seems my google-fu is not good tonight ...
I received a bottle of cognac directly from France :
"Grande Fine Champagne 1er Cru Cognac, Réserve No 1" from the Claudine Dudognon-Buraud" producer.
I'm not expert in cognac (or any other types of "brandy"); but from what I can understand from the label, it should be a 'great" or at least one of the better cognac.
I don't want to open it right now, since I don't know how well and how long it can stay open without going bad; and I do not want to spoil openning a good bottle now.
googling mostly reveals that the Dudognon-Buraud producer released an insanly expensive "bottle" of cognac; but not much on description or tasting notes.
