Since 1820, Alexander Keith's Brewery has been making some of the best craft beer in North America. The historic beer manufacturer opens to the public for tours and special events during the off-season between June and October so you can see the care the company puts into its beer-making process. Each tour lasts an hour and features guides decked out in 19th-century costumes. At the end of the tour, anyone older than 19 can sample one of the craft brews in the Stag's Head Tavern.
