What percentage of light does brown glass block?

• A. 98%
• B. 75%
• C. 50%
• D. 20%

Answer: (A)

Brown glass is specifically designed to block a significant percentage of light, particularly ultraviolet (UV) light, which can degrade the quality of beer and other beverages over time. The correct percentage of light that brown glass typically blocks is around 98%. This high level of protection helps to preserve the flavor, aroma, and overall integrity of the contents inside the bottle, making it a popular choice for many breweries. While other types of glass, like clear or green, allow more light to pass through, brown glass effectively reduces light exposure, which is crucial for maintaining the quality of light-sensitive beverages. As a result, this makes brown glass an excellent packaging option for products that need to be shielded from light damage.
