There’s a divide between Scotland and Ireland as fierce as the Protestant/Catholic split during the Thirty Years’ War or the battles between Sunnis and Shias in the Iran-Iraq War of the 1980s. It’s the debate over who invented whisky.

Both Ireland and Scotland claim to have originated the spirit. Ireland cites its early monastic traditions and the term "uisce beatha" (Gaelic for "water of life") as evidence of whisky production dating back to the 12th century. Scotland, however, argues that its distillation practices, documented in the 1494 Exchequer Rolls mentioning "aqua vitae," predate Ireland’s clear records and point to their refined techniques in the Highlands. Irish advocates emphasize that their missionaries spread distillation knowledge to Scotland, while Scots counter that their innovations in barrel aging and malting set whisky apart as a distinctly Scottish craft. The argument often hinges on differing definitions of what constitutes "whisky," with no definitive proof resolving the dispute, leaving both sides to proudly defend their heritage. Whisky stands out from other alcohols, like beer, due to its intricate production process, which relies on advanced distillation technology to create a high-potency spirit from fermented grains. The use of oak barrels for aging imparts complex flavors, such as vanilla, caramel, and smoky notes, giving whisky its distinctive depth and character.

Today’s guest is Noah Rothbaum, a world-renowned drinks expert and author of The Whiskey Bible: A Complete Guide to the World’s Greatest Spirit. He reveals the history and lore of whisky. We discuss the possibly 5,000-year history of distillation and whisky, how phylloxera wiped out Europe’s vineyards and decimated the market for wine in the early 19th century but kickstarted interest in spirits, how Americans created a separate and distinct spirit, and the future of the drink.
