Antioxidant capacity and phenolic composition of different woods used in cooperage

► The botanical species influences the antioxidant capacity of oenological woods. ► Antioxidant capacity was very closely correlated with the polyphenolic content. ► Quercus robur and Castanea sativa were the species with the highest antioxidant capacity. ► Prunus avium was the specie with the lowest antioxidant capacity. ► Phenolic acids and ellagitannins are mainly responsible for the antioxidant capacity.
