Inverleven was the name of a 'distillery within a distillery' at the grain producer Dumbarton, situated just north east of Glasgow. The malt whisky by this name was produced in pot stills, but with no official release, its use was primarily relegated to blends, resulting in scant few casks available since its closure in 1991. Matured for 32 years in a single refill bourbon barrels yielding just 91 bottles, it has produced a whisky of dark honey and seville orange peel flavours, with dried banana and toast almond flaouvrs. A unique note of crystallised violets lingers gently in the finish.
