What is Red Wine?

I worked in a winery when I was in college and on the tours we were asked many times what makes a red wine. Well after several glasses I couldn’t tell you but if you caught me early in the day I would tell you that Red wine in made by using a grape with a dark skin on it and then during the crushing period they would crush the skins with the grapes to get the color. Then the grapes would be put in oak casks and fermented until the right sugar and alcohol content. Enjoy your red wine.
