BrainStuff Season 4 Episode 8 Why Are Wine Bottles Usually Green?

Have you ever wondered why most wine bottles are green? In season 4 episode 8 of BrainStuff, host Christian Sager delves into the science and history behind this common practice in the wine industry.

Sager starts by explaining the importance of protecting wine from light, which can cause the wine to spoil and lose its flavor. The most damaging type of light is ultraviolet (UV) light, which can penetrate glass and affect the wine molecules. This is where the green glass comes in. Green glass is able to block out most UV light, protecting the wine from harm.

But why green? Sager looks back to the origins of wine bottles, which were usually made of clay or earthenware during the ancient times. It wasn't until the Roman Empire that glass blowing techniques were developed, allowing wine to be stored in glass bottles. At the time, glass was expensive and difficult to produce, so wine bottles were usually clear or brown.

However, during the 17th century, the French monarchy realized the importance of preserving wine and the green glass bottle was born. King Louis XIV declared that all Champagne bottles must be made of green glass, because it was deemed the best color for blocking out harmful UV rays. This practice soon spread throughout the industry and became the norm for most types of wine.

Sager also explains that green glass has become synonymous with quality in the wine industry. Although many wine bottles are now made of different colors, green remains the preferred option for many winemakers. This is partly due to tradition and also because of the perceived quality associated with green glass.

The episode also explores other factors that can affect the quality of wine, such as temperature, humidity, and air quality. Sager explains that storing wine properly is crucial for maintaining its flavor and aroma. He also touches on the role of wine cellars and the importance of choosing the right type of cork for the bottle.

Overall, season 4 episode 8 of BrainStuff provides an interesting insight into the history and science behind one of the most common practices in the wine industry. Whether you're a wine enthusiast or simply curious about the origins of everyday products, this episode is a must-watch.
