I enjoy the Darioush cabs very much, although they are on the oakier end of my personal taste spectrum, especially when young. I was a little put off by the oak in my glass when the 03 first came out, but tried another one in the last few months, and it was much more integrated. This is always a crowd pleaser amongst my friends and anyone that says that they like big reds, loves this wine. I think that it is improving with each passing year, and will try and do one a year for the next 3-4 years for my remaining bottles.
And, to Jasong, are you sure that it is the Darioush Signature Cabernet for $39? That sounds exactly like the price for the Caravan, which is Darioush's second label, as the big cab runs $60-70 anywhere that I have ever seen it, even at discount. If that is really the signature, then buy all you want and then please tell us where you found it so that we can clean out that supply!
