Anyways, after doing some browsing online, I came across Dublin Dr. Pepper.  I kept wondering why Mexican Coke tastes so different from American Coke, and I found out that it's because it's made with cane sugar instead of high fructose corn syrup (HFCS).  There's a pretty big debate about the health risks that HFCS poses, but I believe the US uses a lot of it because the government heavily subsidizes corn.  I'm in no position to say if it's good or bad, but I will say that HFCS changes the taste of soda.
