When it comes to wine bottles, green is a color that is commonly associated with certain types of wines. While there are various reasons why wine bottles are green, it primarily has to do with preserving the quality and longevity of the wine inside.
One type of wine that is typically kept in dark green bottles is red Bordeaux. The deep, rich color of Bordeaux wines is best preserved in dark bottles that shield the wine from exposure to light. This is because prolonged exposure to light, especially ultraviolet light, can cause the wine to undergo a process known as “lightstrike” or “light damage.” This can result in off-flavors and aromas, ultimately compromising the wine's quality. So, the dark green bottles act as a protective shield, keeping the wine in optimal condition.
On the other hand, dry white Bordeaux wines are often stored in lighter green bottles. The reason behind this is that white wines generally do not require as much protection from light as red wines. While they can still be affected by lightstrike, it is to a lesser extent. Therefore, lighter green bottles are used for white Bordeaux wines to offer some protection while still allowing the wine's true color to be appreciated.
Moving beyond Bordeaux, there are several other wine regions that also prefer green bottles for certain types of wines. Burgundy wines, both red and white, are often housed in green bottles. The same goes for wines from the Rhone Valley, including both reds and whites. Additionally, wines from regions like Mosel and Alsace in Germany, along with many Champagnes, are also commonly found in green bottles.
The choice of green bottles for these wines is not just a matter of tradition or aesthetics. It is primarily driven by the need to protect the delicate flavors, aromas, and characteristics of these wines from the harmful effects of light. Green glass has the ability to filter out a significant amount of ultraviolet light, thus minimizing the risk of lightstrike.
As a sommelier and brewer, I have personally witnessed the importance of using green bottles for preserving the quality of wines. In my experience, wines that have been stored in green bottles tend to exhibit fresher, more vibrant flavors compared to those stored in clear or light-colored bottles. The green glass truly acts as a shield, allowing the wine to age gracefully and develop complex flavors over time.
Green bottles are commonly used for certain types of wines, including red Bordeaux, dry white Bordeaux, Burgundy wines, Rhone wines, Mosels, Alsaces, and many Champagnes. The choice of green glass is primarily driven by the need to protect these wines from the detrimental effects of light, particularly ultraviolet light. By using green bottles, winemakers can ensure that their wines maintain their quality, flavors, and aromas, allowing wine enthusiasts like myself to enjoy them to the fullest.
