A Robert Parker rating increases the price with 15%

Decanter reports that a study shows that wines that get a rating from Parker on average gains 3€ (equivalent to 15% for the wines studied) compared to a wine that is not rated by Parker. The study is based on ‘primeur’ wines in Bordeaux. For the consumer it can then be expected that the price difference will be even greater. Maybe one conclusion can be that the Parker craze may be defeating itself: rated wines automatically become more expensive so if you want to find something that is good value-for-money you should look elsewhere?
