What ingredients are in red and white wine?

Normally Red wine is made with red grapes, and White wine with white (greenish) grapes. Red wine get its color from the red skin being in the mix that get squeezed (with seeds and all), and left weeks fermenting. White wine is fermented without the skin and seeds (these are filtered out before starting the fermentation process). It is, though, possible to make white wine out of red grapes by removing the red skin prior to fermenting. This type of wine is called 'blanc de noirs' (white from black).
