In this study we propose to adapt wood traceability technique using chloroplast DNA markers to this industrial context. The retrieval of DNA and haplotype determination has been tested on different types of wood samples that can be collected in cooperage firms and a clear effect of wood treatment on DNA degradation has been observed. Despite the poor quantity and quality of DNA retrieved from staves haplotypes could be determined on a large proportion of the samples permitting to check the genetic conformity of woods with announced provenances. In several cases our study proved the existence of unlabeled oak woods originating from eastern Europe and the incorrect use of the names of famous French forests. chloroplast DNA diversity haplotype Quercus traceability Résumé - Contrôle de l origine géographique des bois de chêne utilises en tonnellerie. L importation croissante de bois de chêne et le manque de garantie sur son origine liés à l expansion récente de la tonnellerie íranẹaise rendent nécessaire la mise au point d une technique fiable permettant de contrôler l origine des bois de chêne.
