What makes red wine stain?

The main compounds responsible for red wine stains are anthocyanin pigments, which are natural colorants found in the skin of red grapes. Anthocyanins are water-soluble and are easily absorbed into fabrics, making them difficult to remove.

Here are some additional factors that can contribute to red wine stains:

Tannins: Tannins are another type of polyphenol found in red wine. They can interact with proteins in fabrics and cause them to become discolored.

Acidity: The acidity of red wine can also contribute to staining. Acids can break down the fibers in fabrics, making them more susceptible to staining.

Sugar content: The sugar content of red wine can also play a role in staining. Sugars can attract dirt and grime, which can then become embedded in the fabric.

Fabric type: The type of fabric can also affect how easily it stains. Fabrics that are made from natural fibers, such as cotton and wool, are more likely to stain than fabrics that are made from synthetic fibers, such as polyester and nylon.

To prevent red wine stains, it is important to blot up spills immediately and rinse the area with cold water. It is also important to avoid using hot water, as this can set the stain. If the stain persists, it may be necessary to use a stain remover.
