Well, that's a HUGE FREAKING DIFFERENCE. They made this switch about 20 years ago, and Coke hasn't tasted the same since. Why don't y'all buy a clue and sell a version of genuine Coke with real sugar instead of trying to convince us it tastes the same?
The same is true with Dr. Pepper. They use the corn syrup in 99.9% of all Dr. Pepper's nationwide, however you can still get the original DP with cane sugar from the bottling plant in Waco, TX.
You can taste the difference.
The soft drink bottlers switched because the price of sugar in the United States is over twice as high as in the rest of the world, thanks to federal price supports for Florida cane growers and Minnesota beet growers. That's why Life Savers are now made in Canada, incidentally - the company literally moved the plant a few dozen miles from Michigan, because across the border the main ingredient was vastly cheaper.
So our modern, nasty, excessive-calorie-laden corn syrup Coke is the result of government agriculture subsidies. Quite a shame.
But: if you want real sugar cola, check out Real Soda where they sell Real Soda in Real Bottles. Anything you want, in actual glass bottles - imported Mexican Coca-Cola, real sugar Dr Pepper, Cheerwine, Nehi, you name it. I've grown to love Moxie. (No, I don't work for Real Soda - I just love their products).
