Can't help you with wine making but I used to travel there a lot for work, so I have some other tips...
Best restaurant I've been to is The Quarter. Best place for beers, pool, live music, and socializing is Corned Beer. Best diner is Paul's...crazy inexpensive and love their breakfast. Martin's is a great lunch spot, also has some live music. Hikes up to the star are really nice. Don't miss your parking meter my a minute, the guy who monitors in his little cart is on top of his shit! If I think of anything else I'll let you know.
