Why are beer bottles mostly green and cannot be made transparent?

Beer bottles are green for a certain reason, which contains some principles of food fermentation. We all know that beer, like ordinary wine, is fermented from some grains such as wheat. The wine in our country is basically fermented by grain. But why are beer bottles green and other bottles transparent? We can all see that in fact, many white wine bottles are transparent, but beer bottles are green, brown and blue, but we rarely see beer bottles are transparent.

In fact, there are some reasons and reasons, including some knowledge about food. That is to say, the fermentation mode of beer we see is different from the white wine we usually drink. We all know that liquor brewing needs koji, but there is actually a problem. Actually, beer fermentation is used, and some bacteria are used. That is to say, if the bottle preserved later is changed to white, all the light will shine on the wine, and the wine will produce some bad smells, that is, some photosynthetic bacteria will play a role in the brewing process. Photosynthetic bacteria, if using sunlight, will produce some bad smells, making beer undrinkable and affecting the quality of beer.

In this case, the loss of the manufacturer is also great, and the green beer bottle will absorb a lot of sunlight, so that the sunlight will not directly hit the beer, ensuring the quality of the beer. So there is a reason to use green bottles, so it is difficult for us to see beer in transparent bottles at ordinary times.

The packaging of each food has been carefully considered, which is also a problem that some food developers and R&D food engineers have to consider. These are all issues that people need to consider, so they will never put beer in green bottles. Beer brewing has been going on for many years. After so many years of development, using green bottles is the best choice.
