Calimocho, or jote, is a mixture of approximately equal amounts of red wine and Coca-Cola. Mixing a cheap, dry, tannic wine with Coke softens the harshness of the wine and balances out the sweetness of the soda. Of course, most cheap reds in the US are too sweet already, so it makes little to no sense to drink it in the US. Still, done properly, it’s actually quite good.
But, as I said, I think it’s a crime in France.
