The majority of the Saburomaru malt was distilled in 2019 and is mainly made in Mizunara casks, bourbon casks, and sherry casks from Toga, Toyama Prefecture, bringing out a variety of flavors and peaty, sweet, and oaky notes derived from Mizunara. The blended grain malt liquor aged over 12 years is aged in roasting casks made in Inami and wine casks from Nagano Prefecture, combining and supporting each other in a multi-layered flavor.
