Wine consumption in Bronze Age Italy: combining organic residue analysis

The early consumption of wine or other grape derivatives (such as vinegar or must) is suggested from organic residues analysis conducted on Bronze Age pottery recovered from two sites in north-eastern Italy, Pilastri di Bondeno (Ferrara) and Canale Anfora (Aquileia, Udine). Pilastri is part of the Terramare culture of the Po plain, from which the archaeobotanical context has suggested that Vitis vinifera L. was known and used during the Middle Bronze Age. At Canale Anfora Vitis, macro-remains were found in earlier levels of the local stratigraphy. Organic residue analysis conducted by gas chromatography coupled to mass spectrometry allowed the identification of tartaric acid in twenty samples out of thirty-one recovered from different ceramic vessels (e.g., drinking cups, coarse ware pots, presumed storage vessels) found at the two archaeological sites and dated to the 15th-14th centuries BC. Based on integrated studies, we suggest that grape juice derivatives (including wine or vinegar) were likely consumed at the sites. This is the earliest direct evidence of grape derivatives consumption in this area. Combined with the botanical evidence, these findings contribute to our understanding of the emergence of wine consumption in the western Mediterranean.
