I really like
Klickitat Canyon stuff (full disclosure: a friend works for this winery).
they've been very intentional about maintaining and encouraging
native and endangered plants and birds on their
land, which is pretty rare for vineyards. I think they just use wild yeast, too, which turns out pretty great. I don't know wine real well, but I think it might be just a little bit of wild
Brettanomyces that's really pleasant in this wine.
Klickitat Canyon isn't very close to you, Jeanine, so the transportation required would likely ruin any illusions of "sustainability." it's a lot closer than Sudamerica or Europe, though.
other than that, I would also second the make-your-own suggestion. I make a fair amount of cider and mead. tasty results are pretty easy to get, though really exceptional results are certainly not.
also: in many parts of the world, it's time to start vin
de noix and nocino, both of which are made with green walnuts. vin de noix uses a wine base, and nocino a liquor base, but they're both lovely.
