Very true. Some beers age well, and some are best fresh. A lot of belgian beers have lambics (controlled bacteria) introduced that produce funky flavors. These flavors change over time.

One thing to note. Just like wines, you really need to control temperature when aging beer. You also need to keep them out of UV light. Hops do not react well to IV light.
