Wine is brewed after fermentation. Theoretically, when red wine is added to milk, protein in milk will solidify and egg-shaped precipitate will appear. The emulsified state of milk will be destroyed, so it is not milk, but milk residue and water.

But I haven't tried. I only once put fermented glutinous rice (sweet wine) into soybean milk. As a result, the protein in the soybean milk solidified into a flocculent, and became a clear soup, and the taste changed completely.

The chemical reaction between red wine and sweet wine and milk should be similar.

You can drink red wine first and then milk. It doesn't matter what they look like in your stomach.

You can drink it together, but you should pay attention to the fact that the red wine you drink must be light in body and light in taste, otherwise the two will not taste good without melting point. I suggest you drink black Pi Nuo grapes, which can go well with milk!
