Most wines are meant to be consumed when you buy them

This is a question that comes up a lot.  What wines should I try to age on my own?  I'll post this link below that will help answer that question. (see the heading "which wines age well") 

Based on this article a year after fermentation most wines are as good as they will be.  So consume between 1-5 years and you're OK. 
What I have heard is that less than 10% of reds and 5% of whites are ever meant to be aged past 5 years.  And according to this article, aging more than 5 yrs may actually reduce the quality of the wine.  But there are a few that will improve with age and appreciate in value.  See the article.
