Coca-Cola and other soda brands don't just contain cancer-causing additives — new research from a French research institute has found that the leading cola brands, incuding Coca-Cola and Pepsi, may contain alcohol.

The amount is small, reports the Daily Mail, about 10 milligrams per liter, which calculates to about 0.01 percent ABV. The researchers from the National Institute of Consumption tested more than 19 brands and found traces of alcohol in more than half of them.

The scientific director for Coca-Cola France admitted that it was possible alcohol was used in making the secret recipe; and a spokesman from Pepsi said that while alcohol may be used in manufacturing, "Pepsi does not contain alcohol." The main reason for upset, says the Daily Mail, was the effect it would have on Muslim drinkers who are forbidden to drink alcohol. Coca-Cola responded and said, "The Paris Mosque has provided us with a certificate stating that our products can be consumed by the Muslim community in line with the religious opinions of the Committee of the Mosque of Paris." Still, we can't help but wonder what else is in our brightly colored cans.
