The brown glass absorbs the most UV light, which is why it’s used for all types of beer, from ales and lagers to IPAs and pilsners. In addition to blocking out UV light rays, brown glass also has the added advantage of preventing oxidation. You can see this guide to know the difference between ale and beer.

Brown bottled beers have come to be associated with quality, and the simple yet effective design is still popular today. So the next time you reach for that beer in your fridge, take a moment to appreciate its unique hue!
