$620K for a bottle of booze. Worth it?

Sotheby’s has sold what they say is the world’s most expensive bottle of whisky to a private collector in Hong Kong for $628,000.

Can a bottle of booze be worth that much, or is the cheap stuff just as good?

"In terms of how much it costs, it's got to be on how much was made in the first place," says Patrick Hobbs from Boisdale Whisky Bar.  "If it was a long time ago, did they have the raw ingredients to make it?"

Becky took a seat at the bar to find out what makes a whisky worth the price tag.
