Do you know the primary reason wine is frequently stored in green bottles? It is to prevent oxidation, which is a common wine fault. Small amounts of oxygen are good for wine, allowing for the flavors to be released, which is why we use decanters. If wine is exposed to too much oxygen, the wine starts to taste more dull.
Wines naturally contain antioxidants to prevent oxidation, but sunlight can quickly reduce the antioxidant count. This is why the tinted green glass bottles are ideal in preserving your wine to maintain it's best quality and taste.
