Is there blood in red wine?

No, absolutely not. Red wine, in all of it's many varieties, comes from red grapes, thus it's color. It can take on any variety of red coloring, texture, and flavor based on the fermenting and production process, type of grape(s) used, and region, but in the end a red wine contains only food-grade ingredients. At no point in time will a wine come into contact with an animal or blood. Doing so would result in the whole batch being contaminated, labeled unfit for consumption, and poured down the drain.
