12 Years Old Blended Scotch Whisky (1 L)

When John Dewar's sons codified the practice of returning a finished blend to oak casks for a further resting period, they created what the industry now calls marrying — and Dewar's 12 Year Old remains the clearest demonstration of that proprietary Double Aging process in action.

The heart of the blend is Aberfeldy single malt, drawn from the Pitilie Burn, a natural artesian spring on the rolling southern bank of the upper River Tay in Highland Perthshire — water of exceptional softness that, combined with extra-long larch washback fermentation and medium-height onion-shaped copper pot stills, produces the house's signature heather-honey new make.

Up to 30 single malt and grain whiskies — including worm-tub-condensed Craigellachie and the delicate Royal Brackla — are individually matured, then blended and re-casked in first-fill American oak ex-bourbon casks for a minimum six additional months before bottling at 40% ABV.

That post-blend rest is what separates this from most blends at the price: the component whiskies lose their seams. The special feature here is the first-fill bourbon finish applied specifically to the 12 Year Old — a step above the standard White Label marrying regime — amplifying vanilla and dried stone fruit without obscuring the Aberfeldy honey core.

As a non-vintage blend, consistency across batches is the benchmark; drinking window is open-ended.
