The oldest release in GlenDronach's 18th batch of single cask bottlings, this 30 year old expression was distilled back in 1990 and left to mature in a Pedro Ximénez sherry puncheon. After three decades, in 2020, that cask was cracked open and the single malt Scotch whisky was bottled up at cask strength with an outturn of 402 bottles.
