Experts have drawn attention to the potential risk of wine kept in clear glass bottles could develop an undesirable stench due to a process called “light strike”. Light strike often occurs when UV rays react with the components of wine. Wine experts Susie Barry and Peter Richards advocate for the use of opaque glass in order to preserve the wines’ integrity. While red wine provides integral protection due to its higher polyphenol content and dark-colored bottles. Wines such as rosé, white, and sparkling wine are more vulnerable to light strike. To reduce this risk, experts recommend consumers to store these types of wines out of direct sunlight.
However, Mark Driver, proprietor of the Rathfinny Estate, warns consumers against purchasing wines in glass entirely, especially delicate wines. He goes on to question the industry’s custom of using clear glass for wines, even going so far as to compare wine to beer bottling customs. He points out that beer is usually bottled in an amber-colored glass in order to prevent photochemical deterioration. This comparison emphasizes the need for an industry reform in order to be able to guarantee wine quality.
So, next time you’re purchasing wine or storing your wine selections, keep in mind the insights provided by professionals regarding how light affects wine quality. By keeping these things in mind, you can preserve your favorite wines, ensuring an enjoyable experience every time.
