Founded in 1855, the historic Miller facility preserves Milwaukee's beer legacy. Join the legions lined up for the free, hour-long tours. Though the mass-produced beer may not be your favorite, the factory impresses with its sheer scale: you'll visit the packaging plant where 2000 cans are filled each minute, and the warehouse where a half-million cases await shipment. And then there's the generous tasting session at the tour's end, where you can down three full-size samples. Don't forget your ID.
