Coleus, there are some decent wineries in the North Fork. Try the Cabernet Franc from Pindar or Lenz. Its nowhere near as good as what is currently produced in California, Washington, or Oregon, but is still pretty good nonetheless.
There are a few wineries in Sussex County, and two down around Egg Harbor in the Pinelands, but I have never had any Jersey wine with the exception of some Dago red my grandparents neighbors in North Bergen made all those years ago. :-)
