Whiskey

 is a food item found in Fallout 3 and Fallout: New Vegas.

Fallout 3
Drinking it increases strength one point, which allows you to temporarily carry 10 extra pounds of items. By drinking this you run the risk of addiction, curable by doctors for a fee. It also boosts your charisma by 1 point while lowering your intelligence by 1 point.

Whiskey has all the same effects as vodka and beer. It is cheaper than vodka and found more often around the Wasteland.

Fallout: New Vegas
It has exactly same design and values as the one in Fallout 3.
