How is the Chateau Margaux? I am jealous. That one is a dream if I can order a glass of it.
I've had 1989 Chateau Margaux two times because I bought three bottles back in the mid-90's (yes, I'm an old dude). One tasting was way, way back in 2006 and another recently. The first was the most amazing wine experience of my wine drinking life; the last, not so much.
The first time was New Year's Eve, my birthday, and we had two bottles we opened at the beginning of dinner at about 7PM. We all tasted it and... it literally tasted like a barnyard. Honestly, perilously close to tasting like poop. I was bummed and concerned it had gone bad. But I knew enough about great old wine to know you really do have to let it breathe. So we all ordered other wine and champagne and set it to the side to wait for dinner.
Two hours later, when our entrees finally arrived - it was a fancy hotel restaurant and there were lots of apps and other tasty victuals - we sampled it again and it was jaw=droppingly good. I couldn't believe it was the same wine. It had become soft and subtle and fruit I never would have imagined could be in that liquid was there. We could still taste a little bit of dusty earth on the finish, but it wasn't barnyardy like before. Totally incredible.
The second tasting was just one bottle within the last year or two and, unfortunately, was not good at all because the wine actually had gone bad. But that's understandable given that it was pushing 35 years old and hadn't been stored in perfect conditions.
Anyway, I will tell you, if you can have one of those wines, give it time when you open it. You may be lucky and have my first experience and not my last!
