Just Ask: How Is Vinegar Made?

Q: I use white vinegar as a natural cleaning product, but until recently I never asked how it was made or where it came from. When I finally did ask, I learned that some white vinegar may be produced from fermenting ethanol from natural gas or petroleum derivatives. If this is true, how can we be sure our vinegar is “natural”?
