This single cask Suntory The Owner's Cask whisky was produced at the famous Yamazaki distillery in 1992. It was then aged in a hogshead cask for around 16 years before bottling in 2016. The cask, the 45th in the Owner's Cask program, was initially purchased by Koei Sangyo Co. Ltd but bottles like this one have since appeared on the market. With only 168 bottles produced, there aren't many around today, making it highly collectable.
