In my post on the white wines of Corton, I emphasized how important it is to look at the producer, not just the terroir in Burgundy. As an example, the Domaine Ponsot Corton Bressandes is about US $400 per bottle, the Domaine Poisot Corton Bressandes can be had for about US $100 (and there is only one letter difference in the name, haha).
Another terroir and vineyard focussed region is Piedmont. Yesterday, I came across a detailed analysis of the famous Rocche dell'Annunziata vineyard in La Morra. This vineyard is shared between 9 producers. Here are the prices of some of them for their bottles, from high to low.
Roberto Voerzio, US $280
Paolo Scavino $180
Renato Ratti $125
Mauro Veglio $80
Aurelio Settimo $53 (largest vineyard holdings)
Rocche Costamagna $45
The vineyard has special characteristics; attractive aromatics and elegance. But within this, there are significant differences between producers. And in the case of Piedmont, I suggest 75% of the price differences are explained by quality, 25% by positioning, marketing, and scarcity. In the case of Burgundy, it may be the reverse, as it would normally be by 'cult' producers, for example Screaming Eagle, Bryant Family, or Colgin in the US.
