I am hesitant to give you a time frame. For one, no one has perfect storage -I have seen people with real wine cellars still store their wines incorrectly- so it is very likely that your wine won’t age as well as it would in a perfect year. Also, 99 was a rather poor year and not one that ages particularly well…. for a Lafite.
That said, it’s a kick-ass bottle of wine –one of the best. In a perfect world, that wine would come of age just about now and mature for another twenty years. Realistically, I would drink it within the next two-five years.
Also, be prepared for the worst. The longer you hold a bottle, the greater the chance of spoilage. Make sure to have a backup bottle in case your beloved wine turns to poop in the glass. What time do you want me over? You can also check out our wine reviews here.
