Longevity of Opus One and others

[lizzie101]

Can anyone tell me whether Opus One is a wine that can be aged well or if it is one that should be consumed early on? I really like Opus One and I have a bottle that I do not want to spoil. Someone told me it does not age well and that it should be consumed within a certain number of years of the vintage. Is this true and is there a general rule of thumb for knowing which wines to savor right away and which ones to hold onto for awhile before consuming? Thanks for your help!!!
