Terrible. I kept hoping it would improve with more air. It didn't. We dumped half the first bottle. Hoping it was just a bad one, I opened the second one. It was just as bad as the first. Two sips later it went down the drain. don't waste your money.
On the glowing recommendations of those who bought the 2006 Reserva I tried the 2007. I did not get beyond the first sip. It was vinegary and horrible, and it all was poured down the drain. I would not even use it for cooking. I have 2 more bottles to try when I can get my courage up, and will gladly report if I find a more positive outcome.
Very good. Even somewhat cab-ish.
