Wine Enthusiast Magazine’s vintage chart is a year-by-year guide to the overall quality and drinkability of the wines from the world’s major winegrowing regions. The quality ratings are determined by our wine review panel of experts, based primarily on their tastings of current and previous vintage wines, but also on interviews with winemakers and knowledge of the weather and harvest conditions. Thus, ratings for 2012 are not included, as most of those wines are yet to be tasted. Vintage ratings are only loosely related to ratings of individual wines, and readers are reminded that some producers succeed even in difficult years. Drinkability colors are based on experience with past vintages and assume a high-quality wine and proper storage.
