Empty whiskey bottle (Fallout: New Vegas)

The empty whiskey bottle, also known as "empty whisky bottle," is a miscellaneous item

Gameplay
An empty whiskey bottle is simply what the name suggests, a bottle of whiskey which has been drunk or otherwise emptied.

Fallout: New Vegas provides a use for empty whiskey bottles, in the form of giving them to Rose of Sharon Cassidy when she is a follower as an ingredient in moonshine. If the Honest Hearts add-on is installed, empty whiskey bottles are an ingredient used in crafting wasteland tequila. Also, the Old World Blues add-on allows the player character to take these to the Sink to be refilled, turning them into purified water.

Locations
Numerous empty whiskey bottles can be found throughout the Mojave Wasteland, appearing in virtually all major areas of both games, either placed in the environment or located inside containers. Additionally, vendors may sell the item, though none are specifically guaranteed to have any in stock.
