Slane was famous for rock music long before whiskey appeared under its name. Since Henry Mountcharles staged the first Slane concert in 1981, the grounds of Slane Castle have hosted U2, Bruce Springsteen, David Bowie, Queen, the Rolling Stones and some of the biggest acts in the world.
But the Conyngham family needed businesses capable of supporting a large historic estate throughout the year. Alex Conyngham explained the thinking to The Spirits Business in June 2018: His father, he said, had effectively saved the estate by using the front garden for rock concerts, but there was not a concert every year. The family needed something more consistent which could make commercial use of the Slane name, and whiskey appeared an obvious fit, with all its rock and roll connotations – good and bad – made perfect sense. Slane estate farm grew barley, Alex had previously worked as a Jameson brand ambassador in Australia, and Irish whiskey was entering what would become an extraordinary period of international growth.
The family did not, however, start by building a distillery. That would have required millions of euro and, even once production began, a wait of at least three years before any spirit could legally become Irish whiskey. Instead, they went to John Teeling’s Cooley Distillery.
Slane Castle Whiskey launched in 2009, including promotion around that year’s Oasis concert at Slane. The business gradually expanded into Ireland and the US. By 2012 Henry Mountcharles said more than 7,000 cases had been sold and the whiskey had picked up competition awards. The model was straightforward. The Conynghams owned and developed the Slane brand; Cooley supplied the whiskey. Then Cooley was sold.
Beam bought the independent Irish distiller at the end of 2011. Irish whiskey was booming and Beam concluded that the stocks sitting in Cooley’s warehouses were going to be needed for its own brands, including Kilbeggan, Tyrconnell, Connemara and Greenore, and so third-party customers suddenly became less important. Slane was one such customer. In April 2012, Henry described the news of the end of supply to the Irish Independent as feeling as though the business had been “cut off at the knees”. The timing was particularly painful. According to reporting at the time, Slane had been working on further international distribution when its supply disappeared. Its remaining stocks became scarce enough that Henry said the retail price had moved from around €25 towards €50. The Conynghams had learned the fundamental weakness of being a sourced-whiskey brand; they could own the name, packaging and customer relationships., they could spend money creating demand – but somebody else owned the whiskey. This was a tap that could be switched off.
Losing Cooley turned the family’s idea of eventually distilling at Slane into something much more urgent. The difficulty was that a proper distillery required considerably more capital than simply sourcing and bottling whiskey.
Enter Brown-Forman. On 2 June 2015, the Kentucky company behind Jack Daniel’s and Woodford Reserve announced that it had purchased all the shares in Slane Castle Irish Whiskey Limited. It also committed approximately $50 million to a new distillery and visitor experience at Slane. It was an important acquisition for Brown-Forman. When construction began that September, the company described Slane as the first distillery it had built outside the United States.
But buying Slane and building a distillery did not solve the immediate whiskey problem for the Slane brand, so Brown-Forman therefore announced from the outset that the relaunched Slane would initially contain mature whiskey purchased from other Irish distilleries. That stock would be finished and blended to Slane’s requirements while whiskey made at the new distillery was laid down to mature. There is an irony here; the whole reason Slane wanted a distillery was its experience of depending on somebody else’s whiskey. Yet it first had to become a sourced-whiskey business again in order to survive long enough to become self-sufficient. This is common in the category but the downside of selling a sourced brand under your distillery or placename brand is that nobody knows when you finally do launch your own whiskey, or if they do, they realise they have been buying whiskey from you on false pretences. Most brands in the Irish whiskey category obviously do not care as the majority has been and is still enthusiastically sourcing stock.
Alex Conyngham told The Spirits Business in August 2023 that the stocks bought for the early Brown-Forman-era Slane included mature malt and grain whiskey, some already significantly older than the three-year legal minimum. The Brown-Forman partnership also gave Slane unusual access to casks.
Meanwhile, the new Slane plant’s pot stills could make malt and pot-still spirit, while continuous distillation provided the grain whiskey required for a large blended brand. Brown-Forman’s original plans envisaged potential output equivalent to more than 600,000 cases a year.
Production was fully running by 2018, meaning that after six years of uncertainty following the Cooley cutoff, Slane finally controlled the means of making its own whiskey.
That did not mean Brown-Forman expected an instant financial return; CEO Lawson Whiting was strikingly open about Slane when interviewed by The Spirits Business in July 2019.
He said that the strategy was deliberately slow. Brown-Forman wanted Slane in the right bars and restaurants rather than simply pushing cases into supermarkets. Whiting said the company expected to “lose millions of dollars a year on Slane” while establishing it. He described it as a “slow build”. Brown-Forman had done something similar with Woodford Reserve, patiently building the bourbon before it eventually became a major international premium whiskey. That was the model Slane hoped to emulate.
But by 2024 it was clear just how far there was to go. Alex Conyngham told Just Drinks in April 2024 that Slane was selling approximately 50,000 cases globally, almost all of it the standard Triple Casked blend, but that his ambition remained one million cases.
“I’m hoping that we can emulate the likes of what Woodford Reserve have done,” he said, while acknowledging that it would take “hard graft to get there”. That is a huge gap: about 50,000 cases against a long-term ambition of one million.
The broader Irish whiskey category, meanwhile, had become enormous. Irish Whiskey Association data show 16.15 million nine-litre cases were sold globally in 2024, of which 5.47 million went to the US. The majority of that, it should be noted, is just Jameson.
Reporting on company accounts in April 2026, the Irish Independent said Slane Castle Irish Whiskey made a loss of more than €4.98 million.
