Two kinds of 75 cL polyethylene terephthalate (PET) bottles (with or without recycled PET) were compared to glass bottles filled with a rose wine, closed with the same screwcaps and stored upright at 20 degrees C in light or in the dark. Analytical monitoring (aphrometric pressure, headspace volume, O-2, N-2, CO2, and SO2) was carried out for 372 days. After the consumption of O-2 trapped during bottling, the total O-2 content in glass bottles remained stable. A substantial decrease of CO2 and SO2 concentration and an increase of O-2 concentration were observed in the PET bottles after 6 months because of the considerable gas permeability of monolayer PET. Light accelerated O-2 consumption during the early months. Finally, the kinetic monitoring of partial pressures in gas and liquid phases in bottles showed contrasting behavior of O-2 and N-2 in comparison with CO2.
