It celebrated the beginning of spring, particularly the maturing of the wine stored at the previous vintage, whose "pithoi" were now ceremoniously opened. During the feast, social order was interrupted or inverted, the slaves being allowed to participate, uniting the household in ancient fashion. The Anthesteria also had aspects of a festival of the dead: either the Keres () or the Carians () were entertained, freely roaming the city until they were expelled after the festival. A Greek proverb, employed of those who pestered for continued favors, ran "Out of doors, Keres! It is no longer Anthesteria".
