Feedback about a drink recipe

[Fred588]

Most people here are aware that I have an interest in inventing or discovering interesting and different foods, especially carbonated beverages. On a whim I have put together a combination that seems to me to work extremely well. I have seen things on line that are somewhat similar but far from the same. Anyway, I would be very interested to know if anyone here has tried this. Or, if anyone decides to go ahead and try it I'd be very interested in your feedback.

The recipe is quite simple, simply mixing the following three things in roughly equal proportions:

1. Iced coffee of medium strength.
2. Grapefruit juice.
3. Carbonated water.

If you do try this, in addition to your overall opinion, I'd like to know if you like or dislike iced coffee and grapefruit juice separately, as this might well affect the overall opinion.

Also, if a drink as I describe has a name, I'd like to know that.
