Besides its well-developed herding, the Vučedol Culture planted crops. Most frequent were emmer wheat, Einkorn wheat, and barley. The earth was worked with plows made of deer or cattle horns, and grain was ground with a handstone against a millstone. Representations of millstones and the work with them are known from Ancient Egyptian drawings and models. In Vučedol houses that had three rooms, one always served as a storeroom, recognizable by shallow pits in the floor in which large vessels were buried for keeping grain or perishable foods. In the late phase of the culture we find round baked-clay plates up to 4 cm thick; these served for baking flatbread. Also often found are solid low vessels fixed to the hearth, in the fire, with their bottoms upward so that large cooking pots could be placed on them. Such objects are not known in any culture before or since Vučedol.
Barley was also used for brewing beer, as finds of large vessels testify. Their use for beer-drinking is confirmed by contemporaneous Sumerian reliefs in Mesopotamia, which show two human figures drinking beer through long straws. The straws were probably made from reeds, and were used to drink from the middle of the vessel, since dregs settled on the bottom, while chaff floated on the surface.
