Why is beer in green bottles?

First of all, beer is filled in green (or other dark) bottles, mainly because beer is afraid of light, especially draft beer (fresh beer that has not been pasteurized) has a lot of yeast, and light will cause the yeast to grow quickly, and at that time, you will find that the beer has white hairs.

Dark bottles are filled, mainly to avoid light affecting quality.

Cooked beer (usually pasteurized) is not the same because of the different production processes, the degree of filtration before product filling is different, resulting in different amounts of yeast in the product, poor filtration, relatively large number of yeasts, temperature increases, bottle cap seal leakage, and light.

It will affect the rapid growth of a small number of yeasts surviving in the wine, coupled with the long sales cycle, which will affect the quality of the wine.

The color of the bottle is just to make sure that light is avoided as much as possible.

For ***, beer with a short sales cycle, even if it is filled in transparent bottles, in a short time, it will not affect the quality of the wine.

Therefore, what bottle to use is not based on the manufacturer's preference or material cost.

Rather, it is determined by a series of specific conditions such as winemaking process, sales cycle, storage environment, sales radius, etc.

Also, one of the important ingredients in beer is hops, which give beer its special bitterness.

Whereas, the ingredients in hops are light-sensitive and will decompose under the action of ultraviolet rays in sunlight, producing unpleasantness"The sun stinks".Colored glass bottles can reduce the occurrence of this reaction to some extent. However, the brown bottle works better than the green one.

There are beers in colorless and transparent bottles on the market, and the hops added to the production are processed.

Why are beer bottles all green?

Here's why:

Although beer has a long history, it has not been bottled for a long time, around the middle of the 19th century.

Originally, it was thought that glass had only one color, only green, and not only beer bottles, but also ink bottles, paste bottles, and even glass on doors and windows had a little green. In fact, this is due to the fact that the glass-making process is not perfect.

Later, with the improvement of glass technology, it was possible to produce bottles of other colors, but it was found that green beer bottles could delay the deterioration of beer. Around the end of the 19th century, this green bottle was specially produced to fill beer, and it slowly passed down!

The "Blue Monument" in the Louvre Museum in Paris records the Sumerian people of Babylon in the 3rd century BC who sacrificed beer to the goddess. In fact, the inventors of beer were none other than the Sumerians.

Before 6,000 B.C., the Sumerians who lived in Mesopotamia made their original beer from barley malt, although the beer did not have rich foam.

Around 3000 B.C., the Semitic people of Persia learned how to make beer, and they also carved the method of making beer on a tablet and dedicated it to the goddess of farming. In 2225 BC, beer became popular among the ancient Babylonians, who used it to entertain their guests. At that time, the ancient Egyptians and ancient Babylonians noticed the medicinal value of beer and used it to make medicines.

The Greeks were also very fond of drinking beer, and they learned how to brew beer from the Egyptians.

In the 4th century AD, beer spread throughout Northern Europe. The variety of beers began to become richer, among which the mead made by the British from a mixture of honey and water was one of the more famous. A dark beer that appeared in England was also very famous, and it was already very similar to the modern dark beer.

In the 1st century AD, the Irish brewed their own beer similar to the modern pale beer.

Beer is served in green or brown bottles, why is that? Why are beer bottles green?

In the Northeast, beer has a nickname, that is, "big green stick", as the name suggests, it is a green bottle, but why are most beer bottles green? Is it to relieve eye strain? Or is it to forgive people who drink and brag to each other?

However, for a long time after World War II, the supply of brown bottles in Europe was in short supply, and some famous beer brands reverted to green bottles for beer. Soon after, many brewers began to use green bottles.

Later, although the glass manufacturing process was advanced and could remove these impurities, the cost was too high to consider, andIt was discovered that green bottles can delay the taste of beerTherefore, at the end of the 19th century, people specially produced green glass bottles for beer, and the tradition of green beer bottles was preserved.

With the popularization of refrigerated appliances and the advancement of sealing technology, some businesses even make their packaging more distinctiveAdd ferrous oxide (FeO) and chromium oxide (CRO3) to the glass as dyes to make beer bottles look greener. Beer bottles** are designed for sustainable development and energy conservation, and solar energy is recognized as one of the cleanest sources of energy. The protection of the environment requires the joint efforts of the people of the whole country, and I believe that the effect is obvious to all, and this issue is urgent in the current situation, and the joint participation of the people of all ethnic groups in the country is the greatest affirmation, and the strong support of international organizations is also indispensable, and it is the responsibility of all mankind to care for the earth.

Why are beer bottles green?

The preservation of beer requires that most of the beer bottles are green, which is more beautiful and conducive to preservation.

This prevents the special chemical reaction of the alcohol when the sun hits it.

Maybe the beer is yellow or green, which is a good way to block out the outside light.

Because there is a substance in the glass material that requires a high process to remove, the green color is revealed.

That's to prevent sunlight from hitting the bottle and causing a chemical reaction in the alcohol.

Because the green bottle is convenient and easy to make, it will use the green bottle.

Because green glass bottles are the easiest to manufacture, most of them are green.

This is because when the original glass manufacturing process was not very exquisite, it was difficult to remove impurity ions such as ferrous ions from the raw materials, so the glass produced was green.

The reason why beer bottles are mostly green is because it provides the best protection. Beer bottles need to protect the beer inside from spoilage due to light, especially UV rays. Green glass absorbs most of the UV rays, reducing the exposure time of the beer.

