Dewar's The Ancestor is a blended Scotch whisky that is produced by the Dewar's distillery. The Ancestor is a blend of multiple single malt and single grain whiskies that have been aged for at least 12 years. The resulting whisky is smooth and well-balanced, with a rich, complex flavor profile.

The Ancestor is bottled at a strength of 40% ABV and is said to have notes of honey, vanilla, and oak on the palate, with a long, smooth finish. It is recommended to be enjoyed neat or with a splash of water to bring out the flavors. The whisky has won numerous awards, including a Gold Medal at the International Wine & Spirit Competition in 2007 and a Double Gold Medal at the San Francisco World Spirits Competition in 2010.

In addition to the standard The Ancestor, the Dewar's distillery also produces a number of limited edition expressions of the whisky, including The Ancestor Limited Edition, which is finished in casks that have previously been used to age port wine, and The Ancestor Signature, which is a special blend created by Dewar's master blender. These limited edition expressions often have different flavor profiles and higher proofs than the standard The Ancestor.
