Scotland’s warehouses are holding the equivalent of around 12 billion bottles of whisky as producers contend with falling exports, weakening consumer demand and rising costs.
An estimated 22 million casks are currently maturing across the country, according to the Scotch Whisky Association.
That is equivalent to around 12 billion 70cl bottles and represents an increase from the figure of more than 20 million casks widely cited earlier in the decade.
The enormous stockpile is spread across bonded warehouses from the Highlands and islands to the central belt, including large storage facilities in Fife and Clackmannanshire.
Not all of the spirit is ready to be sold. Scotch whisky must mature in oak casks in Scotland for at least three years, while many premium expressions are stored for a decade or longer.
However, the rising volume illustrates the challenge facing an industry which increased production and invested heavily in new distilleries during a period of booming international demand.
The Financial Times reports that the sector is now experiencing its most difficult downturn since the 1980s, with some producers reducing or temporarily pausing production as demand fails to keep pace with supply.
Holyrood Distillery in Edinburgh is among the smaller producers reported to have paused production from its copper stills for the foreseeable future.
Independent distilleries are considered particularly exposed because they have fewer established brands and less financial capacity to store whisky for years while waiting for market conditions to improve.
Larger drinks companies have also cut output as they attempt to manage stock levels and protect prices.
The downturn follows several years of slowing international sales. Scotch whisky exports were worth £5.3 billion in 2025, down 1.8 per cent from the previous year, while the number of bottles exported fell by 4.3 per cent to 1.34 billion.
Exports to the United States, the industry’s most valuable overseas market, dropped by four per cent in value to £933 million. Volumes fell more sharply, declining by 9.2 per cent to the equivalent of 120 million bottles.
Single malt exports were particularly affected by weaker spending on premium products, falling by six per cent in value during 2025.
Industry leaders have blamed a combination of economic uncertainty, changing drinking habits, international trade disruption and increased domestic taxes and regulation.
Scotch Whisky Association chief executive Mark Kent said earlier this year that companies were experiencing “strain not felt for decades”.
The organisation warned that some distilleries had halted or reduced production, jobs had been lost across the wider supply chain and more businesses could close without government support.
Despite the difficulties, the whisky industry remains one of Scotland’s most valuable economic assets.
There were 154 operating Scotch whisky distilleries in May 2026, supporting more than 41,000 jobs in Scotland. The sector generates an estimated £5.3 billion for the Scottish economy and accounts for almost three-quarters of the country’s food and drink exports.
There are also signs of potential recovery in overseas markets. A zero-tariff agreement with the United States came into effect in July, removing the 10 per cent charge which had been imposed on Scotch whisky.
The UK’s trade agreement with India has also reduced the tariff on Scotch from 150 per cent to 75 per cent. It is due to fall progressively to 40 per cent over the next decade.
India was already the biggest market for Scotch by volume in 2025, importing the equivalent of 220 million bottles. It also became the industry’s third-most valuable export destination after sales increased by 15 per cent to £286 million.
Ministers and industry leaders hope the tariff reduction will make Scotch more competitive among India’s expanding middle class and provide a new market for the vast quantities currently ageing in Scotland’s warehouses.
