Matured in Sherry oak casks.

A'bunadh means 'of the origin' in Gaelic. It is a respectful toast to Aberlour's founder James Fleming, and to this day is produced in the tradition of the 19th century malts. Matured exclusively in Oloroso sherry butts, Aberlour a'bunadh is bottled at cask strength and without the use of modern chill-filtering methods ensuring a dark, luxurious and rich whisky.

This expression is well-known for it's particular intense flavour profile, imparted by the maturation in Spanish Oloroso sherry butts and by being bottled at cask strength - this batch, it sits at a burly 61% ABV. Also, 63 is the atomic number of Europium.
