Notes: Fallout 3

 * Drinking only beer and selling other drinks (whiskey, scotch, wine, vodka, and moonshine) allows players to make the most of their items because the other drinks are worth more than beer.
 * It may be a good idea to drink beer to increase your carry weight, then fast travel to a safe location with a marketplace in order to easily get to a place to sell the extra goods without being overencumbered.
 * Beer is the most commonly found consumable in the Capital Wasteland, with 536 bottles placed throughout. This number does not include vendor items, items found in containers, or those from add-ons.
