500ml glass bottles used in China Baijiu

In daily life in China, most of the Baijiu we buy is marked as 500ml, which is what we call a pound bottle, while the bottle of foreign red wine will be larger, basically 750ml, why is there such a thing on the container difference? Let’s take a closer look below, read the article to find out what you want to know.

First of all, let’s take a look at our Chinese liquor, where we need to use the physics knowledge we learned in junior high school. Density = mass/volume, the mass of the same physical unit volume is a definite value, that is, the density of the same substance is equal. The density of an object has nothing to do with the mass and volume of the object, the density is just a physical property of the object. The specific gravity of water is 1g/ml, and 500ml of water is 500 grams, which is exactly one kilogram. The density of alcohol is smaller than that of water, only 0.8g/ml, that is, 500ml of pure alcohol is only 400 grams, which is eight taels. Therefore, it can be concluded that the higher the alcohol content of the liquor, the lighter the weight. Taking Maotai-flavor liquor as an example, the label of Maotai-flavor liquor is marked with 53% vol, which means that there will be 53 parts of alcohol for every 100% of liquor, and 500ml of liquor contains 265ml of alcohol and 235ml of water. Entering the above formula, it can be concluded that 500ml of sauce-flavor liquor weighs 447 grams. Of course, other trace elements in sauce-style liquor are not calculated, that is, a 500ml glass bottles of sauce-style liquor weighs about nine taels. From this, it can be seen that the 500ml glass bottles of Chinese liquor is influenced by Chinese history.
