Did you know beer bottles are usually brown or green for a reason? It’s not just about looks or marketing. These colors help protect the beer from sunlight, keeping its taste and freshness intact.
Reports says beer has been stored in glass bottles since the 19th century because glass helps keep it fresh. However, brewers soon noticed that clear glass wasn’t ideal. Sunlight could ruin the beer’s flavor and give it a bad smell.
Reports say brown bottles are best at blocking UV rays, which helps prevent chemical reactions that can ruin the beer’s taste. By keeping out light, they protect the beer’s delicate flavors. Breweries started using brown bottles to solve this problem, and even today, they are the most popular choice for beer packaging.
During World War II, brown glass became scarce, so breweries switched to green bottles. Over time, people started linking green bottles with high-quality beer. However, green bottles don’t protect beer from UV rays as well as brown ones, making it more likely to develop a bad taste. Still, many breweries stick with green bottles for tradition and branding.
Clear bottles let people see the beer inside but don’t block UV rays, leaving the beer exposed to light damage. To fix this, some manufacturers now add UV-protective coatings to clear bottles. This helps protect the beer while keeping it visible.
In today's times, cans are popular because they fully block sunlight, keeping beer fresh. They also chill quickly and are easy to carry for outdoor activities.
