This paper approaches the question of the production, trade and consumption of wine in the Northwest of the Iberian Peninsula, particularly in the Portuguese region of Trás-os-Montes, in the south of the conventus Asturum (ancient province of Gallaecia). Despite the total absence of amphorae at the Roman site of Castro de Avelãs (Bragança) and its surrounding area, it is possible that this important product in Roman times, could have been consumed, produced and distributed using a different type of containers. Therefore, we propose the use a specific type of jars for the storage, transport and even production of wine. This hypothesis is reinforced by the gas chromatography / mass spectrometry analysis realized in three vessels, recovered at the archaeological site. The results displayed biomarkers compatible with wine. With these data, we open the discussion about the consumption and production of wine (and other products) in this territory of the Southwest of Gallaecia.
