Red wine and white wine are two different types of wine, and their brewing processes are also very different. This article will introduce the differences in the brewing process between red wine and white wine from the perspectives of grape selection, fermentation process, and aging methods.

Firstly, the biggest difference between red wine and white wine lies in the grape variety used. Red wine mainly uses black skinned grapes, while white wine mainly uses white grapes. This is because the color of red wine comes from the grape skin, while white wine does not use grape skin, only grape juice. Therefore, in terms of grape selection, red wine needs to choose mature black skin grapes, while white wine chooses mature white skin grapes.

Secondly, the fermentation process of red wine and white wine is also different. The fermentation process of red wine requires the fermentation of grape juice and grape skin together, which can extract pigments and tannins from the grape skin, giving red wine a deep red color and rich taste. White wine, on the other hand, requires separating the grape juice from the grape skin and fermenting only the grape juice to maintain a clear color and light taste. In addition, the fermentation process of red wine is usually longer than that of white wine, because the presence of grape skins increases the fermentation time.

Finally, the aging methods of red wine and white wine are also different. Red wine usually needs to be aged in oak barrels, which can increase the complexity and taste of the wine, and give it changes in aroma and taste. White wine, on the other hand, is usually aged without the use of oak barrels to maintain its fresh and fruity characteristics.

In summary, there are significant differences between red wine and white wine in grape selection, fermentation process, and aging methods. These differences enable red wine and white wine to exhibit different color, taste, and flavor characteristics, meeting the different needs of different populations for wine.
