The most expensive bottle of liquor in the world is a bottle of tequila in a solid platinum and white gold bottle from the Tequila Ley .925 company. The liquor in this bottle was made out of 100 per cent blue Agave liquid and was aged for six years. This platinum tequila bottle was purchased by a private collector on 20th July 2006 for $225,000.
Here is a picture of the platinum tequila bottle as seen in Mexico City, Mexico, a few months after it was sold. With the sale of this bottle, the Tequila Ley .925 company broke the Guinness World Record for the most expensive bottle of liquor ever sold.
For those people who can't afford the $225,000 platinum tequila bottle, the company also sells Gold and Platinum tequila bottles for $150,000 and Silver and Gold tequila bottles for $25,000.
