A local liquor emporium, is having a clearance sale, and I stopped by this morning to check out their stock. Decided I want to try a nice cognac for my evening dram. I was given a bottle of Ferrand Ambre many years ago and was very impressed at the time, but haven't followed cognac since then. In my price range(sale price around $50/750ml), they have AE Dor VSOP, Kelt VSOP and Maison Park Borderies. Which of those should I get, and why?
