Behold, some marvellously well-aged single malt from Islay's Bunnahabhain Distillery! This expression was distilled in November 1990 and allowed to mature for an impressive 30 years in a single refill hogshead cask. Following three decades of rest, this whisky was independently bottled by Douglas Laing for the Xtra Old Particular The Black Series range in April 2021. Just 291 bottles were produced.
