Comparative Degradation Study of Free-Run Rosé Wine Under Accelerated and Typical Storage Conditions and the Influence of Antique Green and Flint Glass Bottles

This research focuses on the key degradation parameters of rosé wines under different storage conditions and the protection provided by Antique Green and flint glass. The evolution of the chromatic characteristics, the polyphenolic profile and riboflavin content were compared for wines under accelerated and typical storage conditions.Rosé wines in flint and AG bottles were analysed after 15 months of exposition to natural/fluorescent light and after 16, 32 & 64 hours of intensive irradiation and regulated temperature, including control samples in darkness conditions.The study concluded that storage conditions and coloured bottles led to different tendencies in terms of Colour Intensity, but always evolving to more yellow and less red wines. The accelerated tests set-up demonstrated validity to predict the evolution of crucial chemical compounds. The results suggest the potential of this accelerated tests methodology to estimate preservation times and anticipate the advancement of key chemical parameters and longevity markers.
