What are the ingredients for red wine?

1. Grapes: Red wine is made from red or black-skinned grape varieties, which give the wine its colour. Some common red wine grapes include Cabernet Sauvignon, Merlot, Pinot Noir, Syrah, and Zinfandel.

2. Yeast: Yeast is a type of fungus that converts the sugars in the grapes into alcohol.

3. Water: Water is the main component of wine, making up around 85% of its volume.

4. Sulphur dioxide: Sulphur dioxide is a preservative that is added to wine to prevent spoilage.

5. Other additives: Some winemakers may add other ingredients to their wine, such as sugar, acids, or tannins, to adjust the taste and balance of the wine.
