The 43 year old Glendronach 1972 Single Cask #706 comes from the 2015 range of Glendronach single cask whiskies. It is an absolute gem. Highly sherried in a PX sherry butt, aged for 43 years and bottled at a decent 51.1% ABV. It’s a single malt whisky that everyone dreams of. Well, we do, to say the least.
