A 4,000-Year Story of the Institutions That Kept Craft Alive

This is the third and final article in The Wood Series - three linked pieces exploring the deeper story of the cask in whisky. Part One, The Jerez Secret, examined the complex truth behind sherry cask maturation and what “sherry cask” really means on a label. Part Two, Beyond Oak, explored the science of alternative wood maturation - mizunara, chestnut, acacia, and the revolutionary STR process developed by Dr Jim Swan.

This final piece returns to the beginning: to the institutions, guilds, and regulatory bodies that have shaped, protected, and transmitted the cooper’s craft across centuries and continents. All three articles were inspired by The Cooper’s Art, which first made the argument that the barrel maker may matter more to what is in your glass than the distiller. If you have not read that piece, I would encourage you to start there.

There is a building in Devonshire Square in the City of London that I find myself returning to in my mind more often than its modest Georgian exterior might suggest is warranted. It is Coopers’ Hall - the home of the Worshipful Company of Coopers, one of the oldest livery companies in the City, ranked 36th in the order of precedence among the 113 that still meet, deliberate, and carry the weight of centuries of London guild tradition.

Those who know me well will understand why this building matters to me. I am a member of the Athenaeum on Pall Mall, where I chair the Whisky Interest Group. I hold a position at the National Liberal Club on Whitehall. I am a Cadet in the London Squadron of the Musketeers of Armagnac - an order, as I discussed in our article on collecting, that carries its own deep French institutional heritage.

I am, in other words, someone who believes that institutions matter: that the organisations human beings build to carry knowledge, maintain standards, and transmit craft across generations are not merely bureaucratic structures but living repositories of something essential.

The guilds of the coopering world are exactly that. And their story is, in miniature, the story of how whisky came to be.

The Worshipful Company of Coopers: London’s Hidden Custodians

The Coopers’ Company of London is first mentioned in the records of the Mayor’s Court on the 22nd of May, 1298 - making it one of the oldest organised trades in English history. ¹ It received its Royal Charter of Incorporation from Henry VII on the 29th of April, 1501, which stipulated for “one Master and two Keepers (or Wardens) of the Commonalty of Freemen of the Mistery of Coopers.” ²

Henry VIII added a grant of arms in 1509. The original motto - Gaude Maria Virgo, Rejoice, Virgin Mary - was changed to Love as Brethren after the Reformation, a shift that tells its own story about the Company’s survival through centuries of religious and political upheaval. The arms feature three Tudor lilies, the hoops of a barrel rendered as annulets, and the tools of the cooper’s trade - the broad axe and the croze - rendered in azure on a golden chevron. It is a coat of arms that encodes the craft itself.

At the height of its commercial power, in the 15th, 16th, and 17th centuries, the Company regulated the coopering trade through Acts of Parliament. It controlled the gauging of all casks used for the storage of ale, beer, and soap. Its Sealer - bearing a branding iron - visited cooperages throughout the City to inspect and certify the work. It extended its authority two miles beyond the City walls, prosecuting “aliens” - anyone from outside London - who infringed upon its members’ rights. ³

With the expansion of seaborne trade under Henry VIII, casks were required for everything that left English shores: food, drink, ammunition, and cargo. Coopers prospered accordingly.

The Company’s first hall was established in Basinghall Street in 1522. That hall was destroyed in the Great Fire of London in 1666, rebuilt on the same site, rebuilt again in 1865, and destroyed by fire in the Blitz on the night of 29 December 1940. The Company’s present home at 13 Devonshire Square is the fourth - an outwardly Georgian building that is, in fact, a surviving merchant’s house from the late 17th century, furnished with the artefacts of six centuries of the trade it represents. ⁴

Today, the Worshipful Company of Coopers is no longer a trade regulator. Like most of the City liveries, its commercial functions were gradually displaced by industrialisation, changing labour conditions, and the growth of more specialised regulatory bodies. But it has not become irrelevant.

It remains an active charitable foundation, supporting two educational institutions: the Coopers’ Company and Coborn School of Upminster, founded in 1536 - making it one of the oldest continuously operating schools in England - and Strode’s College in Egham, Surrey. ⁵

It provides the Worshipful Company of Coopers Certificate in coopering, one of the few formal credentials available to those entering the craft in England. And it keeps the memory and meaning of the trade alive in a city that has largely moved on from the physical work of making things by hand.

In June 2022, the Company inaugurated a Cask Rolling Race at Guildhall Yard - a public celebration of the craft that has drawn attention and visitors. In July 2023, they established an annual event to honour the feast of St Abdon, the coopers’ patron saint. ⁶

The Company’s mascot - Ajax, a Shire horse owned by a Liveryman, who carries two English oak pin casks decorated with the Company badge - visits events, distilleries, and heritage sites in an act of gentle, charming advocacy for a craft that the wider world has barely noticed is at risk.

