The next time you are in Jerusalem, Israel, check out the Mamilla Winery (wine bar) in the gorgeous Mamilla Hotel! The hotel is gorgeous, as is the wine bar and the roof top views! The wine options are solid, though no shocks, still, reasonable prices to taste wines that do not cost an entire bottle.
Sadly, this is the only kosher wine bar in Israel, that I know of. There are MANY wine bars that pour kosher wines, but this is the only one I know of that is 100% kosher, with a bit of supervision to boot.http://kosherwinemusings.com/2012/07/20 ... jerusalem/
