The abundant traces of the Pinus halepensis resin also known as Aleppo Pine indicate presence of conservation as well as the Greek retsina wine. This type of resin was used to give a unique flavor to white wine but such pine species did not grow in the Bulgarian region and it must have been imported from Greece mainland or the Aegean islands (e.g.
Thasos, Rhodes) where the retsina was usually produced. Over the past several decades, there have been growing a big interest in the chemical analyses of the organic residues from the material that had been stored in the vessels.
In the course of the Classical and Hellenistic period, Ancient Thrace was considered to be the periphery of the Greek, or more precisely Mediterranean world, however, discovering rich tombs and royal centers suggest that the Thracian society represented a high-quality standard. With the purpose to achieve the highest prestige, the Thracian social elite was inspired by the Greek traditions, including typical symposia.
Evidences of transport amphorae, transporting i.a. wine, in Thrace indicate close commercial contact with the Greek area.
