Despite the importance of wine in the Iron Age Mediterranean, known structures associated with its production are rare. Recent excavations at Phoenician Tell el-Burak have now revealed the first Iron Age wine press in Lebanon. Its remarkable state of preservation enables a systematic study of its plaster to be made as well as a comparison with two other plastered installations at the site. Archaeometric analyses offer new data concerning the composition and technology of Iron Age lime-plaster production, confirming the existence of a local and innovative tradition of plaster production in southern Phoenicia. These results contribute to the wider discussion of Phoenician technology in the broader Iron Age Mediterranean.
