Product Description: We toast the insides of ancient whisky casks and use them to slowly age plum liqueur at our Yamazaki Distillery. Once matured, the liqueur is finished by blending with several types of whisky aged in plum liqueur barrels to impart deep, rich tones and mellow fragrances. Savor the aromas that arise from the toasted casks and the lingering luxury of the substantial aftertaste.
