Why Cask Finishes Matter
What makes a great whisky even greater? The cask. Whisky spends years maturing in oak barrels, absorbing the character of the wood and what once lived in it. Cask finishing is the art of taking an already-mature spirit and giving it a second life - maturing it further in a different type of barrel (like a Sherry, Rum, or Tequila cask).
This “secondary maturation” unlocks depth, complexity and rare flavour profiles. It’s a method favoured by innovators, artisans, and flavour explorers - like us at Douglas Laing, where we champion bold, flavour-first whiskies with regional character and uncompromising quality.

How to Taste Cask - Finished Whisky

• Let it breathe in the glass.
• Taste once neat, then with a few drops of water.
