After four decades drinking Coca-Cola sweetened with corn syrup, Americans are going to get the chance to buy the soda made from domestic cane sugar. But whether US farmers can meet that demand is unclear.

PepsiCo and Dr Pepper have sold versions of their flagship sodas sweetened with cane sugar since 2009. Coca-Cola has sold Mexican Coke — which uses cane sugar — in the U.S. since 2005, but it’s positioned a trendy alternative and sold in glass bottles. Coke with cane sugar will likely be more widely available.
