Russian World War II Cognac

This bottle of Cognac was given to me from a russian soldier/student that I befriended on a school trip to St. Petersburg in 2001. I have had it in my possession since then and recently moved some boxes around and found it again. I was told that it was given to his grandfather from the russian government after world war II but can not find any information on line to confirm/refute. I would assume that it is worth a pretty penny if it is real.
