We're in search of a good recipe for a champagne or wine punch (or even sangria) to serve at our wedding this summer. I have a few recipes we traditionally make---but they all involve some amount of hard alcohol, and unfortunately our venue does not allow any hard alcohol.
So now I'm on the hunt for a good spirits-free recipe that might pair well with salumi/cheese, gourmet pizza, and salads. This will be an outside garden party, but in a very moderate climate (so doesn't need to be super-cooling or refreshing, since we'll be lucky if it breaks 70!) We'll also be serving local beers and wines, so this is primarily for those guests who would otherwise have cocktails.
Any suggestions or starting points would be terrific---thanks!
