In Canada there’s a product called Pepsi Throwback that’s made with cane sugar. Regular Coke and Pepsi here are a mix of can sugar and corn syrup.
One product available on both sides of the border that you might like is Jones Soda- their entire line is sweetened with cane sugar.
You can get throwback Pepsi here in the States as well as throwback Mt. Dew and Dr. Pepper. I think there was a run of throwback 7-Up as well. As the price of corn continues to rise to meet our federally mandated ethanol demands, I predict we'll see a return to the use of cane sugar as a sweetener. It's already happening with many products advertising "no HFCS" on their labels.
