Inexpensive wines for a wedding brunch

[andee1]

For my upcoming wedding reception brunch, I wanted to serve a smooth inexpensive white wine and mimosas ( with an equally inexpensive champagne). The menu is as follows: Assorted omelettes, cold meats, asparagus and artichokes. Along with a french sponge cake for dessert, fruit salad and cream filled crepes will be served.

Any suggestions? My fiance and I are really red wine people, so we are a little out of our depth here :-)
