OK, so it's not really "Hog wine" but we came across this little winery in Paso Robles a couple of years ago...they use a European boar symbol on their wines. And oh yeah, they're very good. Thought someone might want to try it...I have no financial interest at all. The owner is a cool guy, former Penn St football player and later an LSU student but he loves the boar theme.
