None of our bottles will be kept for a really long period of time unless warranted. We tend to let them sit for a couple years at most and then drink them since then it gives us an excuse to buy more ^

The Gran Assemblage we brought back was the only one we thought about keeping for a long time. A couple folks I know told me it should keep for at least another 3-5 years (it's a 2003 vintage) but if you disagree then I certainly would appreciate your opinion.
