Inherited Wine Looking For Info

Hello Friends,

I’m making this post after recently inheriting a wine locker following a death in the family. My uncle passed away and left behind a collection that includes some exceptional bottles (Lafite, Latour, Haut-Brion, DRC, Screaming Eagle, etc.), along with a few wines that I would love to get informed second opinions on.

I have a solid background in Burgundy and completed my WSET Level 2 several years ago, so I’m comfortable with general structure, producers, and vintages — but I’m very aware of the limits of my knowledge, especially when it comes to long-term aging, mature drinking windows, and bottle evolution at this level.

All bottles were stored under excellent professional cellar conditions, so storage is not a concern. My main questions are

• Is this bottle meant to be aged this long?

• How does this vintage typically show with this producer?

• Where are we realistically in the drinking window today?

• And, from your own experience, would you open now, hold, or approach with caution?

• If possible what the value would be for the bottle?

Any insight from those with firsthand experience tasting mature examples would be greatly appreciated. Thanks in advance, and cheers.
