Temp00223, Welcome to the WS forums board.
I used to collect Dominus. I stopped with the 1997 vintage because I refused to pay $110 for a wine that was selling for $40/$50 in 1994! They doubled the production AND the price during the next five years! I believe I paid $91 for the 1996. Is the 1997 worth $99? Not to me; I just bought the 1997 Ferrari Carano Tresor for $45
(1997 Dominus, summary of a review by RM Parker.)
94 points, "showing fabulously well" 14.1% alcohol, silky, fleshy, opulent, gorgeous nose of roasted herbs, asian spices, coffee, jammy plum and black cherry. medium to full body, drink now or it can age for another 10 to 15 years.
The $99 for the 1997 Dominus is a 10% discount over what it was selling for 2 years ago, but 100% more than Dominus sold for in 1994. The 1997 Tresor is probably almost as rich (I haven't tasted either one yet), but you can get two bottles of Tresor for what you pay for one of the Dominus, and Tresor even has a much better looking bottle! Good luck with your decision.
