How Should Whisky Be Stored?
Store whisky upright, away from direct light and heat, at a reasonably stable room temperature — and finish an open bottle within a year or two for the best experience.
Whisky is far more stable than wine, but a few simple habits keep it tasting its best for longer.
Store bottles upright
Unlike wine, whisky should be stored standing up, not on its side. Whisky's higher ABV can degrade a cork over long periods of constant contact, potentially affecting the seal and letting in unwanted air or, in rare cases, tainting the spirit with cork character.
Keep it out of direct sunlight
UV light can gradually degrade some of the compounds in whisky and affect colour and flavour over long periods. A cupboard, cabinet or shelf out of direct sun is ideal.
Avoid heat and big temperature swings
A stable, moderate room temperature is best. Avoid storing whisky somewhere that gets hot (like near an oven, a sunny windowsill, or an uninsulated garage in summer) or fluctuates significantly, as this can accelerate evaporation and subtly change the spirit over time.
Once opened, don't leave it too long
An opened bottle has more airspace and more oxygen exposure than a sealed one. Whisky doesn't spoil the way food does, but a bottle that's been open for several years, especially if mostly empty, may taste slightly flatter or more oxidised than when first opened. As a rule of thumb, aim to finish an opened bottle within a year or two for the fullest flavour, though it will still be safe to drink well beyond that.
No need to refrigerate
Unlike gin, whisky doesn't benefit from being stored in the freezer or fridge — room temperature is fine for both storage and serving (see "Should whisky be served neat, with water or on ice?" for serving temperature specifically).
