Fre brand wines are available in most Associated Foods stores like Fresh Market, Dan's, Dick's, Peterson's, etc. Never, ever, ever use cooking wine. It not wine and is mostly salt.
Here are a couple of ideas. Go to a liquor store and buy a bottle of wine. If you only need a little bit ask the clerk if they have a "split". That's the best thing. Fre would be my second choice and Fred Wix always taught that if you're looking for a sweet taste you can substitute red grape juice for red wine or if you're looking for a tart taste (from a dry wine) you can substitute 1/2 balsamic vinegar and 1/2 water.
While unsq312 is correct that not all of the alcohol will cook out I give you this article that gives David O. McKay's perspective:
At a reception McKay attended, the hostess served rum cake. All the guests hesitated, watching to see what McKay would do. He smacked his lips and began to eat. When one guest expostulated, But President McKay, dont you know that is rum cake? McKay smiled and reminded the guest that the Word of Wisdom forbade drinking alcohol, not eating it. As the writer pointed out McKays point was simple and refreshing: Dont get hung up on the letter of the law to the point where you squeeze all of the spirit out of life.
