Buy some good wines and offer him a glass next time he is over. Let him start to associate fine wine with you, not her. I recommend wines from the Carneros Valley in California. I have found that you get what you pay for with wine, and a bottle of $20.- $30. is much better than a $10-$12. bottle. I'm sure everyone from California will say, "Of course, Sara is an idiot to have to figure that out."
