The regional unit Imathia, is a Greek region located in Macedonia, with its largest city being Veroia. Imathia is fortunate to be surrounded by two high mountains: Vermio and Pieria, and by four rivers, the main one being Aliakmon; the longest river originating from Greek soil. As a result, the micro-climate of the area, combined with the well-known kampos (plain), rank Imathia as one of the most fertile areas of Greece. Naoussa is characterized by its wine production, and is one of the most important wine-producing areas, with the most important variety being PDO Xinomauro. Fruit like peaches and cherries, and vegetables like peppers, but also cheese products, sausages, spoon sweets and jams are equally well-known.
