From eRobertParker.com, the online Wine Advocate Vintage Guide. Fascinating guide of wines from 1970-2005. Wines are grouped by region and year, and each group is scored and given a letter code to identify the current maturity status of those wines (like Ready to Drink, Too Old and Early Maturing). The color coding represents ranges of the numeric scores.

The guide is interactive, so clicking on any of the rating circles brings you to a list of the specific wines grouped together for that region. For the specific wines, you can see their individual name, score, maturity level and price range.

A PDF version of the guide is available here for download.
