Beer bottle color influences taste and protection from light

The color of beer bottles can affect taste due to their ability to protect beer from light. Brown bottles block about 98% of harmful UV rays, preventing off-flavors, while green bottles only block around 75%, making beer more susceptible to light damage. Historically, brown bottles became the standard for beer packaging due to their protective qualities. Green bottles emerged during World War II as a substitute, leading to a perception of premium quality, despite their lesser ability to preserve beer. Today, brown bottles are preferred for their superior protection, while green bottles remain popular in certain markets due to branding. Breweries often adapt their practices to manage the challenges posed by green glass, balancing tradition with modern brewing needs.
