In 2006, Coca-Cola released a seemingly unholy concoction named Coca-Cola Blak: a Coke/coffee drink. Originally debuting in France, the drink was brought over to the United States and Canada in the same year. In 2007, Coca-Cola announced that they would discontinue the drink in the US once the original concentrate ran out and by 2008, the drink was discontinued everywhere.
Though the Canadian and French version of this drink was sweetened simply by sugar; the American version was sweetened with high fructose corn syrup, aspartame (aka, NutraSweet) and acesulfame potassium. This combination caused the American version to be significantly sweeter tasting than the other versions (acesulfame potassium is approximately 180 times sweeter than table sugar. Aspartame is approximately 200 times sweeter than table sugar.)
Though I can't vouch for the non-US versions of the drink, I will go down on the record as saying it was horrible. Admittedly, I'm not a fan of coffee, but even people I know who love coffee thought that Coca-Cola Blak was a terrible abomination of a drink.
