Do beers bottled in clear bottles contain formaldehyde order to protect it from sun damage?

Here's why:

* Formaldehyde is a toxic chemical that is not used in beer production. It's harmful to humans and would render the beer undrinkable.

* Sunlight degrades the flavor and aroma of beer due to a chemical reaction called photo-oxidation. This reaction is primarily caused by UV light, not visible light.

* Brown bottles filter out UV light, which is why they are commonly used for beer. This helps protect the beer from degrading.

* Clear bottles allow UV light to penetrate, leading to faster spoilage. This is why clear bottles are often used for beers that are intended to be consumed quickly, like light lagers.

In summary, formaldehyde is not used in beer production. Brown bottles are used to protect beer from sun damage, while clear bottles are used for beers with shorter shelf lives.
