President Donald Trump’s decision to remove a 10% tax on Scotch whiskey sales in the US has brought relief to the beleaguered sector – and may provide a much-needed boost to a niche corner of the industry: premium cask investing.
Cask investing involves buying an oak barrel full of Scotch – either just after it has been aerated or aged – and allowing its contents to mature over a period of 10 to 20 years, before selling it.
Casks are often traded in the industry through individual contracts between blenders and distillers, often involving an exchange of casks in exchange for money, or through Scotch whiskey brokers. Individual investors can also purchase casks of Scotch whiskey freshly distilled or matured, either for personal use or as a speculative bet for the purpose of selling at a profit in the secondary markets.
Like other collectibles, such as fine art, rare watches and classic cars, cask investing is a high-risk, speculative, long-term bet on primarily unregulated, illiquid assets. Although generally considered a hedge against inflation, the value of such assets is entirely dependent on secondary market demand.
John Kennedy, managing director at Decant Index – a trading platform for investors to buy and sell other collectibles, including premium whiskey – said Trump’s decision to scrap the import tax could boost outflow rates for cask investors.
The US is the largest export market for Scotch, worth about £933 million ($1.27 billion) by 2025, according to the Scotch Whiskey Association, the industry’s trade body.
Kennedy said removing tariffs would reduce friction for importers, distributors and independent bottlers sourcing stock from Scotland, while also strengthening long-term confidence in the industry as a whole.
“The biggest impact is likely to be felt at the end of the market,” he said. “American consumers have historically shown a strong desire for aged, collected and luxury Scotch whisky.”
For cask investors, this means the development of a long-term outlet, according to Kennedy.
“Higher demand for mature stock from the world’s largest whiskey market should increase mature cask revenue and price support over time, especially for well-known distilleries with strong international demand,” he told CNBC via email.
‘Water of life’
Trump’s decision, announced on May 1 following King Charles III’s visit to the US, will apply to all whiskey prices, including Irish whiskey, the UK government confirmed to CNBC earlier this month.
Mark Kent, CEO of the Scotch Whiskey Association, said the deal was “very encouraging” for the industry.
Hard data on the cask investment sector is hard to come by, but data from Whiskeystats shows that the wider Scotch market has lost around a third of its value in three hot years.
Its monthly market-weighted index of the 500 best-selling whiskeys in Scotland fell 29.74% during the period, while the benchmark ended April about 5.2% lower.
But there are signs of improved investor interest.
Shares in the UK drinks behemoth Diageo – whose brands include blended whiskeys Johnnie Walker and Bell and single malts Talisker and Cragganmore – are in the spotlight following Trump’s decision.
Diageo has fallen almost 28% in the past year after the White House’s ‘Independence Day’ tariffs hit most UK exports to the US, including spirits, with a 10% tariff.
Diageo.
Kennedy said entry-level investment can start from around £2,000 for small spirits from emerging estates – while casks from well-known names such as Macallan, Dalmore or Springbank can trade for “six figures” depending on vintage, age and cask type.
He said a more accessible US market as a result of the price change would increase demand for US whiskey – uisge beatha in Scottish Gaelic, or “water of life” – and support higher prices over time.
“In the longer term, we expect this to support continued demand for old stock, individual bottlings and collective releases, all of which are positive indicators for the cask investment sector.”
Liquid gold?
But like other collectible markets, buyers face a number of risks in this category of off-piste goods.
Scotch whiskey casks are not traded as commodities on the central trade and are not regulated by the UK’s Financial Conduct Authority.
Each year, about 2% of the air naturally evaporates during the maturation process in porous oak barrels – a loss known as the “angel’s share.” Over time, the effect can reduce the strength of the alcohol to less than 40%, thus robbing it of its legal right to be called Scotch whisky.
There are also strict rules governing the storage of mortgaged property and proprietary properties.
“Unlike publicly traded markets, casks don’t sell quickly and price visibility can vary greatly between distilleries and vintages,” Kennedy said.
He added that rare availability and maturity have historically supported value creation in the whiskey market. “This remains a specialist, long-term alternative asset and investors should approach it carefully. The biggest risks are around provenance, ownership structure, storage, insurance and unrealistic expectations of returns.”
The Scotch Whiskey Association did not respond to CNBC’s request for comment.
However, the trade body warns on its website that prospective investors in casks should be aware of the risks involved, “both in terms of the potential value of their investment and the chances of selling it.”
“There is no regulated market for mature or aged Scotch Whisky, there is no officially published list of buying and selling prices for casks from different distilleries or for different years and there is no established method of sale,” he said.
It also warns consumers about the risk of fraud in the cask investment market.
