It happens to all of us, doesn't it? We enjoy a bottle of Spanish wine of a certain vintage, but when we go to the store to purchase more, that vintage is sold out. Should we buy the same wine of the next vintage? Although wineries strive for consistency, wines from the same winery can change from year to year depending on weather and other factors. So, it helps to know which vintages were rated highly in a particular region.
Below is a short list of web sites containing vintage charts that you may wish to use as a starting point or guide when selecting a Spanish wine.
El Corte Ingles is probably the largest department store chain in Spain, and has everything from women's shoes to travel agents under one roof. They also have a very respectable wine selection. The chart on their wine club web site lists all major Denominations of Origin and their ratings from 1992 to 2008 vintages. The source for the information is the regulating council of each Denomination of Origin (DO). If you wish, click on años anteriores and the vintages from 1970-1990 will appear.
An interesting note regarding this chart is that it appears in the book, "2008 Wines from Spain Far from Ordinary Wine Guide," by Wines from Spain, a division of the Trade Commission of Spain.
This page is very simple, but contains a large, very informative chart with vintage ratings from 1971 to 2009 for all DOs in Spain.
It is quite unique because it allows you to select one or more Denominations of Origin, then select the vintage years you are interested in. So, instead of viewing a huge chart, you can create your own comparison chart of only those vintages and DOs you want.
