 The classification of staves by their OTR to build barrels allows for different contributions of oxygen to the wine, therefore obtaining wines with different anthocyanin and colour characteristics. This study confirmed that the oxygen entry through oak wood influences the colour of red wine during ageing. Some differences in anthocyanins concentration were observed in wines aged in barrels with different OTR.
