The American Wine Society is an organization that promotes the appreciation of wine through education. They have been around for almost 50 years and have about 120 chapters and 5,000 members in the U.S.
One of the cool things about their website is their Vintage Chart. One of the really important things about wine and any other agricultural product is Terrior, or the interaction of the local environment with plant genetics. With grapes, some years are better than others in that there is more sun, less rain, etc., etc. that produces a better crop and a better (loosely applied) Vintage.
I hope readers will use This Vintage Chart when purchasing their next bottle of wine. It rates wines on an alpha numeric 1-10 (low to high) and a-d (high to low) scale. Typically, when purchasing wine, retailers will charge the same amount of money from a given vintner and pay little attention to that year's terrior. A 2011 wine with a very poor vintage rating typically costs the same as a 2013 at the top of it's game. One can also use this chart to purchase wines that would normally be off the radar based on geography.
I hope this helps readers make a more informed and economical wine purchase next time around!
