Sunset Sarsaparilla

Sunset Sarsaparilla is a pre-War company that manufactured the root-beer-type carbonated beverage for which it was named in the United States. According to the cover of All Roads, it has been around since 1918. Some specially marked bottles of Sunset Sarsaparilla have 'special' caps. Sunset Sarsaparilla vending machines can be found throughout the Mojave Wasteland. It can also be found in crates.

Appearances
Sunset Sarsaparilla only appears in Fallout: New Vegas.

Consumable
While playing Hardcore mode, drinking Sunset Sarsaparilla has the negative effect of dehydrating the Courier. Festus will list off some negative side effects, but these don't seem to have an effect on the Courier. Therefore, due to its sheer quantity and low cost, Sunset Sarsaparilla is an excellent consumable that provides a very high health regeneration effect; due to these factors, it supplants the somewhat-scarce Stimpak as a primary healing item in the Mojave.

Note
Unlike Nuka-Cola, drinking Sunset Sarsaparilla generally will not give you rads. The only exception to this rule are the irradiated Sunset Sarsaparilla bottles found in Camp Searchlight.

Behind The Scenes
Sarsaparilla is the root from which root beer took its name. Most modern root beers do not use it anymore, favoring cheaper artificial flavoring instead.
