Differences:

One, the grape varieties are different

Red wine is made from red grapes fermented with their skins. Generally, the longer the maceration of the skins, the darker the color. Young red wines usually have a deep purplish or ruby red color. As they age, their color lightens to a garnet or masonry red. The color of red wines is also influenced by the varietal from which they are made. Some varietals are darker and produce darker wines, such as Cabernet Sauvignon and Syrah.

White wines can be made from both white and red grape varieties. In white winemaking, the grapes are pressed and the skins and seeds are removed before fermentation, which avoids extracting the pigments and tannins from the skins. The color of white wines can be classified as varying shades of greenish yellow, lemon yellow, golden yellow, amber and brown. Generally speaking, wines made from varieties such as Riesling and Pinot Gris have a very light lemon yellow color. Different winemaking processes also affect the color of the finished wine. In the case of Chardonnay, for example, Chardonnay wines that have been aged in oak barrels show a deeper golden yellow color; Chardonnay wines that have not been aged in oak barrels are lighter in color, with a light lemon yellow hue.

Second, the production process is different

Red wine is first fermented and then pressed, the grape juice along with the grape skins and seeds of the grapes together with the fermentation of the wine contains a large number of pigments and tannins.

White wines, on the other hand, are pressed and then fermented, with the must separated from the skins and seeds and then fermented separately.

The above is the difference between red wine and white wine, hope to take it
