BRING OUT THE WHITE WINE
1. The Science
The theory is that white wine will dissolve the colour pigments that give red wine its signature hue. Red wine has pigments in it called anthocyanin that, depending on their pH level, appear more red, purple, or blue. These pigments essentially act like a naturally occurring dye, and the acids and tannins that accompany any decent Merlot or Malbec are bound to do damage as well.
2. Substitute for Water
Drenching the red wine stain in white wine will act much like water, filtering out the excess liquid. Make sure to hold the fabric taut, so that the white wine gets at as much rouge colour as possible.
