Age statements explained: what the number on the bottle really means
What an age statement means, why NAS whiskies exist, and whether older whisky is really better.
- An age statement is the age of the youngest whisky in the bottle.
- Age is time spent in a cask. Whisky does not age in the bottle.
- No age statement (NAS) does not mean young or poor. It means the producer chose not to say.
- Older is not automatically better. Too long in a cask can make whisky taste woody.
- Climate and cask size change how fast whisky matures, so age alone is not a fair comparison.
What an age statement means
When a label says 12 years, it means every drop of whisky in the bottle spent at least 12 years in a cask. The bottle can also contain older whisky, but the number on the label must be the age of the youngest.
That matters most for blends. A 12-year-old blend might be made of dozens of whiskies. Some may be 12, and others may be 20 or more. The label shows only the youngest.
It is also important to remember that age is time in the cask. Once whisky is bottled, it stops ageing. A bottle of 12-year-old whisky that has sat on a shelf for 30 years is still a 12-year-old whisky.
Minimum age rules by country
What is NAS whisky?
NAS stands for no age statement. The label does not say how old the whisky is. NAS whiskies have become common over the last few decades, for a few reasons:
- Stock. Demand grew faster than distilleries could age whisky, so brands used younger stock alongside older casks.
- Flavour. Some producers would rather focus on the taste and the casks used than on a number.
- Creativity. It gives blenders freedom to mix whiskies of different ages to hit a flavour target.
NAS is not a sign of poor quality. Well-regarded examples include Ardbeg Uigeadail, Laphroaig Quarter Cask and Nikka From The Barrel. The thing to watch is price: pay for the taste and the producer's reputation, not for the lack of a number.
Vintage and bottling dates
Some labels give a year instead of an age. A vintage or distillation year, such as 1998, tells you when the spirit was made. A bottling year tells you when it was put into bottle. Subtract one from the other and you get the age, so a whisky distilled in 1998 and bottled in 2018 is 20 years old.
Is older whisky better?
Not always. Age brings smoothness, depth and complexity, but it also brings more wood. Whisky left in a cask for too long can taste bitter and woody, and lose the character of the spirit. Younger whisky can be fresh, vibrant and full of grain and fruit.
Age also does not travel at the same speed everywhere. Whisky matures faster in hot climates such as Kentucky, India and Taiwan, and in small casks, so a five-year-old from one place can be as developed as a 12-year-old from another.
Price tends to rise with age because older whisky costs more to make: more is lost to evaporation (the angels' share), the casks take up space for longer, and there is less of it.
How to use age statements when you buy
- Compare within a distillery. Try a 10, a 12 and an 18 from the same producer to hear what age does for that house style. Our reviews of Glenfiddich 12 and Ardbeg 10 are a good place to start.
- Do not skip NAS. Some of the best bottles for the price have no age statement.
- Read the rest of the label. Cask type, ABV and finish say as much about flavour as age does. See how to read a whisky label.
- Taste before you pay a premium. A big jump in price for a few extra years is not always a big jump in enjoyment.
Age statements: quick answers
What does 12 year old mean on a whisky bottle?
It means the youngest whisky in the bottle spent at least 12 years in a cask. Older whisky may also be in the bottle.
Is NAS whisky young?
Not necessarily. NAS whiskies can include young whisky, but they can also include older whisky, and some are made entirely from carefully chosen casks. Judge by taste rather than by the missing number.
Does whisky age in the bottle?
No. Whisky only ages in the cask. Once it is bottled, its age is fixed. An open bottle changes slowly through contact with air, but that is not ageing.
Why is older whisky so expensive?
Older whisky costs more to produce. Some evaporates every year, casks and warehouses are tied up for decades, and there is limited stock. Collectors and demand push prices up further.
Can a whisky be older than the label says?
Yes. A blend may contain whiskies older than the age on the label, because the label always shows the youngest component.