Jerez: The Consejo Regulador and a Different Kind of Guild

Three thousand miles south-west of Devonshire Square, on the Atlantic coast of Andalusia, sits Jerez de la Frontera - and with it, one of the most important regulatory institutions in the story of whisky, even though whisky is never mentioned in its founding documents.

The Consejo Regulador del Vino de Jerez was founded in 1935, two years after Spain’s Estatuto del Vino of 1933 first codified the concept of geographic protection. ⁷ It is the oldest wine regulatory body in Spain - older than the appellation system governing Rioja, older than Cava, older than any other Spanish wine region with a protected designation. Its function is to write, enforce, and promote the rules that govern what may legally be called sherry: which grapes, which zone, which methods, which minimum ageing periods.

As I described in The Jerez Secret - Part One of this series - the Consejo’s relationship to whisky is oblique but profound. The industrial production of sherry-seasoned casks for Scottish distilleries operates within the Consejo’s framework: the 2015 Sherry Cask certification programme, which guarantees that seasoning wine comes from within the Denomination of Origin and that the duration of seasoning meets minimum standards, was the Consejo’s response to growing concern about the authenticity of sherry cask labelling in the whisky world. ⁸

The broader story of the Consejo connects to the history of the coopering trade in Jerez itself. The oldest references to cooperage in Jerez date back before the discovery of the Americas - a reminder that the barrel-making tradition of southern Spain is as old as the trade it serves, and considerably older than whisky.

The toneleros of Jerez - the Spanish coopers - developed their own guild structures, their own standards, their own certification systems for the butt, the puncheon, and the hogshead. The cooperages that now supply Scotland - Tevasa, Vasyma, Páez Lobato, Tonelería del Sur - are the contemporary descendants of a craft tradition that has been continuously practised in this city for at least five hundred years. ⁹

The irony, as The Macallan’s extraordinary vertical integration into the Jerez cooperage and bodega supply chain makes clear, is that Scotland now depends on these Spanish institutions more than most whisky drinkers realise. When Edrington acquired a 50% stake in the Tevasa cooperage and its associated sawmills in 2024, it was not simply a corporate transaction.

It was the latest chapter in a relationship between British whisky production and Andalusian craft that has been running, in various forms, since the transport casks first began arriving on Scottish docks in the eighteenth century. ¹⁰

Kentucky: How a Jobs Bill Changed the Flavour of Whisky

The institutional story of coopering in America is quite different from the guild model of Europe, and its most important chapter was written not in a cooperage but in the United States Congress.

The requirement that bourbon be aged in new, charred oak containers - the regulation that ensures every bourbon barrel is used only once for bourbon production and then passed on to the Scotch, Irish, and other whisky industries - was not the product of ancient tradition or artisanal wisdom. It was the product of lobbying.

The first written requirement for new charred oak barrels in American whiskey law appeared in 1938, inserted into federal regulations by Representative Wilbur Mills of Arkansas. ¹¹ The provision was - at least in part - driven by political pressure from the coopers’ unions and the timber industry, both of which stood to benefit enormously from a legal mandate ensuring permanent demand for new barrels.

If every batch of bourbon required a brand-new charred oak container, and if bourbon was - as it increasingly was - produced in the tens of millions of gallons annually, the coopering and lumber industries had a guaranteed market of extraordinary scale.

The rule was codified into the character of American whisky by the Federal Alcohol Administration Act of 1935 and its subsequent amendments, and gained its fullest expression on the 4th of May, 1964, when the United States Congress passed Senate Concurrent Resolution 19 - declaring bourbon “a distinctive product of the United States” and granting it the same protected status that Scotch enjoyed in Scotland. ¹²

Bourbon could be made only in America. It would always be aged in new charred oak. And those containers could not be reused for bourbon production.

The downstream consequences of this decision for the global whisky industry are almost impossible to overstate. The US bourbon industry currently has more than 16 million barrels of bourbon aging - a number that exceeds the population of Kentucky by a remarkable margin. ¹³

When those barrels are emptied, the majority travel north to Scotland, east to Ireland, south to the Caribbean, and across the world, where they provide the raw material for the maturation of spirits that would otherwise have access to nothing like the volume of quality cask they require. The first-fill bourbon barrel is the world’s most important spirits recycling system, and it exists because of a congressional jobs bill.

There is something I find genuinely moving about this. The specific vanilla and caramel character of a bourbon-cask Glenfiddich, or a bourbon-finish Laphroaig, or a hundred other whiskies that define the category - these flavours are shaped in part by a political negotiation that happened in Washington DC in the 1930s and by the lobbying of a union that no longer exists in its original form. The institutions that shape what we drink are not always the ones we imagine.

