Is 18 year old whisky worth it?

How much more an 18 year old costs than the 12 from the same distillery, using current UK prices, and when the step up makes sense for the drinker.

Published Updated

Across the 8 distilleries where we priced both the official 12 and 18 Year Old on 14 October 2026, the 18 cost between 1.8 and 4.8 times the 12, with a typical step of 2.6 times. Whether six more years in oak are worth that is your call; here is what the step looks like, distillery by distillery.

This guide links to retailers. Some links may earn us a commission; picks are based on the price data and the criteria below.

How we compared

We took official, non-limited 12 and 18 Year Old bottlings from the same distillery: full-size bottles, in stock, with a current price at one of the UK retailers we check on 14 October 2026. Names including “cask strength”, “edition”, a vintage year or similar were excluded, so each pair sits in the same range. The ratio is the lowest in-stock offer for the 18 divided by the lowest for the 12. Loch Fyne Whiskies and The Whisky Shop share an owner, so we count them as one retailer.

We compare prices, not flavour. We have not tasted these bottles for this guide, and nothing below is a verdict on which whisky is better.

The price step, distillery by distillery

The ratios below are from our 14 October 2026 check. The live prices render with their retailer and check time, so where the ratio looks stale, trust the figures.

Where a distillery’s 12 and 18 are stocked by several shops, the bottle pages also show how much the ratio moves between retailers.

What the extra years change

Six more years means six more years of cask, warehouse and evaporation: some of the whisky is lost to the air each year, which is one reason older stock costs more. Whiskipedia’s guide to the angel’s share explains the loss, and its whisky maturation guide covers what the cask does over time. Older stock is also scarcer by definition. What those years do to flavour is a matter of taste, and sellers’ descriptions of older whisky as smoother are taste claims we cannot test, so we do not make them.

The middle step: 15 year olds

There is a rung between the 12 and the 18. At the same check, across 9 distilleries with an official 12 and 15 both priced, the 15 cost between 1.3 and 2.2 times the 12, typically 1.8 times. Examples: GlenAllachie 15 Year Old (£67.95 at Hard To Find Whisky), The Glenlivet 15 Year Old (£53.95 at Master of Malt), Tamdhu 15 Year Old Sherry Cask Matured (£90.95 at The Whisky Barrel) and Bowmore 15 Year Old (£73.95 at Master of Malt).

When the step up makes sense

The case for the 18 is strongest when you already know and like the distillery’s 12: you are buying more time in wood from the same house, which is the most predictable upgrade there is. It also works as a gift for an adult who already drinks the 12, since the comparison is built in. One practical point from our data: most of the 18s cost enough on their own to qualify for free standard delivery at the shops we check, while most of the 12s do not, so the delivered gap runs slightly narrower than the shelf gap.

The case against is in the ratios above. Where the step is three times or more, the distillery’s 15 narrows it, and a different cask at 12 year old money, a sherry finish say, changes the glass more than it changes the bank balance. If the budget is fixed, the 12 year old, 15 year old and 18 year old selections show every bottle we track at each age.

How we chose: check date and coverage

We compared in-stock offers from Abbey Whisky, DrinkSupermarket.com, Hard To Find Whisky, Loch Fyne Whiskies, Milroy’s of Soho, The Whisky Shop, Tyndrum Whisky and Whisky Me in our October 2026 catalogue checks. Loch Fyne Whiskies and The Whisky Shop count as one owner. Prices and stock change; the live table on each bottle page is current, and the retailer’s checkout price is the one that counts.

Questions

Why does 18 year old whisky cost more to make than 12 year old?
Because it spends six more years in cask. Evaporation (the angels’ share) removes roughly 2% of spirit volume per year, so after 18 years a cask holds around a tenth less whisky than it did at 12. Those extra six years also tie up bonded warehouse space, insurance, and working capital before a bottle can be sold. See why old whisky is expensive.
Does the age on the label mean every drop is that old?
It means the youngest whisky in the bottle is at least that age (Scotch Whisky Regulations 2009, regulation 12). Older whisky may also be in the mix. And whisky does not keep ageing in the bottle: a 12 year old kept in a cabinet for 10 years is still a 12 year old.
What does six extra years in the cask do to whisky flavour?
Extra maturation increases the extraction of oak compounds, including vanillin, tannins, and wood sugars, from the cask into the spirit. Subtler distillery character often yields to deeper wood influence, dried fruit, or spice notes, particularly in European oak sherry casks. The charred cask wall absorbs sulphury new-make notes and slow oxidation through the wood softens the spirit, though too long in an active cask can bring dry, woody bitterness (Whiskipedia on maturation).
Does 15-year-old whisky bridge the gap between 12 and 18?
At distilleries that make all three, yes. Glenfiddich sells a 12, 15 and 18 Year Old, and its 15 Year Old is married in a solera vat after maturing in sherry, bourbon and new oak casks. Three extra years give more wood influence than a 12, and at about 2% a year a cask loses roughly another 6% of its contents, against about 11% for the six years to 18.
