For warm weather weddings, a simple champagne punch is best kept in an oversized punch bowl filled where people can serve themselves. There are many recipes, but sparkling wine and some kind of fruit juice will be your base. One popular version includes orange juice and peach schnapps along with sparkling wine and slices of fresh orange floating in the bowl. Make an ice ring using a Bundt cake pan to keep the punch nice and cool for your guests. To prevent your punch from getting too watery, freeze a ring of juice instead of water. You can also offer a variety of garnishes on a platter beside the bowl so each guest can add their own preference and personal touch.
