In a nutshell:
A bold and Sherried style of Speyside Single Malt.
'Casg Annamh' is Gaelic for 'rare cask'. This recent addition to Aberlour's range is matured in a trio of casks - American oak, ex-Sherry and ex-Bourbon casks, but it's the Sherry influence which dominates. The result is confidently flavoursome whisky with a nuttiness and rich fruitiness alongside some cinnamon spice.
The finish is warm and biscuity sweet.
