Have you ever drank wine from rotten, frozen grapes? Winemaking technology

Grape winemaking generally chooses fresh and fully preserved grapes. Have you ever heard of rotten and frozen grapes? The editor of small brewing equipment also found it incredible. What kind of small winemaking equipment is used to make wine from rotten and frozen grapes?

The decaying grapes are indeed wine-making and have excellent quality. The climatic conditions suitable for the growth of noble rot fungi are found in the Sudai and Basac production areas in Bordeaux, France, Tokaj production areas in Hungary, and Rheingau production areas in Germany. The noble rot wines produced in these regions are world-renowned, and the production is limited and the price is high.

In fact, it is not really bad. It’s just that the grape particles are infected by a mold called Botrytis Cinerea. This infection process not only makes the already sweet grape fruit sweeter, but also produces glycerin that makes the taste more smooth and moist, and forms Extraordinarily moving and full aroma.

Botrytis mold is very arrogant. It cannot appear and spread in any vineyard. It needs a unique microclimate to produce-cold and humid in the morning, and dry and hot in the afternoon.

The humid weather in the morning is conducive to the growth and spread of this kind of mold, and the thousands of hot weather after noon can make the water in the grape berries evaporate from the infection, and dehydration improves the sweetness of the grapes. It’s easy to say, but the world has such a unique geographical environment, and there are only a few vineyard producing areas that create such harsh climatic conditions. There are rivers in Bordeaux and Hungary. In the morning, both sides of the river are often filled with mist. Then the sun and wind gradually dissipated the mist. At noon, the sun was shining and inhibited the growth of mold.

Even so, noble rot wine is not produced every year, because if the weather is abnormal, even the “god-given” producing areas will be helpless. Vineyard owners have to risk the rot of the grapes every year and wait for real concentrated grapes to make wine.

The editor of Yada Family Brewing Equipment reminds you that you need specific weather conditions to get it, don’t try it lightly!

There is also a kind of wine called ice grape wine, which is produced in ice and snow, and is a precious gift of ice and snow-ice wine.

Ice wine is made from frozen grapes. Unlike most wine grapes that are harvested when they are ripe in autumn, ice grapes will still hang for several months after they are ripe, and will not be harvested until the temperature reaches minus 10 degrees Celsius after winter and the grapes are completely frozen on the trees.

After the ice grapes are harvested, they need to be transported to the winery immediately, where they are crushed and pressed under low temperature conditions. After pressing, the ice in the grapes is retained in the press, which is equivalent to removing the moisture in the grapes. As a result, a very rich and sweet grape juice can be obtained, which is then subjected to alcohol fermentation. Ice wine has a 100% pure fresh fruit flavor, tastes as sweet as honey, tastes sweet and pure, and has a scarce yield and expensive.

Seeing here, you believe that it is not just fresh grapes that make wine. Of course, noble rot grapes, raisins and ice grapes all need specific weather conditions to get them. They are rare and expensive, so the wines made from them are very delicious and of course valuable.
