The year written on a wine label is not the year the wine was made or produced. Rather, it signifies the year the grapes were harvested, to make the wine.
Many people are of the opinion that the year indicated on the wine label is the year it was made or bottled, but that's not correct.
So when next you see a wine labeled 2005 or 1975 or whichever year it is, know that it is the year the grapes were harvested, and it is known as Vintage. It is quite expensive too.
The grape used to produce a bottle of wine may be harvested in 1999, then the wine itself could be bottled in 2004, and released in 2008.
For a wine to pass as vintage, about 85-95% of the grapes used in making such wine must be harvested in a particular year.
Each vintage is a creation, singular and unique, that expresses both the character of the year, and the distinctiveness of the grapes.
Take Dom Perignon 2009 for example, the grapes were harvested in 2009, but the wine was released June 2017.
