What is red wine vinegar? It's basically the best red wine that has been left open so it goes sour.

What is the history of vinegar? Vinegar was first discovered by accident thousands of years ago when wine fermented too long. Although this incident probably occurred in many locations, the Sumerians were the first recorded civilization that found vinegar useful as a condiment and a preservative.

Used in Babylon in 5,000 BC, and also known to the Egyptians during the earliest times of the Pharaohs, vinegar is referred to in Ruth 2:14 and other chapters of the Holy Bible. The famous Greek Hippocrates is known to have prescribed the drinking of vinegar to his patients, and Julius Caesar's best armies drank it as a tonic to remain healthy and ward off disease.

The French later began producing vinaigre (vin means wine; aigre means sour) by purposefully leaving wine casks open for two to six months, then filtering it and allowing it to mature for months or years. In the mid-1800's, the famous scientist Louis Pasteur published a paper on the production, which is still widely referred to today.

Over the centuries, since the first barrel of wine vinegar was produced, it has become universally popular - valued for a wide range of uses, including food preservative and flavor enhancer.
