Beer has been around for quite a while, some of the first to brew it were the ancient Egyptians thousands of years ago. However, bottled beer only started to be a thing in the 19th century.
While people around the world likely recognize a beer bottle when they see one, many may not realize why beer bottles look the way they do. Beer bottles don’t come in a variety of colors for a distinct reason, most of it comes down to practical science with a few marketing concepts thrown in.
• The Clear Glass Bottle
Glass was initially used to grip beer because it was found to be the best material for keeping the liquid fresher for longer periods of time. But it took some time to come to the conclusion that clear glass was not the way to go when it came to beer. Clear bottles of beer left in the sun quickly turned sour. This was because the clear glass allowed UV rays to penetrate the beer and alter the flavour. This started to become a problem as gallons of beer were getting wasted and the makers were in a disarray.
• The Inception of Brown Bottles
In the 1930s, people discovered a darker bottle colour which would block out the rays and keep the beer fresh for a longer period of time. This is because brown glass bottles can reduce the impact of light on beer. The bottles helped the beer makers all across the world. The demand kept on rising and the beer kept on flowing.
• The Green Era
Post World War 2, brown glass was high in demand, and some breweries had to resort to using clear glass bottles which were cheaper. To make beer bottles look royal and of premium quality, the brewers came up with green colour to attract beer lovers again. This became a status symbol for several European brewers, which is why it is still common to see beers in the green glass bottles, despite the fact that they don’t work as well as brown bottles to protect our brew.
Many times over we can still see the six pack holders will have cardboard shielding along all sides of the bottles for added protection because of this reason.
Some brands still stick to clear bottles ?
Many major brands still use clear bottles. Newer hop products, such as Tetrahop extract, are chemically manipulated so as not to break down as easily in the presence of UV light. That is how some beers get away with being packaged in clear glass, which offers no protection from sunlight.
If you would like that luscious brew to stay fresh, just store it in a dark, cool environment without major temperature swings. Yes, that’s your refrigerator.
