In the cold winter, the weather becomes more and more cruel, walking in the street by the cold shivering people everywhere, even if everyone's warm measures are done well, but still can't avoid the cold winter "frozen" hands "frozen" feet. At this time, some people may have a question: the weather is so cold, will the liquor solidify and freeze?
01 Wine degree through the course
The wine-making technology in China has always been different from that in the West. The vast majority of Chinese wine is made from raw crops, while western wine is made from grapes and other fruits. Around 5000-3000 BC, grain brewing appeared in China. At that time, rice wine was produced, which was estimated to be only a few degrees 39bet-xsmb-xổ số tây ninh-xổ số binh phước-xổ số binh dương-xổ số đồng nai. Later, in the Song Dynasty, people gradually mastered the method of making wine with Jiuqu and began to make wine in large quantities. The degree of wine was further improved, reaching more than ten degrees.
In the Northern Song Dynasty, after Liao and Jin entered China, distilled wine was created. After the Yuan Dynasty established a great Eurasian territory and completely ruled the Middle Earth, distilled spirits were placed above all other alcoholic drinks, in order to highlight their own Mongolian culture. Although the Ming dynasty and the rise of the fermented, makes Chinese traditional winemaking process carry on, but later pronounced ching, for high concentration and extremely cold distilled spirits, so the entrance spicy, warm distilled spirit gradually replaced the mellow rich, is very sufficient power extraction, became the mainstream, until now.
02 How is alcohol strength tested?
Alcohol is defined as the percentage of pure ethanol (alcohol) contained in a wine. If THE CONTENT OF PURE ETHANOL IN 100 MILLILITERS OF SOME WINE is 10 millILiters, THE wine degree of this KIND OF wine is 10 degrees, but the capacity is to increase or decrease with the temperature. Chinese regulation is to test the temperature of 20℃. That is, 20℃, 100 milliliters of pure ethanol content in the wine, is the wine degree.
How many degrees of liquor
The current standard liquor is generally 28 degrees, 33 degrees, 35 degrees, 38 degrees, 39 degrees, 40 degrees, 43 degrees, 45 degrees, 48 degrees, 50 degrees, 52 degrees, 53 degrees, 56 degrees, 60 degrees, 68 degrees.
The freezing point of ethanol is lower than that of water, so it is not easy to freeze in winter. The freezing point of pure ethanol is -117°C, and the freezing point of ethanol aqueous solution varies according to the ethanol content. The freezing point of 40-degree liquor should be about -25°C.
Alcohol freezes at -117°C, and liquor freezes at different degrees. Generally, the icing point of high liquor is about -80°C, and the lower the degree, the easier it is to freeze. Generally, liquor with a temperature above 46 degrees Celsius will not freeze even in cold areas.
In terms of maotai-flavor liquor, daqu maotai-flavor liquor alcohol content basically all is 53 degrees, so maotai-flavor liquor in China is basically not frozen, but contains high unsaturated fatty acid, this substance soluble in alcohol, only under the environment of rapid temperature change, the unsaturated fatty acid will be released, and the composition such as ethyl palmitate, ethyl oleate at low temperature would precipitate, It causes the body to become cloudy, so it is normal to have this sometimes in very cold conditions.
And drink wine in addition to keep out the cold warm, winter and relaxing tendons, appetizers xiaoshi, promote sleep, the effect such as cardiovascular disease, it is no wonder that the winter has been a liquor sales busy season, but also need to remind here a bit, that is in the winter to drink, with hot water temperature better, so as not to because the cold wine and stimulation to the body!
