- Posca may also refer to the character on HBO's Rome.
Posca was a type of beverage popular among the Roman legions. It was made from wine that had begun to go sour and turn into vinegar. This was diluted with water and occasionally sweetened with honey. Roman legionaries considered posca to be quite refreshing.
In the New Testament, a Roman soldier is described giving Jesus a sponge soaked in posca to drink (Matthew 27:48).
