Green is the most common color in wine bottles because green bottles are effective in preventing oxidation of wine in the presence of light, whether artificial or natural. A small amount of oxygen is good for wine, which helps the wine to bloom. However, if the wine is in contact with oxygen, it will make the wine quickly rough and eventually become a vinegar-like liquid.
However, different regions and types of wines still differ in the choice of bottle color, not the dark green, light green, colorless, amber, etc. are common bottle colors:
Bordeaux red wine - dark green
Bordeaux dry white wine - light green
Bordeaux Sweet White Wine - Colorless Burgundy and Rhone Valley - Dark Green
Mosel, Germany and Alsace, France - medium to dark green, some wineries will use traditional amber
Rhineland - Amber, some wineries also use green bottles
Champagne - usually medium to dark green; pink champagne will use a colorless or green bottle
In general, for wines that need to be aged for a long time (such as Bordeaux and Burgundy red wine), the bottles tend to use darker colors, while for ready-to-drink wines (mostly fresh taste) White wine), the bottle can be light green or even transparent and colorless.
