Here's the situation: you're at dinner with three friends, and you all order wildly different entrees. One chooses a pasta with vegetables, some else goes for the fish, another orders steak, and last person gets the chicken. For dinners like this, how do you go about ordering wine to share?
I love movies that let you peek inside a subculture that you might not be able to access otherwise: Word Wars, which follows competitive Scrabble players, and Spellbound, which featured the kids vying to win the Scripps National Spelling Bee, are two that come to mind. I'd say that SOMM, which will be available on iTunes on June 21st, has more in common with these movies than wine documentaries like Mondovino or flicks like Sideways.
Choosing wine for someone else is tricky, but if your dad's really an oenophile, he'll probably appreciate the effort...and maybe even open the bottle to share with you.
