I actually shared a bottle of the 2003 Herzog Special Reserve Syrah with Richardhod when he visited last fall - one of many that night, so my notes are terse: "9/24/2010 rated 88 points: A very interesting style - restrained and acidic. Some fruit hiding behind earthiness and leather. Interesting, but probably near its peak."
We were both of the opinion that it was a very restrained, Rhône-like style, and probably could have used a bit more decanting than it was given (that is, little to none). In fact, my subjective memory is that it was somewhat similar to the '06 Wellington England Crest I'm sipping right now, albeit much less brawny in character and a little less weighty in mouthfeel.
The kashrut process (which, as I understand it, is little more than gentle pasteurization, though I'm sure it must be more complicated) doesn't harm the texture, flavor, or character of the wine at all, but, much like FedEx leaving your case of wine in their hot aluminum toaster van all day, it does eliminate any possibility of substantial aging. I suspect these 2004's need to be drank this year, at the latest.
