During Passover, some Coca-Cola bottling companies make small runs of Coke using cane sugar, rather than the ubiquitous High Fructose Corn Syrup (as corn is off-limits in some Jewish traditions during Passover).
So, if you like the real old-fashioned taste of sugar-based coke — look for the yellow caps!

Real bottle.
Real sugar.
Need to find some of this stuff.
