I believe RC was the first to come out with caffeine free cola. I prefer that. I generally buy Sam's caffeine free diet now-a-days.
Not a cola, however. Original coca-cola still the best tasting, IMO. Too much sugar to consume on a daily basis, however. It's also handy to remove pesky rust...
I like that also, and correct me if I am wrong, but my precursory research on the ingredients says it is a mixture of real sugar and corn syrup. If that is the case, I really wish they would go all pure cane. That being said, it is better than most.
I'm not sure, but I don't remember seeing corn syrup listed in the ingredients. I know it isn't nearly as sticky feeling as the regular.
I would love to try a can of C&C or Double Cola. I have only had RC twice, although First Choice in The Netherlands is meant to be similar... Cool new design
It's green instead of brown, but it's got the caffeine! I prefer Kroger's store brand generic Mt Dew. Slightly less acidic, but goes well with tequila - instant Margarita!
