Olifir was a spicy alcoholic Todanian beverage.
In 2376, after being stranded in the Delta Quadrant by an Iconian gateway, Sinimar Arkathi opened one of the last bottles of olifir to calm his nerves.
Olifir was forbidden to be drunken by the V'enah, the slaves of the Todanians. (VOY novel: No Man's Land)
