Imperial 17 Years Old 1995 Cask #50070 (A.D. Rattray)

Imperial closed in 1998 after a century of sporadic production and was taken down in 2013 to make way for Dalmunach, so its whisky now comes only from a closed distillery. This single cask was filled in 1995 and bottled by A.D. Rattray at 17 years old, for its Individual Cask Bottling range. Single cask number 50070 yielded 274 bottles, released for the Netherlands.

Imperial's spirit was light and fruity, the Speyside character built for blending, which is part of why single malt releases stayed uncommon. This bottling matured in ex-Bourbon American oak. Across 17 years, the toasted staves released vanillin, which reads as vanilla, and oak lactones, which carry coconut, while the cask char filtered heavier sulphur notes from the spirit.

Bottled at its natural cask strength of 53.1%, without dilution, the ex-Bourbon wood supplies furfural for toasted almond, eugenol for clove and warm spice, and maltol for a soft toffee sweetness. The long maturation draws tannins from the oak, drying the finish into clean wood.
