Jews aren't allowed to eat grains during Passover - which includes high fructose corn syrup.

So this time of year, Coke makes special batchs of Coke sweetened with good old sugar. Which tastes better than the corn syrup swill.

So if you're wanting the good stuff - or just want to try it and see if you can tell the difference, check out your grocery store. Passover cokes are marked with a little Hebrew type symbol on top of the cap. Those have pure sugar in them.
