Miruvor

Miruvor is a clear liquid made by the elves, which renews the strength of the drinker. It is warm and fragrant, and used at festivals. Elrond gave Gandalf some mirovor before the Fellowship left Rivendell. Gandalf then passed this on to the members of the Fellowship as needed (First on Caradhras, Next when they stopped to rest, and lastly before the gates of Moria). By the time the Fellowship entered Moria, the drink was gone.
