Q: Is wine really carbonated?

A: Yes

Yes! There is a measurable amount of CO2 dissolved in red and white wines. White wines contain more CO2 than red wines. Obviously, wine contains much less dissolved CO2 than carbonated soda or beer but the small amount of CO2 dissolved in wine plays an equally important roll in wine flavor and shelf life. Maintaining the naturally occurring dissolved CO2 levels in wine can extend the flavor profile of kegged wine significantly.
