Various forms of alcohol appear in all games of the Fallout series.
Alcoholic beverages have been available throughout the Fallout series in varying forms. In the "classic" set of games—Fallout, Fallout 2, and Fallout Tactics—alcohol served little purpose, providing no obviously beneficial effects, and being useful only under certain limited circumstances. In later games this was changed; alcoholic beverages in Fallout 3, Fallout: New Vegas and Fallout 4 all provide both beneficial and negative effects. Fallout: New Vegas, in particular, places extra emphasis on whiskey through the Whiskey Rose companion perk, essentially turning the item into a combat chem while the perk is active. Unlike most foods, alcoholic beverages appear to be completely radiation-free.
Beer is an addictive alcoholic drink commonly found throughout the wasteland. In Fallout 1, 2, and Tactics, it is only good for lowering the perception of who drinks it, and becoming an addict for it. On Fallout 3 and New Vegas, however, it increases the player's Strength and Charisma by one point while decreasing their Intelligence by one point.
Booze can be found or purchased throughout the Wasteland, most notably in consolidated communities and settlements.
Gamma Gulp beer
Moonshine is an alcoholic beverage which has a more pronounced effect on the user's personality than other types, giving a greater boost to Charisma. Like other alcohol, it raises Strength but lowers Intelligence for the duration of its effects.
Scotch has the benefit of raising a player's Strength and Charisma by one point for a short time, at the cost of lowering Intelligence. The bottles appear to be empty. It should have a glowing orange-brownish color like the whiskey in the game, as Scotch is a type of whiskey, but does not.
Vodka is a distilled alcoholic beverage, made mostly from water and ethanol and then distilled from a fermented substance such as rye, wheat, potatoes or sugar beet molasses. It is also the world's most popular spirit beverage.
Drinking whiskey increases Strength (and before Fallout 4 also Charisma by one point) while lowering your Intelligence by one point. By drinking this you run the risk of addiction, curable by doctors for a fee.
Wine is an alcoholic beverage made from the fermentation of grape juice. It is produced by fermenting crushed grapes using various types of yeast, which consume the sugars found in the grapes and convert them into alcohol.
Absinthe is a green, highly alcoholic beverage derived from wormwood, fennel, aniseed and other herbs and does not stack separately from other alcohols such as beer, vodka, etc.
A novelty drink mixer shaped like a rocket ship, with a black logo on one side with the words "atomic cocktail" surrounding an atom. When consumed, the player is resistant to fire and energy weapon damage.
Rum & Nuka
Rum & Nuka is a variation of Nuka-Cola. This mixed drink, containing some Nuka-Cola combined with rum, has multiple effects, plus one bottle cap is added to the player's inventory when it is consumed.
Sierra Madre martini
The Sierra Madre martini is a potent alcoholic beverage brewed by Dean Domino using toxins from the Cloud and pre-War junk food. It is unusual for a form of alcohol, as it does not have any immediate negative effects.
(Large) Wasteland tequila
Wasteland tequila is an alcoholic drink which can be brewed by the player. Like many other types of alcohol, it boosts Charisma and Strength while lowering Intelligence for the duration of its effects. It also gives added resistance to poison. It has the same appearance as Scotch, with the exception of the label.
Nuka-Cola Dark is an alcoholic beverage which can be found throughout Nuka-World. Boasting a 35% alcohol content it was the Nuka-Cola Corporation’s attempt at entering the alcoholic beverage market. If the player character consumes the beverage the will gain a one point boost to Strength and Endurance at the cost of a one point decrease to Perception and if addicted will suffer from a one point decrease in Agility.
