When you think of the place where whisky is born, a factory floor may not spring to mind, but the truth is that industrial-sized distilleries make most of the whisky in the world—and it’s almost always extremely high quality. Size—or, really, scale—does matter when it comes to turning out enough great whisky to satisfy millions of thirsty drinkers, and the measures that these mega-producers take to ensure a delicious final outcome are impressive at every turn.

In most of the world, distillery capacity is measured in liters of pure alcohol (lpa) or liters of absolute alcohol (laa), though U.S. distillers favor proof gallons as the unit. Capacity measures how much whisky a distillery can make, not necessarily how much it is making—though it’s safe to say that producers at this scale are making a whole lot. Check out the world’s largest whisky distilleries below, and keep reading for recommendations on the best industrial-scale whiskies to try.
