Ah, fermentation. And distilling.

Where would the world be without them? Yes, the Irish might have taken over the world had God not invented whisky, but what about rum, gin, vodka, beer and wine?
We'll likely never know the answer to that question, but we can find out exactly how the drinks that rule the world are made. Whichever flavor you like to toss back, somewhere there's a booze tour with your name on it. From Belgium to Barbados, here are 10 of our favorites.

Bourbon: Woodford Reserve Distillery, Kentucky

Kentucky's oldest and smallest distillery, Woodford Reserve lovingly crafts its bourbon in small batches. Maybe that's why it's the official bourbon of the Kentucky Derby.

At the distillery, also a National Historic Landmark, visitors take a guided tour that explains the history of bourbon, the bottling process and how Woodford Reserve does something special with all five sources of bourbon flavor.

For example, they don't just use water, they use deep limestone well water. Big difference (as they'll explain). Best of all, guests get to linger with the award-winning craft bourbon.
On the Corn to Cork tour you can dive deeper into the bourbon-making process. Or you can just start serving up mint juleps.

Cost: $7.
