Nobel Wine, also known as expensive rotten sweet liquor, originated from Hungary, and is a kind of sweet white wine made from white grapes infected with expensive rot after over-ripening. After the mature white grape is infected by Pythium expensive, holes will appear in the peel, and water will evaporate, resulting in higher glucose content. When making wine, some sugar is converted into alcohol by yeast. When the alcohol concentration formed by fermentation exceeds 16%, yeast will die and stop fermentation. The remaining sugar will make the wine have a very rich flavor. The three top noble wine in the world are Tokaji, Tocai,, Rheingau, and Sudai, Bordeaux.

The origin of noble wine

The appearance of noble wine was purely accidental. 1650 Turkish troops invaded Hungary. When the army approached Tocai, it was the grape harvest season. In order to avoid looting by the army, a reformist Christian priest in Tokai called on farmers to postpone picking. People didn't start harvesting until 1 1 was frozen at the beginning of the month. Due to water shrinkage, the grapes have dried up at this time, and the epidermis has become thin and wrinkled, and a layer of mold has appeared. People have no choice but to use it to brew wine. But what I didn't expect was that the wine brewed this year was much more mellow than the wine made from grapes picked in normal seasons. The accidental postponement of picking has unexpectedly brought a new fate to Tocai's expensive rotten wine, and since then it has become brilliant. Tocai noble wine is called "Imperial Wine" because of its incomparable quality in other countries. Even the French upper class will reserve Hungarian Tocai noble wine and call it the king of wine.

The formation of noble wine

After the grapes are fully ripe, a fungus named [Botrytis cinerea] (commonly known as Noble rot) is derived from the fruits, which makes holes appear in the skins of the grapes, and the water in the fruit grains volatilizes proudly because of the holes, which makes the sugar content of the grapes more concentrated. This state is called "expensive rot".

However, expensive rotten grapes can not be easily formed as long as they are picked late. Different from common strains, pythium expensive will not rot the whole grape, but for some special grape varieties, it is hot and dry during the day and wet and cold at night, and an environment with enough moisture can promote the production of pythium expensive. However, too much moisture will not do, which will turn pythium expensive into botrytis cinerea and cause grape necrosis. In rainy days, grapes are also easy to rot and cannot be harvested at all. Pythium expensive erodes the whole bunch of grapes and produces many enzymes in the fruit, among which glycerol, gluconic acid, oxidizing enzymes, laccase and anti-biomass are representative. In addition, tannins and phenolic substances in grape skin will also be integrated into the fruit particles because of the role of Pythium expensive. Although mold will consume sugar, tartaric acid and tartaric acid in grape fruit, it can also evaporate half of the water in grapes and increase the concentration of sugar and malic acid in grapes. So as to brew noble wine with rich flavor.

Noble wine's stunning soft and dense taste, harsh growth environment and the manpower and material resources consumed during harvesting are all the reasons for its high price.
