An ancient liquor, from the pre-War era.
”— In-game description
Booze is a consumable item in Fallout, Fallout 2, Fallout Tactics and Van Buren. The bottle graphic chosen to represent booze appears to be that of Goldschläger liquor.
Booze is a distilled product from high alcohol content made from fermenting corn, grain, potatoes or spore plants. Some booze - the good stuff - may even be left over from before the Great War.
It can be found or purchased throughout the wasteland and most notably, in consolidated communities and settlements.
