It’s a close call, but I like Dujac by a stem more than Ponsot. It’s the aromatic display of the former that does it for me. One of my favorite wines in the world in fact.
Both- but each for very different moods and occasions.
Good question from the OP- not trying to knock the discussion- but for me at least this is apples and oranges. In Burgundy with appelations and grape choices so well set in stone- it is producer where the variable comes in, and so when it comes to selecting what I want to drink on a given evening Dujac and Ponsot Clos de la Roche are as different in my mind as Lafite and Mouton.
But of course 1st choice is to compare the two at the same sitting! Always up for a little academic stimulation to accompany a good evening.
