Are there more green bottle import beers than brown bottle import beers?

>Why is is that beer bottles are sometimes brown, sometimes green, and >sometimes clear, but never blue or red or anything else? Simple. The brown and green are caused by natural impurities (iron?) in the sand used to make the glass. The clear is formed from either purer sand, or glass where they bothered to remove/neutralize the color-adding impurities. Other colors would have to be formed by deliberately adding coloring agents after neutralizing any existing color. Some colors may also be very difficult to form (like blue fireworks). Blue bottles do exist, but are very unusual. -Mike

Glass is made blue by adding a pinch of Cobalt. So, why are beer bottles only clear,green and brown?

In spite of what the Miller Brewing Company would have you believe, beer bottles should not be clear. Beer, wine and whiskey deteriorate when exposed to light (not lite, which is a form beer deterioration created by humans who don't like the taste of beer). Brown bottles do a better job than green ones of keeping light off your beer. Cost of the colors has nothing to do with it. -- Larry Tepper {ihnp4 | allegra}!drutx!druil!lat +1-303-538-1759
