From what I've read, a Catholic priest may be willing to perform the ceremony at the vineyard, but the marriage won't be recognized by the Catholic church unless the ceremony is perfomed in an actual church.
My FSIL was dealing with this for a while and ended up compromising with her priest. He is willing to perform a modified ceremony at the vineyard where they're getting married, but only after they've had a small private ceremony in the
church.
Either way, I've heard good things about these guys: http://www.whiterobedmonks.org/
Good luck!
