Choes are miniature jugs associated with children. You can see children playing with a small toy cart on this jug.

Once past babyhood, children had their own parts to play in religious festivals.

This chous was probably given to a boy in his third year at the Anthesteria festival. Children would drink the wine poured from the vessel, to prove that they were on their way to being men.

Appropriately, you can also see bunches of grapes on this chous.
