1. Clean and remove stems.

Fresh grapes picked from grape plantations must first go through a strict cleaning process to remove dust attached to the grapes. Then, pick the grape berries from the comb-shaped stems. However, a few types of wine will deliberately retain a small number of branches. Because the branches and stems on the grapes contain a lot of tannins, reasonable use can add a lot of unique aroma to the wine.

2. Process the fruit.

This step mainly does two things. 1. Separate the grape skin and grape flesh. Grape skins and grape flesh are pressed at the same time. The grape juice is red and is the material for making red wine. It is mainly used to make white wine and other varieties that do not contain grape skins. 2. Preliminary pressing of grape juice.

3. Fermented raw juice.

After obtaining the original juice of the grapes, fermentation and winemaking can be carried out. The main process of fermentation is to gradually convert the sugar contained in the grapes into alcohol and carbon dioxide. Because, the longer the fermentation time, the less sugar in the grape juice and the higher the alcohol content. In this way, after a long period of fermentation and brewing, the grape juice can be turned into a wine with a unique taste.

4. Add sulfur dioxide.

Adding sulfur dioxide is an extremely important step in making wine. Because sulfur dioxide can prevent the oxidation of wine caused by oxygen in the air, it can preserve the fruity flavor and quality of wine.

5. Precipitation and filtration.

Generally, new wine must undergo its first sedimentation and barrel change about 3 weeks after fermentation. The second precipitation takes 4 to 6 weeks. Sometimes, even after changing barrels many times, a lot of impurity crystals will precipitate in the wine, which requires protein coagulation and clarification, which can improve the taste and balance of the wine. At the same time, this step also puts the greatest test on the winery’s technology. Whether a bottle of wine can be stored for a long time and the fusion of the wine's aroma are closely related to this step.

6. Encapsulation and transportation.

After 3-9 months of sealed storage, the wine is considered to be successfully brewed. At this time, the wine needs to be transferred from the original oak barrel to other containers for transportation or bottling for sale.

Now you know how wine is brewed, right? The above is just an introduction to the important wine-making steps. If each wine-making step is analyzed in detail, it will include 'raw material selection → sorting → destemming → detoxification → rinsing → crushing → main fermentation → pressing → post-fermentation → storage → clarification and filtration → bottling', etc. A dozen processes.