In May 2026 Brown-Forman stopped producing whiskey at Slane. Its explanation was not that Slane was being discontinued, but that production planning had been adjusted to market conditions and that the company had a “robust supply of maturing whiskey”, sufficient to maintain supply of Slane to customers. Brown-Forman did not provide an official restart date. Alan Buckley, who had been Slane’s site leader for production, quality and wood management, was rather more specific when announcing his redundancy on LinkedIn. He said production had been paused “for the next number of years”.
The plant can produce up to one million litres of pure alcohol annually, according to The Spirits Business, so this was not simply cancelling a few production days. Brown-Forman had spent tens of millions creating an Irish production base designed to eliminate Slane’s dependence on other distillers. Eight years after production began, it concluded that no more new spirit was required for the foreseeable future. But this is not just a Slane problem, or an Irish problem, it is a global spirits problem.
On its 2 September 2026 earnings call, Lawson Whiting disclosed what has happened to another part of Brown-Forman’s whiskey business: used barrel sales. Two years ago Brown-Forman was generating more than $100 million a year selling used barrels. Last year that had fallen to approximately $30 million, and Whiting said another significant reduction was expected. Demand from Scotch and Irish whiskey producers is far below the extraordinary levels seen a couple of years ago. Used American whiskey barrels are a basic input for Scotch and Irish whiskey maturation. If distillers are making substantially less new spirit, they need substantially fewer emptied bourbon and Tennessee whiskey casks.
Whiting went further when discussing American whiskey. He said many producers had overproduced during the boom years. New barrel fills had fallen by around 30% in calendar 2025 and he expected a further very large reduction in 2026, although that latter figure was his own expectation rather than reported industry data.
That makes Slane’s shutdown look less like an isolated event and more like an extreme example of a much wider correction.
Brown-Forman’s CFO Jim Peters made the company’s position still clearer at the Barclays Global Consumer Conference on 9 September. Brown-Forman, he said, had invested heavily in production facilities during the boom. That investment programme was largely finished and, in the current market, “we may have some more capacity than we need”. That statement wasn’t specifically about Slane. It referred to Brown-Forman’s global production system, but it describes precisely the situation visible at Slane. Peters told Barclays that Brown-Forman generally preferred to smooth production rather than impose significant distillery downtime, because stopping and starting plants is expensive. Slane has nevertheless been stopped completely.
It is reasonable to infer — while clearly recognising this is an inference rather than something Brown-Forman has said — that the supply-demand imbalance at Slane was large enough that simply reducing shifts or slowing production did not solve it. The whiskey itself is becoming more expensive to carry.
Brown-Forman says whiskey made during the high-inflation years around Covid is now moving through its inventory system. Grain, barrels, energy and other inputs were unusually expensive when that spirit was made. At Barclays on 9 September, CFO Jim Peters said this higher-cost whiskey will create a 100 to 150 basis-point headwind to Brown-Forman’s gross margin over the next couple of years. Again, that is a group figure, not a Slane figure, but it underlines why distillers now care so much about matching production to realistic demand. Making whiskey today creates a cost that can sit on the balance sheet for years before the resulting bottle generates revenue.
Brown-Forman’s consolidated balance sheet shows just how large that machine has become. At 31 July 2026, the company held $1.539 billion of barreled whiskey, $516 million of finished goods, $424 million of work in progress and $95 million of raw materials and supplies — total inventories of $2.574 billion.
So Slane, owned by a global drinks giant, is closed, but Irish whiskey as a category actually performed better than most spirits in 2025. IWSR’s latest data show Irish whiskey volumes and value both increased by 2% across the major markets it tracks, even though the US — by far the category’s largest market — fell 3%. At the same time, Bord Bia says the value of Irish whiskey exports from Ireland fell 5% in 2025 to about €930 million, with US exports also down 5%. Stocks had been built ahead of American tariffs and the weaker dollar made trading conditions more difficult.
Those figures are measuring different things, so they are not contradictory: global consumer-market performance can improve modestly while the value of product exported from Ireland during a particular year falls.
It does mean Slane cannot simply blame its problems on the disappearance of consumer interest in Irish whiskey.
As of September 2026, Brown-Forman continues to list Slane among its active portfolio brands.
The Slane website also continues to take bookings for public distillery experiences. The standard two-hour tour is advertised at €40, while its €60 “Slane Amplified” experience includes a more detailed tasting. The tasting range currently includes the core Triple Casked blend, Extra Sherry Wood and a distillery-exclusive Batch Strength release.
Interestingly, the website still describes Slane as a “working distillery” where visitors can witness whiskey making in action. Given Brown-Forman’s explicit confirmation that production has stopped, that wording appears not to have been updated rather than evidence that distilling has restarted. There has been no public announcement of a production restart that I can find through 21 September.
There are also small signs that brand-development work continues.
Slane Castle Irish Whiskey Limited filed the trademark CUISLE CHOPAIR for alcoholic beverages and distilled spirits in 2025. The UK Intellectual Property Office recorded the application, while another Slane application — “BORN ON THE BANKS OF THE RIVER BOYNE, IRELAND” — appeared in its 2026 trademark journal in Class 33.
A trademark filing does not mean a new whiskey will necessarily be released but it is at least evidence that commercial and brand-development activity has continued around Slane despite the production pause.
Slane’s story now has an unfortunately ironic symmetry. Slane was originally built because there wasn’t enough whiskey. Today there is plenty of whiskey; what it needs is more people buying it.
