We are the wine-bearing dinner guests this weekend where the entre is pork loin. That is all I know.
I assumed, perhaps mistakenly, that a Pinot Noir would go well, but I rarely see it mentioned in most pork/wine pairing searches. I and the host's wife are red wine drinkers; my wife and the host/cook are white wine drinkers.
My wife is hopelessly stuck on Sauvignon Blanc, so I probably will just take that as the white and make my choices easier.
The question is what varietal of red (sot specific vinterns, please, since I will not have a lot of time to shop around). In my cellar and within reach:
Rosse di Montalcino
Brunello do Montacino
A variety of Toscana IGTs
Several '05 Bordeaux
Oregon Pinot Noir
CA Cabs and Meritage
Chateauneuf de Pape
