i'm not really up to date on my israeli wine. you can try stratsplace for that.

but i would try bordeaux varietals only. not PN. israel is a warm country. besides that. GHW also makes single vineyard wines from the unoccupied galilee.
i agree with otto about the heightswine, both that the pun is not funNY and that the wine is excellent.
from what i understand syrah/shiraz is all the rage there, currently. as it should be.
another correction - wines from the judean hills W of jerusalem and from the negev desert, which has baking days and freezing nights, can also be excellent.
as for personal preferences, i was never wowed by anything from golan heights. try the boutiques. my favourite is margalit, because he has a very distinct style. domaine du castel is v. good too. pelter, flam (for brett lovers), amphorae, clos de gat, are up there with the very best in the country. sea horse is good but has bottle variation problems. i have greatly enjoyed the reserve wines of saslove, and orna chillag's wines in the past, no idea if they're still good or not.
whites: some nice sauv blancs (pelter, and i used to like dalton), and the castel "C"hardonnay, currently available at the LCBO, but i'd rather buy 2-3 good niagara chards for the price. maybe some other chards as well. the "non-iced" GW from GHW is also decent as well as their riesling.
there is a slew of new wineries there every year. some wines are apparently being imported to the states, and the LCBO sometimes carries some margalits and castels for prices i am not willing to pay.
a muddled post but the folks at stratsplace will tell you more, including on how to source the wine in the US.
