Why Beer Is Mostly Sold in Brown and Green Bottles

Beer is a drink that many adults enjoy, and it usually comes in bottles.

Have you ever noticed that most beer bottles are brown or green?

There is a clever reason for that.

Beer can get spoiled by sunlight.

When light touches beer, it reacts with something from hops, the plant used to make beer.

This reaction creates a bad smell that people call 'skunky.'

Brown bottles are the best because they block most of the light that hurts beer.

Green bottles became popular after a big war, when brown glass was hard to find.

Clear bottles give almost no protection, so brewers add special ingredients.

The best protection of all comes from metal cans, which keep light and air out completely.
