The Caol Ila 35 Year Old released by Diageo in 2014 was drawn from refill American oak casks filled in 1978 — barely six years after the distillery had been demolished and entirely rebuilt by the then-owners DCL. That early-1980s production sits at a particular crossroads in the distillery's history: the same long, narrow stills as today, but a different era of barley, malting and cask policy.
Bottled at 58.1% ABV without chill filtration or colouring, this is one of the oldest official Caol Ila releases ever offered. Thirty-five years in refill oak has done what only time can do to peated Islay spirit — the smoke is no longer a foreground note but a kind of background weather, integrated so thoroughly into the wax, fruit and salt of the dram that you almost stop noticing it.
The nose is all old wood and tropical dried fruit, the palate slips between coconut, lemon curd and a salty ember. The finish has the unmistakable resinous, almost mentholated quality that very old refill-cask Islay whiskies sometimes acquire — a quietness that seems to deepen the longer you sit with it.
It is, of course, ferociously expensive and ferociously rare, and not many drinkers will ever encounter it outside an auction catalogue or a generous tasting. But for those who do, the 35 Year Old stands as one of the most eloquent statements of what Caol Ila — and by extension Islay — can become when given enough patience, enough oxygen, and enough good refill wood. A magnificent thing.