In contrast, a clear beer bottle can only absorb very little UV light, while a brown beer bottle can only absorb a portion of it.

In addition to protecting performance dust pins, green beer bottles have the advantage of hiding sediment in the beer. The proteins and yeast in beer can settle in the bottle, which can affect the appearance and taste of the beer. Green glass can reduce the visibility of these sediments and make the beer more aesthetically pleasing.

In addition, green beer bottles can also make the brand more recognizable. Many beer brands use green bottles to distinguish themselves from others. For example, the Heikine beer bottle is green, making it more recognizable and memorable in the market.

Although green beer bottles have many advantages, they also have some disadvantages. For example, green beer bottles are more expensive to manufacture because more raw materials and energy are required to make green glass. In addition, green glass is more difficult to ** and reuse than transparent glass, as it needs to go through more processing and screening.

In conclusion, the reason why green beer bottles have become mainstream in the beer industry is that they provide the best protection properties, can hide sediment in beer, and can make the brand more recognizable. However, they also have some drawbacks that need to be taken into account when making and handling molds.

1. Process limitations: In the middle of the 19th century, the level of science and technology was not high, and the manufacturing process was immature, and the impurities such as ferrous ions in the raw materials could not be removed, and the glass made was more or less green. 2. Storage needs:

Putting the beer in a green glass bottle can reduce direct sunlight, delay the taste of the beer, and store it for a longer time.

The name "beer" is a homonym from a foreign language, and the word "beer" for beer did not exist in Chinese dictionaries in the past. Later, some people called beer "bier" according to foreign names such as Germany and the Netherlands; In the UK, it is called "beer"; In France, it is called "biere"; In Italy, it is called "birre"; Romanian called "berea" and so on, these foreign languages all contain the sound of the word "beer", so the translation into the Chinese word "beer" created this foreign language text, and because it has a certain amount of alcohol, the word "beer" is used in the translation, and it has been sold in the same way to this day. Because beer is made mainly from barley malt, the Japanese also call beer "ale".

Beer is a type of beverage brewed with malted barley as the main raw material. It has the lowest alcohol content and high nutritional value, and the ingredients include water, carbohydrates, protein, carbon dioxide, vitamins, calcium, phosphorus and other substances. It is known as "liquid bread".

There are several reasons why beer bottles are green:

1. Process limitations: In the middle of the 19th century, the level of science and technology was not high, and the manufacturing process was immature, and the impurities such as ferrous ions in the raw materials could not be removed.

2. Storage needs: Put the beer in a green glass bottle with a branch to reduce direct sunlight, delay the taste of beer, and store it for a longer time.

At that time, not only beer bottles, but also ink bottles, paste bottles, and even window panes had a slight green tinge. Dr. Cao Chengrong of the Institute of Physics of the Chinese Academy of Sciences told reporters: "This is because the original glass manufacturing process is not very exquisite, and it is difficult to remove impurity ions such as ferrous ions in the raw materials, so the glass produced is green."

Later, the glass manufacturing process was advanced, which could remove these impurities, but the cost was too high, and people found that green wine bottles could delay the taste of beer, and putting beer in green glass bottles could reduce direct sunlight, delay beer taste, and store it for a longer time. Therefore, at the end of the 19th century, people specially produced green glass bottles for beer, and the tradition of green beer bottles was preserved.

Beer is served in green or brown bottles, why is that? Why are beer bottles green?

On the other hand, the use of green beer bottles is mainly to make people feel a relaxed and harmonious atmosphere, but also to shade the light well, reduce photosynthesis, so as to maintain the quality of beer, beer is particularly sensitive to sunlight. People will find that the impurities contained in the ferrous ions in the beer will react with the sunlight and make the beer taste worse, so people want to put the beer into a dark green or coffee-colored bottle, which can effectively block the sunlight, and the beer is packed into a green or coffee bottle, in addition to the beauty, in fact, there is also a lot of helplessness, although it is not difficult to solve the problem of ferrous ions today, but the use of beer bottles of this color has become a tradition.

Beer has a very long history, but it wasn't very long to put beer in glass bottles, around the mid-19th century. At that time, there were no special beer bottles, and wine bottles were more likely to be used. At this time, there may be more green bottles, and you should know that the color of the glass in that year depends on the manufacturing process a lot, and it is not just the color you want.

So, by the end of the 19th century, when there were special beer bottles, the tradition of green bottles was preserved.

Until the 1930s. It has been found that if you put beer in a brown bottle, you can make it taste better when it has been left out for a while. The reason is that it was discovered later that light can promote the reaction of alpha acid and sulfide in beer, making the taste very bad, and using brown bottles can prevent this reaction from happening, and the taste is better.

As a result, there is an increase in the use of brown bottles of beer.

After World War II, there was a time when there were not enough brown bottles in Europe, so some of Europe's better brands of beer reverted to green bottles. Because these beers are indeed of good quality, green bottle beer has become synonymous with high-quality wine tasting for a while, so more manufacturers have followed suit and used green bottles. At this time, with the popularization of refrigerators and the advancement of sealing technology, the necessity of using brown bottles has basically disappeared, and it will not bring better quality than other color bottles.

However, an old brand of beer will not easily change the packaging significantly, at most in the glass processing technology to make the color more pure and bright or whatever, a mature brand packaging color of a large change should be rare, so, brown and green are still the mainstream of beer packaging.
