Boom, Bust & Early Branding: Scotch Whisky in the 20th Century

By the end of the 19th century, Scotch whisky looked unstoppable.

Production had expanded, blends were booming, railways had opened markets and whisky had become one of Britain’s great industrial success stories. And then, almost overnight, it unravelled.

As whisky writer Dave Broom and historian Iain Russell discuss in this third in-depth conversation, the collapse that followed wasn’t caused by a single villain but by whisky becoming, in Iain’s words, “a victim of its own success.”

Iain Russell & Dave Broom in conversation for the history module of the Diploma in Single Malt Whisky.

The Pattison Crash: When Speculation Ran Ahead of Reality

The infamous Pattison Crash of 1898 is often mentioned in whisky histories, but rarely unpacked properly. (Read an in-depth piece from Iain here.)

“The success of the big blends led to people laying down stocks for future demand,” Iain explains. “Demand was growing, and like today, people thought: we want a piece of this action.”

Whisky became a speculative asset. Investors bought spirit not to bottle or drink, but to sell on later. Blenders borrowed against whisky that didn’t yet exist. Distilleries were built on optimism rather than demand.

“As everyone knows,” Iain notes, “in business you have to speculate to accumulate but over-speculation leads to disaster.”

When confidence cracked, panic followed. Warehouses were overfilled. Investors rushed to sell. And when Pattison’s opaque financing practices were exposed, the collapse triggered bankruptcies, prosecutions and a prolonged industry depression.

“The effects,” Iain says, “lasted at least the next fifty years.”

Overstocked Warehouses and the Birth of the Age Statement

Ironically, one of modern whisky’s most powerful ideas emerged from this wreckage.

“There was so much whisky lying about in warehouses that had to be cleared,” Iain explains, “that companies began to put age statements on bottles.”

Age statements already existed but now they became standardised and commercialised.

“Johnnie Walker Black becomes a 12-year-old in 1909. Chivas Regal becomes a 25-year-old around the same time.”

At first, this was simply pragmatic: they had the whisky, so they used it. But it also had consequences.

“You educate the consumer that older is better,” Dave Broom added, which became an idea that would shape whisky marketing for the next century.

Fewer Distilleries, Bigger Players

The crash also reshaped the industry’s structure.

By the 1890s, blenders were building distilleries to secure supply. Grain distillers were consolidating. Malt distillers were struggling to survive independently.

“What you see,” Iain explains, “is a circling of the wagons.”

This leads eventually to the great amalgamations of the 1920s: Johnnie Walker, Dewar’s, Buchanan and to malt distillers, grain distillers and blenders becoming part of the same system, not rivals.

War, Tax, Prohibition: Survival by Adaptation

If the Pattison Crash weakened Scotch, the first half of the 20th century nearly finished it. High taxation, ideological temperance, the First World War, Prohibition, the Great Depression... all arrived in quick succession.

“At one point in 1933,” Dave notes, “there were only two distilleries operating in Scotland." Iain adds: "Glen Grant and Glenlivet.”

Yet Scotch survives. Partly by luck, partly by adaptability. Prohibition, counter-intuitively, helps some brands.

“Bottled Scotch was seen as a safe drink,” Iain explains. “A lot of Prohibition booze was dangerous. Scotch gained kudos.”

Distribution networks built during Prohibition - via Canada, the Caribbean and American partners - become invaluable after Repeal.

“Scotch ends up being the last man standing,” Dave says. “Bloodied, but still there.”

Defining Whisky: Law, Trust & Control

Out of chaos came control.

The early 20th century finally forces the industry to answer a fundamental question: what is Scotch whisky?

Malt distillers feared dilution. Grain distillers feared exclusion. The issue went to a Royal Commission in 1908.

The resulting definition - astonishingly broad by today’s standards - legally unified the industry for the first time.

“It signals the end of the great division,” Iain explains. “From this point, the industry consolidates.”

Minimum ageing laws followed. Regulation increased. Trust mattered again.

Branding Scotland: Tartan & Heather

Alongside the legal definition came a growing sense of cultural identity.

Early branding leaned heavily into Victorian ideas of Scotland: tartan, Highland warriors, ruined castles, soldiers, dogs.

“It was shorthand,” Dave says. “Boom: that's Scotch.”

Later, whisky adapted again, moving through music hall culture, Harry Lauder, Tommy Dewar’s showmanship and eventually into modern advertising.

By the mid-20th century, Scotch reinvented itself for America.

“It becomes aspirational,” Dave explains. “A symbol of sophistication.”

From post-war rationing to the Rat Pack era, Scotch kept aligning itself with the cultural moment because, as Dave puts it:

“If Scotch doesn’t move with the times, it dies.”

Foundations for the Modern Industry

By the 1950s and 60s, American investment, export focus and rebuilding Britain’s economy brought distilling back to life.

New distilleries were built. Old ones reopened. And the foundations of today’s Scotch whisky industry were laid... all shaped by crisis, compromise and creativity.

This article draws from just one of four extended video discussions between Dave Broom and Iain Russell, now in the History module of the Diploma in Single Malt Whisky (online and in-person). In the Diploma, these conversations sit alongside structured learning, historical context and guided analysis, allowing you to explore not just what happened, but why it still matters to Scotch whisky today. If you want to understand how Scotch survived collapse, war, prohibition, and cultural change - and how those pressures still echo in the modern industry - the Diploma provides the full picture.
