I (naturally) prefer to drink the special bottles with her. But she drinks so little that it's hardly even noticeable!
When I am alone, I go for the extra thin and sour wines, because she likes more substance in her wines. But then again, I don't really buy anything that fits her ideal preference of Southern and robust. Which you might consider an oversight, but then again, she drinks so little, it's hardly even noticeable and not worth me choking through 99% of a bottle of Southern Rhone wine!
From time to time I think it could be nice if she shared more interest in wine. But we are who we are. And I wouldn't want to change her. I certainly wouldn't enjoy being married to a drunken sloppy mess on the other extreme!
