Kanosuke Hioki Ghost Series: 23A• 23B • 23C The Ghost Series #23 (which is the collection featuring Hioki) is a triptych curated by Stefan van Eycken. This rare triptych explores the experimental grain spirits of the Kanosuke's Hioki distillery, featuring a New American Oak expression (#23A) and an Ex-Bourbon cask (#23B). The haunting finale, #23C, is a masterful vatting of the first two casks, further refined in Umeshu (plum liqueur) casks for a complex, fruit-forward finish that binds the series together.
