I think I found what you're looking for. It's actually a bottled cocktail put out by Jack Daniels, called Tennessee Gold 'a mixure of ginger and lemon with Jack Daniels' There are several of the 'cocktails' put out by Jack Daniels and most of them are pretty damn good. I haven't seem them in the store, but I'm sure they are all over the place.
