This is a non-age statement iteration of the Balvenie Classic. Like the Founder's Reserve bottlings from the same era, these were produced using now iconic cognac-style bottles, and are increasingly collectible.
First released in 1983, the Classic was one of the world's first whiskies to have undergone a secondary maturation, or "finishing." In this case it was sherry wood. The expression was rebranded as the "DoubleWood" and switched to a 12 year old age statement in 1993.
