Hanyu 20 Years Old 1991

Hanyu 20 Years Old 1991 is a single cask single malt distilled at the closed Hanyu distillery in Saitama Prefecture in 1991 and bottled in 2011 at cask strength by Ichiro Akuto. The 20-year maturation was conducted entirely within the bourbon oak family: a first-fill hogshead followed by a second-fill bourbon barrel, an extended journey through American oak without any sherry or wine finishing.

This pure bourbon-oak trajectory over two decades would have built the layered vanilla, cereal sweetness and honeyed fruit that defines the cleaner side of Hanyu's character. Where many Hanyu releases gain complexity from Oloroso or mizunara finishing, this bottling presents the distillate's own qualities more directly, with American oak providing structure and sweetness rather than dramatic aromatic contrast. At 57.3% cask strength the spirit is concentrated and focused.
