Sometime between 2000 and 2018 or so, there was a documentary-style movie that set out to answer this question: can a panel of judges determine which of two vintners created a bottle of wine based on their personalities? It took place in France. One of the vintners was very buttoned-up and strove to bring elegance to his wines. The other was the exact opposite. In fact, there's a scene of him lying in the driveway of his vineyard completely drunk and singing to the sky. They both used the same varietal, endured the same growing conditions...and in the end the panel did correctly match which wine went with which grower.
Does anyone know what film this was?
