Why don't other countries have vinegar?

Before answering this question, let's know what vinegar is. Acetic acid, mixed with water, sour agent, seasoning, spice and food coloring.

How was vinegar invented? Why is it called "vinegar"? Legend has it that in ancient China, that is, Yuncheng, a man named Du Kang invented wine. His son Heita also learned wine-making technology from Du Kang. Later, Heita led the tribe to Zhenjiang, Jiangsu. There, they felt it was a pity to throw away the distiller's grains after brewing, so they stored them and soaked them in jars. On 2 1, as soon as I opened the jar, a smell that I had never smelled before came to my nose. Under the temptation of rich fragrance, Heita tasted it, and it was sweet and sour, full of fragrance, so it was stored as "sauce". What is the name of this sauce? Heita named this sour water "vinegar" and added the word "one" to the number 2 1. ?

Because vinegar can be produced by itself in the natural environment, ancient humans began to eat vinegar from a very early time in the world. Generally speaking, eastern countries brew vinegar with grains, while western countries brew vinegar with fruits and wine. In China, it is generally believed that vinegar was brewed in the Western Zhou Dynasty, but some people think that vinegar originated in Shang Dynasty or earlier. Acyl was called vinegar in Han Dynasty. In the west, vinegar appeared in ancient Egypt. Because they are all fermented and brewed, it can be considered that wine and vinegar are homologous to some extent, and all ancient civilizations that can make wine generally have the ability to make vinegar.

Due to the differences in raw materials, technology and eating habits, the taste of vinegar varies greatly from place to place. Baoning vinegar has a long history, which began in the first year of Changxing in the Five Dynasties Tang Dynasty (AD 956). Baoning vinegar is produced in the ancient city of Langzhong, Sichuan. It has the characteristics of soft sour taste and mellow sweet taste. With the popularity of Sichuan cuisine, it is sold all over the world. There is a saying that "without Baoning vinegar, Sichuan food will have no customers". In northern China, the most famous vinegar is Shanxi mature vinegar invented in Ming Dynasty. Shanxi people are famous for being jealous all over the country, and there is a joke called "Give up your gun and don't pay vinegar". Henan specialty vinegar is the most famous in the Central Plains.
