Mysterious single malt here from Signatory's Cask Strength Collection. This expression was distilled on the isle of Islay back in 1992 – though Signatory is giving no hints as to which distillery it came from. The whisky then aged in bourbon barrels, and was vatted in cask #6774 before being bottled in 2021 at 28 years of age. Only 237 bottles were produced.
