Most wine, the overwhelming majority of wine, made or imported into the USA up to the $20.00 price point, is meant to be consumed within a year or two of release. Sure some of these will get better in another year of two, and if you happen let that happen; fine. Most of the worlds wines (at least 90%) are meant to be consumed young. Of the hundreds of questions we get here at the wine board a large number come from people who have hung onto wine too long. We get very few from those who popped it too soon.
White wines are not generally cellared for long periods of time although there are exceptions such as the very best Graves and Sauternes for instance.
Red wines can be and are cellared for longer periods of time. Some of the very finest reds can be cellared for several decades. A lot depends on the type of grape and the vintage.
