A very important role in the diet of ancient Vinča-culture communities was played by einkorn and emmer wheat, which are extremely rarely cultivated today. In the archaeological layers, the two species of wheat were usually found together. This has led to the conclusion that they were sown one along another, as a measure of precaution in case one of them had a poor yield. Cereals were kept in large containers called pithoi. With the help of smaller vessels that could be held in one hand, the portions needed for daily meals were taken out from pithoi. Cereals were ground using small quern-stones, where a special tool, a handstone, was used to crush the grains.
