White wine differs from red wine in, first and most obviously, color. Under that skin, the pulpy part of a white grape is the same color as that of a red grape. The skin dictates the end color for red wine, which differs from the white's color determinates. This is mainly due to the pressing of the grapes. When white grapes are picked, they are immediately pressed and the juice is removed from the skins with little contact. Color in white wine does vary, often from the type of grape, occasionally from the use of wood.
