airspace above the remaining liquid. Over a long period — think years rather than weeks — this can lead to very gradual flavour drift: brighter, more volatile notes (especially citrus and floral ones) fading first, sometimes leaving a flatter or duller character. This is a quality change, not a safety issue — an old opened bottle won't make you sick, it may just taste slightly less vibrant than when first opened.

Exceptions: cream and egg-based liqueurs

Cream-based liqueurs and other dairy or egg-containing products are the main exception — these behave more like a perishable food product and typically carry a genuine "best before" or "use by" date that should be respected, unlike standard spirits.

The practical takeaway

For almost all standard spirits, there's no need to worry about a bottle "going off" — the bigger consideration is simply that flavour is at its best relatively soon after opening, so it's worth working through opened bottles at a reasonable pace rather than treating spirits as truly indefinite once air has gotten in.
