Dewar's 25 Year Old Scotch Whiskey

Dewar's 25 Year Old is the prestige age-stated expression from one of Scotland's most recognised blended Scotch families — founded by John Dewar in 1846, built around Aberfeldy single malt, and here presenting a 25-year minimum aged blend that occupies the ultra-premium tier of the Dewar's range.

Dewar's pioneered the use of double-aging (returning the blend to casks for additional maturation after initial blending) — a technique that Dewar's calls 'Married' whisky, which produces a more integrated and cohesive final character than single-stage blending. At 25 years the combination of long maturation and double-aging creates a genuinely complex premium blended Scotch. Browse all Scotch whisky at Wooden Cork.

Frequently Asked Questions

What is Dewar's double-aging process?

After the initial blending of malt and grain whiskies, Dewar's returns the blend to oak casks for additional maturation — a process the brand calls 'marrying.' The extra time in wood allows the component whiskies to integrate and produce a more unified, cohesive character than they would achieve from a single maturation period.

What makes the 25 Year Old the prestige tier of the Dewar's range?

All component whiskies carry a minimum 25-year age statement — a significant commitment that places this expression above the 12, 15, and 18 Year expressions in the range. At 25 years the double-aging and long maturation produce a blend with genuine complexity and depth.
