We went looking for global aged whisk(e)y stock levels. No world number existed. So we are building one.
Only a few entries carry an official count. Everything else is derived, disclosed by producers, or estimated. The tier tells you which, and the whole point of this page is that the uncertainty stays visible.
| Country | Central | Range | Evidence tier | Basis |
|---|---|---|---|---|
| United States | 25m | 23–27m | Official aggregate, converted | Converted from a national aggregate: ~1.5 billion proof gallons of American whiskey in inventory at end-2024, at 55–66 proof gallons per filled barrel (DISCUS; Kentucky Distillers’ Association). |
| Scotland | 22m | 21–23m | Officially counted | Physical cask count published by the industry body, the Scotch Whisky Association. |
| Ireland | 4.5m | 4–5m | Private-report estimate | The LYQD Irish Whiskey Supply Report 2026 (analysis Oct 2025, by independent industry analyst Martin Purvis), corroborated by two lines that share none of its inputs: Drinks Ireland’s published 3.1m casks (2020) rolled forward on flow arithmetic, and a producer bottom-up across Irish Distillers, Great Northern, Bushmills and Waterford bracketing 3.8–4.2m. |
| Canada | 4.3m | 3.9–5.2m | Published partial stock | Published producer floor of 3.9m across four sites, plus an itemised allowance disciplined by a withdrawal-times-residence model. |
| Japan | 2.3m | 1.3–4m | Published partial stock | One reported site (~600,000 casks at Suntory's Ōmi Aging Cellar); national total modelled from NTA throughput data and stated assumptions because no usable national maturing-stock aggregate is published. |
| China | 0.75m | 0.6–1m | Published partial stock | Laizhou's listed parent reported nearly 600,000 filled casks at end-2025, scaled by its trade-reported ~80% share of production. |
| India | 0.5m | 0.3–0.9m | Published partial stock | Investor disclosures plus a producer bottom-up across 20+ malt distilleries, bracketing the Indian Malt Whisky Association's 300,000+ barrel figure. |
| Continental Europe | 0.4m | 0.25–0.55m | Published partial stock | Bottom-up across published stock: DYC trade-reported at 170,000 aging casks, High Coast 20,000+, St. Kilian ~10,500, plus a flow model on the INAO's official French production series. |
| Taiwan | 0.15m | 0.1–0.25m | No published figure | Withdrawal-times-residence model on Kavalan's 10m+ bottles a year, plus a reported ~4,500-cask floor at Nantou; capacity is not counted as stock. |
| South Africa | 0.15m | 0.1–0.2m | Published partial stock | James Sedgwick, Africa's major whisky distillery, described as holding 150,000 casks across five warehouses (2018). |
| Rest of world | 0.15m | 0.1–0.3m | No published figure | Order-of-magnitude allowance for everyone not listed above. |
| Australia & Tasmania | 0.1m | 0.04–0.2m | Published partial stock | Lark alone reported 2.5m litres under maturation at 30 June 2025; the national estimate adds a broad allowance across a fragmented industry. |
| England & Wales | 0.05m | 0.05–0.07m | Officially counted | Trade-body forecast of casks maturing, published by the English Whisky Guild. |
| World total | 60.4m | 55–68m | Sum of the entries above. The low case is every regional low at once, not a confidence interval. | |
The estimate is built from official aggregates, producer disclosures, and stated-assumption models, with the arithmetic published. Where a figure is estimated rather than counted, it is asterisked, ranged and labelled as such.
Explore seventeen woods through the Irish whiskeys they shape. Take an American oak cask apart, then discover what bourbon, sherry, port and other previous fills bring to its next life.
Seven interactive still deconstructions so far. Midleton, Glenmorangie's giraffe neck, Bruichladdich's Lomond still, Old Pulteney's still with no head, The Macallan's curiously small still, The Dalmore's water-jacketed still and Woodford Reserve's three-pot train so far: rotate the copper, deconstruct it part by part, and read each distillery's history with every claim sourced.
If you hold better data, we would rather publish your number than our estimate.
Write to hello@stillbound.ai with the figure and its basis. Corrections are logged and dated on the evidence page.
