Oktoberfest (Munich, Germany)

Oktoberfest claims the top spot for its unrivaled scale: 6 million visitors consume 7 million liters across 14 tents over 16 days, a tradition since 1810 that sets the global standard for beer festivals. Attendance alone is 50% higher than #4 Belgian Beer Weekend's visitor count, while the volume of beer poured dwarfs the typical festival by over 10x. The 4,000 beers sampled at #2 Great American Beer Festival may offer variety, but no single event matches Oktoberfest's sheer throughput of 437,500 liters per day.
