Why are Beer Bottles Brown

Beer has come a long way since the days of casks and leather flagons. In fact, the decision about what to store beer in has plagued people for centuries. Before refrigeration and pasteurization, beer storage was a significant issue. Beer had to be consumed quickly to prevent spoilage.

The Evolution of Beer Bottles

The idea of storing beer in bottles was developed by a monk several centuries ago. He had placed beer into a wine bottle to take on a picnic and left it in the bottle for quite some time. When he found the bottle later, the beer was still fresh. This marked the beginning of bottled beer.

Sealing the beer bottle was the next major challenge. Beer makers experimented with various methods, including wax and cork. The cork solution lasted for hundreds of years until the wire loop closure was developed many years later. For a long time, beer bottles were short, bell-shaped, and sealed with wire, similar to mason jars.

Most beer makers embossed the name of their beer directly onto the bottle. This was before the days of paper labels, and embossing was the only way to let people know what kind of beer they were drinking. Embossing remained common well into this century, before the advent of paper labels.

Over time, the shape of beer bottles evolved, becoming thinner and taller, resembling the beer bottles we are familiar with today. Beer bottles remained brown or green until the present day. This was primarily because refrigeration had not yet been invented. Without a way to keep beer at a consistent temperature, it was crucial to protect it from direct light to preserve its freshness.

After refrigeration was invented, it became less important to keep the bottles opaque. However, many beer makers continued to use dark bottles out of tradition. Only recently have some companies started to break away from tradition by using clear beer bottles. Most of these clear bottles are used for imported beers like Corona, as well as wine coolers and blended beverages such as Zima.

Another theory about why beer bottles are brown relates to the glass-making process itself. Although this theory has never been proven, many people suggest that it was historically much harder to make clear glass than colored glass. Apparently, crystal-clear glass required techniques that were not developed until the industrial age.

Regardless of which explanation you believe, the tradition of brown beer bottles is deeply ingrained. People are accustomed to seeing beer in brown bottles, and new beers marketed in bottles of any color other than green or brown often struggle to succeed.

It is a well-known fact that modern American beers taste fresher and more flavorful when stored in brown bottles. Many American beers still lose their texture and flavor when exposed to direct sunlight. One advantage of using brown bottles universally is that it makes recycling the glass easier.
