Although beer has a long history, it hasn't been put in bottles for long, starting from the middle of19th century.

At first, people thought that glass had only one color, only green. Not only beer bottles, ink bottles, paste bottles, but even the glass on doors and windows is a little green. In fact, this is caused by the imperfect glass making process.

Later, with the improvement of glass technology, although bottles of other colors can also be produced, people found that green beer bottles can delay the deterioration of beer. /kloc-this green beer bottle was specially produced at the end of 0/9 and passed down slowly!

On the "Blue Monument" of the Louvre Museum in Paris, in the 3rd century BC, the Sumerians in Babylon sacrificed beer to the goddess. In fact, the inventor of beer was Sumerians.

Before 6000 BC, Sumerians living in Mesopotamia brewed original beer with barley malt, but the beer foam at that time was not rich.

Around 3000 BC, the Sumerians in Persia learned how to brew beer, and they also carved the method of brewing beer on wooden boards and dedicated it to the goddess of farming. In 2225 BC, the ancient Babylonians became popular with beer, and they entertained their guests with beer. At that time, ancient Egyptians and ancient Babylonians noticed the medicinal value of beer and used it to make medicine. Greeks also like drinking beer very much. They learned how to brew beer from the Egyptians.

In the 4th century AD, beer spread all over northern Europe. The varieties of beer began to become rich, among which mead brewed by British people with honey and water is a famous one. A kind of dark beer in England is also very famous, which is very similar to modern dark beer. In the 1 th century, the Irish brewed a beer similar to modern light beer.
