The main reason – to avoid deterioration. Light is an important factor in wine deterioration. Light will decompose and destroy these antioxidants, and they will not be able to protect them. Ultraviolet rays can also react with phenolic compounds, making wine prone to oxidation and deterioration. . In addition, continued exposure to light will produce light pollution from dimethyl disulfide, which can give wine the smell of wet cartons and smelly wool. So, are there any wines in transparent bottles? There are still many wines on the market that are bottled in light-colored/transparent bottles (especially white wine). Generally, this kind of wine is more suitable for drinking when young and does not require long-term aging.
