Now is the season when grapes are on the market in large quantities, and many citizens choose to brew pure natural wine at home. However, recently, an explosion occurred when a woman was making wine in Dalian, Liaoning, causing many citizens to worry. The reporter interviewed wine experts about this, and the experts reminded that when making home-made wine, do not fill the grapes too full and do not tighten the lid too tightly.
Because the grapes will expand during the fermentation process, a large amount of gas will be produced. If it is overfilled, the wine juice will overflow, and if the cap is tightened too tightly, the bottle may explode. In addition, grape fermentation also requires trace amounts of oxygen. Qian Yong said that when loading grapes, it is best to leave a quarter or a third of the space.

In addition to safety factors, how to make wine to ensure its taste. Qian Yong, who has been dealing with the wine industry for many years, gave a series of suggestions from grape selection, grape washing, brewing to storage. Those who want to make their own wine Citizens, please take a look.
Selecting grapes: Qian Yong said that it is best to select purple-skinned and medium-sized grapes 15 days before ripening, remove the stems, and pick out rotten grape beads and shriveled beads.
Wash the grapes: Soak in light salt water for about 10 minutes, then rinse and dry until there are no water beads on the surface. He particularly emphasized that the white frost on the grape skins must not be washed off, because "there are a lot of wild yeasts on the white frost, which are needed for fermentation in making wine."
Fermented grapes: Wash your hands, crush the grapes, squeeze the grape flesh into the main fermenter, and then put the grape skins and grape seeds into the fermenter. He emphasized that never throw away the grape skins. , "First, there are wild yeasts on the grape skins, which can start natural fermentation. Second, the wine needs the color of the grape skins."
Ratio of grapes and sugar: Add sugar according to the ratio of 6 pounds of grapes to 1 pound of white sugar, and stir evenly. "Don't add too much sugar, otherwise it will affect the fermentation process."
Fermentation time: Due to the relatively high temperature in Chongqing in summer, the wine brewing process only takes about 20 days. "It should be noted that the longer the brewing time, the stronger the wine taste. If you don't like to drink strong wine, , you can shorten the brewing time appropriately." After the wine is brewed, just use gauze or a colander to filter the residue.
Storage wine: It is best to store brewed wine at 14°C-18°C, avoid strong light, and remember not to shake the wine frequently, otherwise the molecular structure of the wine will be disturbed by the vibration, thus affecting the taste. wait. Qian Yong also said that it is wrong to store the brewed wine vertically or in the refrigerator. It is best to lay it horizontally and keep the humidity between 50% and 80%.

●The best wine-making containers are earthen jars, ceramics, enamel, etc. Do not use glass, iron, aluminum, ordinary plastic pots, etc. as wine-making containers, otherwise it is easy to explode or even chemically react, producing toxic substance.
●Wine fermentation is temperature-controlled. If the control is not good, some microorganisms may ferment, which may cause harm to the human body.
