Why Is Wine Red, White, or Rosé?

Contrary to popular belief, rosé wine isn’t just a mix of red and white wines, and white wine doesn’t always come from white grapes. In fact, the color of wine is not determined by the grape variety. Whether grapes are red or white, the juice is actually clear.

The color comes from the process of maceration, where the grape skins are left in contact with the juice during fermentation. This is what gives the wine its color, flavor, and tannins. Before this step, the juice is colorless.

• Red Wine: Made from red grapes, with the skins left in contact with the juice during fermentation. This is why red wine gets its color from the anthocyanins (color pigments) in the skins.

• White Wine: Can be made from both white and red grapes, but the skins are removed before fermentation. This keeps the juice clear.

• Rosé Wine: Made from red grapes, but the skins are only left in contact with the juice for a short time, giving it a pink color.

The intensity of the color in red wines depends on several factors:

• Grape variety
• Yield of the vineyard
• Soil and climate
• Length of fermentation (longer fermentation makes a darker, more tannic wine)
• Aging process
• Sugar content
• Age of the wine

So, the color of wine is influenced by how long the grape skins stay in the juice and other factors during production.