Japan: One Cooperage, All Orders Outstanding

The Japanese coopering story sits in a different institutional register entirely from the guild tradition of London or the regulatory framework of Jerez, and it is worth spending some time with it because it reveals something important about the fragility of craft knowledge when the institutions that transmit it are very small.

As I described in Part Two of this series, Japan’s relationship with mizunara - the native oak that imparts sandalwood, incense, and kara spice to the spirit matured within it - began as a wartime necessity. The country’s coopers learned to work with a wood that is genuinely difficult: twisted, moisture-heavy, prone to leaking, requiring up to three years of drying time before it can be made into a barrel, and sourced from trees that take two hundred years to grow. ¹⁴

The entire global supply of professionally made mizunara casks for the spirits industry flows from a single independent cooperage: Ariake Sangyo, founded in 1963 by Toshio Odawara in the Fushimi district of Kyoto, originally as a supplier of wooden crates for sake bottles. In 1984, recognising the growing demand from shochu and whisky producers, Ariake expanded into making full-size casks - becoming Japan’s only independent cooperage, a status it still holds. ¹⁵

When Gary McLoughlin of Ireland’s Glendalough Distillery described his experience of acquiring mizunara casks - “To acquire a mizunara cask, you must blind bid against the giants of Japanese whiskey on one day per year to get your year’s supply” - he was describing a system in which Suntory, Nikka, Chichibu, and their rivals compete at auction with furniture makers and cooperages for raw timber that is genuinely scarce and becoming scarcer. ¹⁶

Ariake Sangyo’s factory chief, in conversation with Japanese whisky journalist Mamoru Tsuchiya, noted that orders for mizunara casks were arriving from around the world faster than production could match: “We are getting orders for Mizunara casks from all around the world, and our production can’t keep up.” ¹⁷

Now led by the fourth generation of the Odawara family, Ariake Sangyo is a striking example of a craft institution built on accumulated family knowledge rather than formal guild structures. The skills of working with mizunara - selecting the right stave despite the wood’s twisted grain, managing the three-year drying process, assembling and repeatedly checking a barrel that may leak and require disassembly and reassembly multiple times before it holds water - are not codified in any curriculum or tradesman’s examination. ¹⁸

They are held in the hands, eyes, and judgement of people who have spent their working lives with this particular, peculiar wood.

What happens to that knowledge if the demand for mizunara casks - currently growing faster than Ariake can meet it - eventually creates pressure for production methods that sacrifice precision for volume? What happens when the third and fourth generation of a family cooperage are no longer followed by a fifth?

These are questions with no comfortable answers, and they are the coopering equivalent of the question raised in our earlier article about Scotland’s 300 skilled coopers serving an entire national industry.

The institutions that carry craft do not sustain themselves automatically. They require attention, investment, and - above all - the explicit recognition that what they carry cannot simply be reconstructed from a manual or a training video once it is lost.

The Thread Running Through It All

Reading these institutional stories together - London, Jerez, Kentucky, Kyoto - a common thread emerges that I think matters for how we understand whisky.

Each of these institutions, in its own way, represents an answer to the same fundamental problem: how do you preserve and transmit knowledge across generations when the knowledge is embodied, tacit, and takes years to acquire?

The answer, in each case, is some form of organised community - a guild, a regulatory body, a cooperage run by a family through four successive generations - that creates the social structure within which knowledge can be transferred from person to person, in the way that all genuine craft knowledge must ultimately be transferred: by demonstration, repetition, mentorship, and practice.

The Worshipful Company of Coopers does this through its apprenticeship certification and its network of Liverymen who maintain the Company’s archive and collection. The Consejo Regulador of Jerez does it by setting and enforcing standards that protect the integrity of the product and therefore the economic viability of the craftspeople who make it.

The American bourbon regulation does it - improbably, indirectly, as the result of a political lobbying campaign - by creating a perpetual demand for new barrel production that keeps coopering as a living, economically viable trade. And Ariake Sangyo does it in the way that artisanal family businesses have always done it: by passing down the work itself, generation by generation, in a workshop in Miyazaki.

None of these systems is perfect. All of them are under pressure. Scotland’s coopering skills shortage - which I described in The Cooper’s Art as a genuine threat to the quality and diversity of whisky - reflects what happens

A Personal Note to Close

the guilds and the coopers on collaged background

When I pour a well-aged sherried Scotch at a Devon Drams tasting, I am holding the product of the Consejo Regulador’s certification framework, the Worshipful Company of Coopers’ centuries of training standards, the US Congress’s 1938 jobs bill, and the accumulated knowledge of a cooperage family in Miyazaki that has been working with Japanese wood since before most of our attendees were born. All of that institutional history is in the glass.

The flavour is real. The craft is real. And the institutions that preserve it deserve far more gratitude than they typically receive.

At Devon Drams, we will keep raising a glass to all of them.
