Finishing of winemaking technology

The composition of wine is very complicated. Different wines have their own quality indicators. In order to make the quality of the wine uniform, maintain its inherent characteristics, and improve the shortcomings of wine quality or improved wine, it is common to sample and evaluate the chemical composition of the wine before it matures without leaving the factory.
Alcoholicity: If the alcohol concentration of the original wine is lower than the index, it is best to use the blended blend with high alcoholicity of the same variety, or to mix with the same variety of distilled spirits or refined alcohol.
Sugar: If there is not enough sugar in the sweet wine, it is better to use the same kind of concentrated fruit juice. It can also be prepared with refined sugar.
Acidity: Acidity is insufficient to make up with citric acid, and 1 gram of citric acid is equivalent to 0.935 grams of tartaric acid. Too high is neutralized with neutral potassium tartrate.
Toning: Red wines are light in shades and can be blended with richly colored wines. They can also be blended with wine pigments, but the former is better.
Fragrance: must use natural flavors of the same type of fruit.
After the blending, there is a clear and uncoordinated taste, and it is easy to produce sediment again. It needs to be stored for a while.
Bottling and preservation Bottling is the final process of wine. Qualified products can be bottled and stored.
Before bottling, it is necessary to conduct another fine filtration and determine its bottling maturity. Take a bottle of clean and disinfected bottles, hold the wine, place it in a tampon, place it in the light for a week at room temperature, keep it clear and not turbid, then use it to bottling.
