Implication

Experimental study reveals accurate classification of charred wild and domesticated grape seeds, indicating a reliable tool for tracing ancient viticulture.

Key Points

Develop an automated morphometric method using computer vision and discriminant analysis to accurately distinguish wild from domesticated charred grape seeds in archaeological records.
Carbonised modern wild (Vitis vinifera subsp. sylvestris) and cultivated (V. vinifera subsp. vinifera) grape seeds across seven temperatures (180–340°C for 120 min) using a hearth and muffle furnace.
Extracted size and shape metrics with computer vision and modeled classifications using stepwise linear discriminant analysis (LDA).
Applied the classification model to archaeological charred grape seeds from Early Bronze Age Sardinia (2017–1751 2σ cal. BC).
Achieved an overall correct classification rate of 93.3% when discriminating modern charred wild seeds from cultivated grape seeds.
Identified 75.0% of the archaeological Early Bronze Age grape seeds from Sardinia as wild grape (subsp. sylvestris).
