For some reason, I only started following this site a few weeks ago. Very well designed and informative. There, I just popped in there and learned the Tabor, Mescha, 2003 has 15% Shiraz. And I really like the way they organize the reviews.
Make sure to look up reviews by Meir Ido. I can vouch for his good taste as well as for his rather austere compliments. That is, any wine he actually recommends is quite good.
