Oak from France but also from America and Eastern Europe is the major wood used for cooperage, because of its organoleptic properties. For instance, it is generally recognized that among the two predominant French oak species, Quercus robur L. (pedonculate oak) contains more tannins but fewer volatile compounds than Quercus petraea Liebl. (sessile oak). However, so far, all of the attempts to establish correlations between wood chemical properties and the origin, the species or even the position in the tree have relied on the targeted analysis of selected compounds. Here, we report the first FTICR-MS analysis of extracts of oak woods, which were initially selected from three French forests, traditionally supplying either pedunculate or sessile oak wood for cooperage. The aim of this study was to characterize these extracts in order to reveal metabolites or family of metabolites that could discriminate both the species and the geographical origins.
