Brewers started to use glass because it kept beer fresher, longer. However, there was one serious issue, if the beer was left in the sun too long, brewers found the beer would smell and taste skunky. Literally, it smelled just how a skunk smells. Scientists discovered that Ultra Violet rays from the sun break down the alpha acids in hops which then react with the sulfur present in beer to form a chemical that is almost identical to the chemical that skunks use to spray predators. Those damn UV rays. The solution was to tint the beer bottle to protect it from UV rays. Similar to how sunglasses help protect your eyesight; the dark brown beer bottle helps protect the beer from going bad. Why the green beer bottle then? Green beer bottles offer very little protection from the sunlight. Though, slightly more than a clear bottle, it does not help protect from UV as much as one might want. However, the story behind green bottles is kind of awesome.
