Lager: Stella Artois Brewery, Leuven, Belgium

In 1926, the Artois brewery in Leuven, Belgium (which has been in existence since 1366), produced a beer so bright it was given the name Stella, Latin for "star."

Which goes to show sometimes a company requires a few centuries to discover its true calling. Today, Stella Artois is sold in more than 80 countries.

The hourlong tour at the Stella Artois brewery divulges all the beer's secrets (so they say). Visitors sample a cool Stella in the cozy Den Thuis bar before being guided to the Stella Artois shop, where they can stock up on chalices. And maybe a bottle opener.

Cost: €8.50 (U.S. $11.30).

Stout: Guinness Storehouse, Dublin

Guinness is like a beer milkshake and the tour of the brand's headquarters is just as filling.

It starts in the atrium next to the world's largest pint glass, which rises up through the middle of the seven-story building.

As the thorough and at times interactive tour moves up each floor, visitors learn about the beer's state-of-the-art brewing process, its "cooperage" (barrel-making) and how it's transported to more than 150 countries.

Awaiting at the top is a pint of Guinness (certificate included) in the Gravity Bar, which affords visitors a 360-degree view of Dublin. There's a reason the Guinness Storehouse is the No. 1 attraction in Ireland.

Cost: €16.50 (U.S. $22).

Whisky: Glenfiddich Distillery, Dufftown, Scotland

Glenfiddich is the world's most awarded single-malt Scotch whisky, having claimed more big-time international medals since 2000 than any other single-malt Scotch.

In the heart of the Scottish Highlands, its distillery is nearly as decorated. The free classic tour runs through 19th-century warehouses and mash rooms and includes three drams of Glenfiddich.

For a more in-depth look (and more chest-hair-producing whisky samples), visitors can opt for the explorers tour or even the pioneers tour, where they can taste a 30-year-old whisky and procure a rare, cask-strength bottle of Glenfiddich.

Cost: Free to £75 (U.S. $121).

Tequila: Casa Herradura, Amatitán, Mexico

If premium tequila is your drink, Guadalajara, Mexico, and a locomotive known as the Tequila Express is your trip. In this case, the Tequila Express is a literal train.

Thirty kilometers later, visitors arrive at Casa Herradura, home of the award-winning and picturesque Herradura Tequila distillery. Surrounded by mountains and agave fields, the tour takes in the original factory and a few 100 percent agave tequilas (silver, reposado, añejo).
