In the earliest times there were basically three ways to pack wares for transport: baskets, sacks, and amphorae. Wheat and other grains were usually transported in sacks but stored in earthenware pots. Amphorae were mostly used for liquids, wine and olive oil above all. Large jars and craters were used for drinking water. Pretty much everything else, including perishable fresh food were carried and kept in baskets.
