Cocktail in keg

[Mrcmb]

I brewed a year for a birthday party but I'm thinking of adding a second tap of some sort of cocktail in a keg. I'm thinking a vodka Arnold Palmer (john Daly) made with crystal light Should this be slightly carbonated or left flat. Looking for any towhee keg cocktails as well

Unless you’re going to get a nitrogen tank and regulator, using co2 is going to carbonate whatever is in the keg.
