How Irish whiskey went from the world's favorite spirit to near extinction and back.

In short: Once the most popular spirit globally, Irish whiskey nearly vanished by the 1970s due to trade wars, prohibition, and stubborn resistance to modern technology. Today, it is the fastest-growing spirit in the world, with a resurgence fueled by new distilleries and a return to traditional, high-quality production methods.

Irish whiskey traces its roots to the 12th century, evolving from medicinal perfumes brought by monks. By the 19th century, it dominated the global market, with Dublin's 'Big Four' distilleries—John Jameson, William Jameson, John Powers, and George Roe—producing massive quantities of 'pure pot still' whiskey. This style, made from a mix of malted and unmalted barley, was a point of immense national pride.

The industry's decline was a perfect storm of internal and external pressures. The 1832 invention of the Coffey still allowed for continuous, efficient production of neutral grain spirit, but Irish distillers famously rejected the technology, viewing the resulting 'silent' spirit as inferior. Meanwhile, Scottish producers embraced the innovation, blending it with cheap imported grain to capture market share. By the early 20th century, a series of disasters—including the Irish War of Independence, US Prohibition, and trade wars with Britain—decimated exports. By 1972, the entire Irish industry had consolidated into just two distilleries under one company.

The modern era began in 1987 with the opening of the Cooley Distillery, breaking the monopoly. Since 1990, the industry has seen explosive growth, with annual sales rising from 4.4 million cases in 2008 to 14 million by 2021. Today, the landscape is vibrant, with 42 distilleries operating across the island as of 2022, reclaiming the global stage through a blend of historical techniques and modern experimentation.
