If you consider yourself a wine collector (or are looking for a gift idea for someone who is), you owe it to yourself to check out The World of Fine Wine magazine. At $169 for a U.S. subscription (it's British), this quarterly publication is not cheap. But it's very content-rich (216 pages in the latest issue #16) with in-depth articles on a broad range of topics and only a handful of advertisements. Relative to Decanter or the Wine Spectator, it feels like you're reading an academic journal of sorts but it also contains beautiful color photography and is printed on heavy stock paper so it lands on your coffee table with a loud thump.
You can download some sample articles by visiting their home page and scrolling down to the bottom. For example, here is a link to Burgundy 2004 En Primeur from Issue 11 and to Symington Family Ports from Issue 12.
I subscribed myself and am glad I did.
