Brewery Ommegang (Cooperstown, NY)
What you'll do: Before you head to the actual brewery, take a tour of another Cooperstown destination: Howe Caverns. Once a year, Ommegang lowers cases of its Hennepin, Three Philosophers, or Abbey Dubbel into the 52° cave, where they age for 9mos -- the brewers claim they’re the first to cave-age beer in America in over a century. The aging location moves each year, but you'll spy it while underground. Next, head to Ommegang, where the tour gets points for actually being different: they brew their Belgians using open fermentation and other means.
What you'll drink: Snag a $3 tasting-pass for a sampler glass you can fill with six beers of your choice, but buy a bottle or five of the cave-aged brews to take home -- it’s hard to track them down outside the brewery’s store, and the aging gives the ale an amazing, complex flavor.
