In the traditional sense, all wines are sweet wines, and the sugar content is above 50.0 g/L. Dry red wine is a word borrowed from champagne brewing, that is, wine brewed directly from pure grape juice without adding any additives such as water, spices and alcohol. After red grapes are pressed, the skins and cores of grapes are not filtered, and the grape juice is filtered after brewing into wine. In the process of brewing, the color of grape skin is dissolved into the wine, which is dry red wine. There are two kinds of dry red wine, one is simple filtration; The other is continuous pressing filter residue. Squeezed dry red wine contains more tannins and has a stronger taste. In other words, dry red is not sweet to drink.

Simply put, the difference between red wine and dry red wine is that any red wine can be called red wine, such as sweet red wine, while dry red is mainly limited to dry red.
