A unique blended expression from Wakatsuru Saburomaru that was finished in some of the finest bourbon casks imported from Chicago. The casks have imparted sweet and woody notes onto the smooth spirit, including lashings of vanilla, oak and gentle citrus fruits, all the while much richer notes build in the background. As the producer has not specified which whiskies make up this blend, it's safe to assume that it includes some imported whisky and is therefore a world blended expression.
