White wines tend to be anything but a true "white" in the glass, instead, they put forth a spectrum of colour ranging from a light straw often with green tints to a deep golden yellow. The colour components of white wines are derived from the distinct grape varietals or blends used to make the wine. White wines are made from the grape juice and grape skin of green, gold or yellowish coloured grapes. In the case of champagne and sparkling wine, they can be made from white wine grapes or just the juice (not the skin) of select red grapes (often Pinot Noir).
