What about "cokes" & grape juice? (+1 on calling all carbonated soft drinks "cokes"

)
As a kid I thought one of the world's great treats was an ice cold grape "coke". The main brands here back then were Nu-Grape & Grapette.
These days, I sometimes make my own grape "coke" by mixing a little real grape juice with a good lemon-lime, like Diet Sprite or Mist. Even better than the Grapettes & Nu-Grapes of old!
And strangely enough- I like it even better with Fresca.

Fresca and a little pineapple juice is very good too.
