Serving as Oracle Corporation’s senior director of strategic accounts since 2006, Dr. Antoine Chaya has a PhD in information technology management, as well as numerous years of experience in the information technology field. When he isn’t working, Antoine Chaya likes to indulge in Napa Valley wines.

Napa Valley wineries offer a range of red and white wines. But what are the differences between the two, besides color? Though both types of wine are made from grapes, the processes used to make red and white wine differ slightly. White wine can be produced from either dark- or light-colored grapes, while red wine is made exclusively using dark-colored grapes. This is because the color of wine depends on the amount of tannin, a naturally occurring polyphenol, found in the skins, seeds, and stems of grapes. The production of white, or colorless, wine involves fermenting grape juice. On the other hand, red wine is made by fermenting grape juice, pieces of grapes, and grape stems. Fermenting all parts of the grapes effectively preserves the tannins, lending the wine its standard reddish quality.
