The Fire Bottle is a glass bottle containing petrol fuel or a highly alcoholic beverage, with the source of ignition such being a burning cloth stuffed into the neck of the bottle. The cloth serves as a wick and is most effective when the cloth is in contact with the primary incendiary fuel. When used, the cloth is lit and the bottle hurled at a target. When the bottle smashes on impact, the ensuing cloud of petrol droplets and vapor are ignited, causing an immediate fireball followed by a raging fire as the remainder of the fuel is consumed. Modern variations include thickening agents, such as motor oil, to increase burn time and viscosity.
- The Fire Bottle is unlocked in the mission "The Demon Drink".
- Alternatively, the player can also unlock it early by completing the Nosalida Hideout upon arriving in Nuevo Paraiso.

The Fire Bottle is an effective thrown projectile and can be used from cover to assault enemy positions and ignite stagecoaches. The Fire Bottle can also be used to scare away large animals, such as bears, and other animals that are afraid of fire.
The Fire Bottle is less effective than dynamite, unless a player can predict a target's movements and lead his or her throw. When a player is caught in the radius of a thrown fire bottle he stumbles around uncontrollably for a few seconds trying to put out the fire and taking heavy damage. It is also effective for flushing out enemies hiding behind cover.
Altogether, a single Fire Bottle will rarely kill an enemy, and is more of a knock-over weapon. When used the enemy will often just fall over in flames and wriggle around on the ground, which can allow the player to then finish him off with impunity. Other times, the enemy runs around uncontrollably, screaming. If approached by an enemy carrying a fire bottle, a player can shoot the bottle (a shotgun is good for this), causing it to ignite in the enemy's hand. It is also noticeable that the Fire Bottle can become golden like other weapons.
The Fire Bottle can be used in Friendly mode to make people lose control of their character. It doesn't do damage, but still inflicts the uncontrolled running-around-screaming. Beware of other players wielding Fire Bottles, even in Friendly.
- “There are fire bottles over there. Use them to burn down some of these houses.”

- At the time of Red Dead Redemption, gasoline would have been a rare commodity, but strong alcohol would be relatively common. Additionally, there is no historical evidence of the fire bottle existing prior to the Spanish Civil War (1936). It became popularized during the Winter War (1939) in Finland and the USSR as a cheap weapon for the Finns to use against the Soviets. The Finns named it the "Molotov Cocktail" after the Soviet Foreign Minister Vyacheslav Molotov. The in-game weapon would likely use widely available ethyl alcohol, a less-desirable fuel for the fire bottle.
