Wine wasn't dicovered it was invented and the first wines were actually made in Israel not Italy.
You can ask the workers at your local liquor or package store for the best wine recommendations. There is also a wine enthusiasts magazine, which would tell you their favorite wines.
There are a variety of wines offered by HdV Wines. The Napa Valley based wine company specializes in creating some of the best Merlot available on the market today.

White wines are meant to be drunk in the first 3-4 years. Some of the best can be held for 10-20 but these are the exceptions to the rule. White wines do not have the tannins in them that red wines do so they don't last as long.
All wines are meant to be enjoyed with some food, but if you have to drink it by itself, pinot noir and cabernet are some of them.

Some wines last longer than others, so yes, there are types of wines best consumed sooner than later. Generally speaking white and fruit wines have a shorter lifespan, while reds (properly stored) last much longer.
It depends on what kind of wine it is.
