Wine fine filter is a device used to filter sediment in wine. It can filter out impurities and sediment such as fruit peels that exist in the liquid during the brewing process, improving product quality.
When making wine, the grape skins and flesh are pressed simultaneously, and the red pigment contained in red wine is released during the pressing of the grape skins. That's why all red wines are red in color. After juicing, the raw material for making wine - grape juice - can be obtained.
After fermentation, the sugar content in grapes will gradually be converted into alcohol and carbon dioxide. Therefore, during the fermentation process, the sugar content decreases while the alcohol content increases. To maintain the fruit flavor and freshness of wine, sulfur dioxide treatment must be added immediately after the fermentation process. Sulfur dioxide can prevent the oxidation of wine caused by oxygen in the air.
The storage process starts from the end of grape fermentation and enters the storage tank until the grapes are filled. There are significant differences in time due to different grape varieties, which can be further divided into the following steps: storage in stainless steel tanks, storage in oak barrels, freezing treatment, and filtration treatment.
Filtering wine is an important step throughout the entire winemaking process, which can be considered as one of the most significant and influential processes affecting product quality.
