wine collectors

[paolo_r]

Good Evening,
I would like to find out about a guide (weather on-line or physical) of wine longevity.
You see, I have recently started a wine collection and well, I am starting with not-so-expensive bottles. As I have found ( and please correct me if I am wrong) that the more expensive wines, especially high-end Bordeaux and Montrachet are the longer lasting.
With this in mind, I am wondering if there is an obvious logic (i.e. a book) to which wines can last longer in my collection and which are going to be sacrifized in my table.
Thank you !
