====Kola nuts for caffeine====
The kola nut acts as a flavoring and the original source of caffeine in Coca-Cola. It contains about 2.0 to 3.5% caffeine, and has a bitter flavor.

In 1911, the US government sued in ''[[United States v. Forty Barrels and Twenty Kegs of Coca-Cola]]'', hoping to force the Coca-Cola Company to remove caffeine from its formula. The court found that the syrup, when diluted as directed, would result in a beverage containing 1.21 [[Grain (unit)|grains]] (or 78.4&nbsp;mg) of caffeine per {{convert|8|USfloz|ml}} serving.<ref>{{caselaw source

 }}</ref> The case was decided in favor of the Coca-Cola Company at the district court, but subsequently in 1912, the US [[Pure Food and Drug Act]] was amended, adding caffeine to the list of "habit-forming" and "deleterious" substances which must be listed on a product's label. In 1913 the case was appealed to the [[Sixth Circuit]] in Cincinnati, where the ruling was affirmed, but then appealed again in 1916 to the Supreme Court, where the government effectively won as a new trial was ordered. The company then voluntarily reduced the amount of caffeine in its product, and offered to pay the government's legal costs to settle and avoid further litigation.

Coca-Cola contains 46&nbsp;mg of caffeine per 12 US fluid ounces (or 30.7&nbsp;mg per {{convert|8|USfloz|ml}} serving).<ref name= "Caff">{{cite book| author = Gene A.
