Red wine can only be made from black grapes. The colour comes from the skin, if the skins are removed the wine will be white. Green grapes produce white wine only. Rose wine is made by leaving the skins in for a short period or by the blending of red and white.
Sweet, medium and dry refers to taste in relation to sugar content left after fermentation. Dry being unsweetened.
