Is there a kind of wine called iced red wine?

Icewine (English ice wine, German Eiswein) is ice wine as its name implies. Like the word "organic", ice wine has different definitions in different countries. Generally speaking, ice wine refers to the sweet white wine brewed by frozen grapes when picking. But in Canada and Germany, where authentic ice wine is produced, the definition of ice wine emphasizes natural freezing. The definition of iced wine in China Wine Brewing Technical Specification is: grapes are delayed to be harvested, when the temperature is below -7℃, the grapes are kept on the branches for a certain period of time, and then they are harvested and squeezed to make wine with this grape juice.

Ice wine was first born in 1794 in Franken, Germany. At that time, it was found that the sugar and flavor of grapes were concentrated after freezing and thawing until the first frost. After more than 200 years of development, ice wine has become the best in wine. Only Germany, Austria and Canada can produce real ice wine. Niagara, Ontario, Canada is the most famous ice wine producing area in the world.

VQA (Canadian Vintners Quality Alliance) defines iced wine as wine that is naturally frozen from grapes at a temperature below 8℃. Grapes are squeezed when they are frozen into solid state, and a small amount of concentrated grape juice flows out. This grape juice is slowly fermented and bottled after a few months. In the process of pressing, the outside temperature must be kept below-8℃.

In Germany, Eiswein belongs to Qualit? Tswein grade, and subject to relevant laws and regulations. In Canada, the production and brewing of iced wine is controlled by VQA (Wine Merchants Quality Alliance). Real Canadian ice wine must comply with VQA regulations to ensure product quality. One of the most important regulations is that ice wine must be produced by natural methods, and artificial freezing is never allowed. This makes it extremely difficult to brew ice wine-grapes must be properly protected to avoid drastic temperature changes; Moreover, because the grapes for making ice wine are the last grapes left on the vine, people should try to prevent birds and animals from stealing grapes.

Appropriate harvest time is very important for ice wine. The ideal picking temperature should be-10℃ to-13℃, because grapes can get the best sugar content and flavor at this temperature.

When the grapes are harvested, they must be carefully picked by hand. At this time, the grape yield is extremely low, and often a whole grape tree can only produce one bottle of ice wine, which is why ice wine is so expensive, usually selling half a bottle, but it is really worth the money.
