Zvi and Menachem, Hi....
Indeed I missed that post. Apologies.
With regard to Malbec one has to keep in mind that the vast majority of varietal wines made from this grape come from Argentina, most of the rest of the world using Malbec as a blending agent. Simply stated, Malbec has found its greatest strength in Argentina and I am quite certain that were I make up a list of the 100 or even 200 best Malbec releases in the last decade, 99% if not 100% of those would come from that country.
Because so little varietal Malbec is produced outside of South America, to the best of my knowledge there is to date only one winery producing a kosher edition and that is Israel's Teperberg. If anyone has information beyond that, I would much appreciate hearing about it. Also worth keeping in mind that wines that attain scores of 87 and 88 are indeed good to very good wines.
My tasting note for the Teperberg release follows.
Teperberg, Malbec, Terra, 2007: Nicely focused, with black cherry, currant and cocoa notes along with hints of sweet toast and vanilla. Medium-bodied, with soft tannins, most assuredly not an Argentinean Malbec but a very pleasant Mediterranean version. Drink now–2010. Score 88. K
